No. 14 Gleason Generator.
Cradle Angle / Cradle
ratio gear chart doesn't
Match his.
 
 
 
 

Gear specs are correct
but cradle angle and gear
selection (chart) is not
clearly understood.
 
No.14 method for cradle angle
is different from No. 24.
It is concluded that
largest value in table
is meant to be the limit
(52.8 deg for No. 14
and 62.4 deg for No. 24).
Added tables in F1 help
screens when excess cradle
angle is warned.
 
Added user note input in
Main Menu at Help option.
Preserved PA input when

CPC24 user reported
that the chordal
thickness for toe
end was too small.
 
While investigating
the Toe problem, it
was discovered that
Backlash recommendations
were out of date.
 

Heel chordal thickness
is correct, but toe
chordal thickness is not.
 
Also, in a 1972 Gleason
revision, backlash for
straight bevel gears is
adopted from spiral gears;
i.e. backlash differs
over two ranges of
AGMA Quality Numbers.

Update should be made to
prevent possible confusion
between toe and heel
measurements.
 
Backlash recommendations
are explained in [F1]

Existing security uses
a PC ID and a correxponding
Activation Key. These now
use alpha/numeric characters
which can be confusing
and thus prone to error.

It would be an improvement
to use all numbers in new
PC ID's and ActivationKeys.
This should avoid future
confusion between numbers
and letters such as:
O and 0, I and 1,
and V and U
for examples.
 
It is important to preserve
current behavior so that
users who update their
earlier versions will not

Printer problem was reported
by user who installed on a Win7
platform. User reported an error
screen "Error 15...Line 0 Spu24"
 
Could not repeat the Error 15
as reported, but made a number of
"cleanup" changes and tested.
 
Testing reveals finding ratio of roll
gearset takes a looong time, so the
same User Preference used in CPC-HYP
was added to allow user to skip
ratio of roll. This speeds up "trial
and error" testing. This is only
helpful when installed on 64-bit
Windows which uses DosBox emulator.

Update is not required unless
skipping Ratio of Roll gearset
is desired and CPC-24 is installed
on 64-bit OS (e.g. Win7).

2/09/09 Not all ratio gearsets would physically mount on machine. Decimal ratios were correctly matched by gear sets but gear sets that could not be mounted were useless.
This would require users to sometimes use other means (e.g. Gleason's table of change gears) to find suitable ratio gear sets.
Versions of CPC-24 prior to 02/09/09 should be seriously considered for this update. Program changes now assure that ratio gear sets will properly mount on the machine.
Also, the table of missing change gear sizes is re-activated to define gear sizes not included in a standard Gleason change gear inventory.
The user may wish to add new gear sizes to the inventory and edit the gear table to permit those sizes. Missing sizes are listed here (and in F1 help screens) for convenience:
85,87,88,92,93,94,95,and 96.

06/05/08 Functionality to create summaries for Clutches (Face Gears) is missing.

30 Deg cutter pressure angle is unavailable.

Accidently clicking into the window would [Esc] back to an earlier screen.

Certain calculations involve ArcSine(x) and ArcCosine(x) functions. Mathematically,
values of "x" cannot exceed 1.0. Any calculation of "x" that leads to a value
larger than 1.0 ordinarily stops the process and quits the program. Some user
input combinations, while appearing harmless, can produce "x" values larger than 1.0.

Versions of CPC-2A/102 prior to 07/16/08 should be updated. Added "CLUTCH (FACE GEAR)" option to FORMATE method. See new System Menu option (in FORMATE method only!) to create Clutch gear summaries.
Reference to pinion has been removed from all screens and prints when "CLUTCH (FACE GEAR)" option is selected.
Added comments to Help topics concerning Clutch gears.

Improved screen navigation. Menu item must be selected to navigate forward/backward.

Calculation of values out of range for ASIN or ACOS are preemptively trapped to gracefully stop the processing and loop back to prior inputs safely.
These errors now return an E0n: number along with a message that can be reported to tech support.

30 Deg PA was added to cutter list (Formate only).

Posted Version 1.1003 to website 07/16/08
07/10/07 (1) Pitch angle was not recalculated when addendum changed.
(2) Finding Profile Factor (Kp) from Swing Angle was hit or miss when matching to an existing summary. Kp should be added to output print and preview.
(3) Added Revised Method to Standard and Formate methods. This is expected to make matching an existing summary easier.
(4) Linkage Setting added to Generating Cam selection screen would make staying under 1.400 easier.
(5) Some settings between members were different in the case of miter sets.
Versions of CPC-2A/102 prior to 07/30/07 should be updated. A lot of what was changed here has to do with making matches to existing summaries. Since there are many choices to be made while creating a summary, matching existing summaries is not so simple. Since matching has been expressed often in user comments, it seems a good idea to make matching an easier effort. Just remember that recreating a particular summary is NOT necessary to a successful summary. However matching builds confidence in the software and is a valuable way to learn the software. I regret to say that, until now, matching summaries was considered relatively unimportant.
 
Besides, while making changes for the purpose of matching, a number of real issues were uncovered.
 
(1) Pitch angle is recalculated for user changes in addendum or Whole Depth.
Also, maximum dedendum angle before undercut is now displayed.
(2) Standard Method only: Kp is recalculated when Swing Angle(s) are changed. Kp is also printed on the summary.
(3) Rather than incorporating all revisions into the one Standard method presented, changes not appearing in the original Standard (Book) Method have been extracted to the new Revised Method.
Standard Method now strictly follows the original documentation, while the Revised Method incorporates changes made by the OEM to the original method. To my knowledge, the documentation was never updated and distributed for these changes. It's not certain whether the Revised method is superior to the Standard, but it makes hand calculation easier. While not proven, there could be other justification in using the Revised method - but for now let's say it's just different. I would appreciate anyone's comments or experience in this area.
(4) Linkage setting was one of the last calculations made, but directly influences the choice of a generating cam. So linkage has been added to the Generating Cam selection screen.
(5) There's no reason for values and settings to vary between two miter members. It's possible for comparison's sake to force differences, but differences don't occur by default now. This issue has been corrected. Additional comments and hints are added to the Help facility.
Cutter Selections in the Formate Method are now in a separate window.

12/21/06 New user had a number of questions and, while investigating, the help facility for the FORMATE method was found wanting.

Found error in formate calculation
which shows up as "error 17".

This error does not permit continuing
since the error traps an arcsin
greater than 1.

This prevents user from creating
hypoid formate gear summaries.
Versions of CPC-UNI prior to 10/10/14 should be updated.

User reported an estimated DP
that resulted in an undersized
OD and an offset that wasn't
achievable. Found that problem
originated from bad estimate
of OD and DP derived by user
based on sample measurements.
 
Gear specs can be sensitive to
user's selection of DP. This is
especially true of Hypoid sets
since the offset pinion location
is often close to gear OD.

 
Symptoms may appear as
impossible cutter choices or
spiral angles. Net effect is
a summary process that reports
warnings and errors.
 
This can often happen when user
is working from samples and is
approximating a DP from gear's
Outside Diameter.
 
 
A bug (not related to OD/DP issue)
was found with no. 16 summary.
It shows up as a negative Radial.

It was decided that the best course
of action was to add a feature
that prompts user for the OD
(Outside Diameter) measurement.
Thus, if user originally had to
approximate DP (Diametral Pitch),
then the user can enter and change
the OD value and let CPC-UNI
recalculate DP.
 
When user is satisfied with DP
and OD values, user will simply
[Enter] at the OD input to continue
the summary process.
 
Unless DP is entered from a print
the value of DP can be questionable.

It is recommended that
user should download
and install this update !
 
The OD Input feature
is worth an update.
 
Besides, if you create
summaries for no. 16
you could experience the
negative radial!
 

Added new feature that
allows user to optionally
enter Outside Diameter.
This gives user an
accurate way to determine
Diametral Pitch (DP), since
program will calculate DP
based on OD.
 
also added help screens
to explain the problem
and the feature.
 
OD Input has been added
for all machine setups
that can be made
in CPC-UNI.
 
Since OD recognizes a
change in value, CPC-UNI
automatically redirects
user to the new value of DP.
Thus user is able to
either accept calculated
DP or not.

Many thanks to user who
found Gear Tilt Angle error.
He requested a summary for
hypoid set and Formate gear
on the No. 16 machine.

He needed to cut 22.5 Deg
Pressure angle using 20 Deg
Unitool Cutters.
Unitool Method does
NOT calculate machine
settings for a No. 16
machine. CPC-UNI calculates
no. 116 settings, then
converts them to no. 16
settings. PLEASE READ
NOTE about no.16
machine and Formate
cutting under the
"Action" heading.
 
Gear tilt is required only
when cutting a PA other
than 20 deg.
 
Conversion worksheet
should have used the
absolute values of
initial tilt angles
of gear.
Versions of CPC-UNI prior to 12/18/13 should be updated.
 

Fixed conversion of 116 to 16

Added the following
note to on-screen
help topic:
NOTE:
Gleason states that
the "old" no.16
machine is not to be
used for Formate
since it provides
no clamping device
to lock cradle and
work spindle during
cutting. Also, no.16

18" Cutter diameter was
found to be too limiting
for large diameter/large
DP gears with 35Deg
Spiral Angle.
 
 

Added 22" Dia to list
of selectable cutter
diameters.
 
Also added prompt for Gear
OD. If user changes OD then
program calculates the
corresponding Diametral
Pitch.
This is very useful
when attempting to
determine DP where only
samples are available.
 
 
 

While the improvement
in cutter selection may
be welcome, it is
up to the user to
decide on appropriate

How to Update Your Software

CPC-HOB is a simple and painless way to set up all types of gear hobbers. You select a machine, enter gear specs, and CPC-HOB creates a complete set of change gears - for differential or non-differential machines. You easily control table feed. Easily sets up machines without differentials to cut helical gears.

If you are cutting
hard materials; e.g.
tool steel, then
update is strongly
recommended.

Some users reported
problems with printing.
In working with users
that reported problems,
no one reported an error
message. Problems seemed
to be resolved with a
reinstallation.
 
Finally, on 5/09/14
user reported "Spooler
not enabled" error
window that stopped
the print utility from
loading. This was the
necessary "smoking
gun".
 

Printing from
windows print
manager doesn't
work in Win7
installation.
 
found that prfile.ini
wasn't found by PrFile
utility when placed into
c:\windows folder.
Reason:
"Start..." was pointing
to c:\windows\Prfile.ini
but should point to
home folder (%CD%).
 
Default version of Prfile.ini
should be installed along
with all other files.

This error surely forces
user to print using
the following work-around.
 
Printing workaround
requires the target
.txt file to be found
in CPCHOB\SUMMARY
folder and opened in
an editor (like notepad).
Editor would be
used to print.
 

No problem with
CPC-HOB program,
so Version Number
is not changed.
 
Tested on Win7 with
DosBox variant
of CPC-HOB.
 
Fresh install,
update, custom

It would be an improvement
to use all numbers in new

This should avoid future
confusion between numbers

04/18/05 (1) A user suggested that CPC-HOB should have a list of excluded Index Change Gears for each hobbing machine.

(2) Discovered a problem when user modifies a lead change gear set. Upon modifying and exiting the Lead change window, the original unmodified set was displayed. Entering and exiting again would display the correct set as modified, but this was not acceptable.

All Versions

11/20/04
11/11/04 Two errors reported:
(1) Index gear set sometimes includes a gear smaller than minimum index preference. This occurs as a result of a smaller index constant combined with a prime workpiece gear.
(2) Differential gearset for Type B machine and large prime teeth could fail with fatal error.
All Versions
of CPC-HOB

Version 2.413
11/11/04
09/03/04 Added new option to force Feed Change Gear sets to either 4 or 2 change gears for differential machines (Differential machines with fixed feed sums are unchanged).
Also automated feed gear creation to create 4 gear set when table feed requires it.
Versions of CPC-HOB prior to 09/13/04 should be considered for this update. New option added to CPC-HOB to to set preference to 4-gear Feed Gear Sets on differential machines. Modified CPC-HOB module and posted to website

04/17/04 Change gear pitch looses its decimal portion during setup.
The hob machine list table permits change gear pitch to be expressed with a decimal place (ex. 8.5) but the "Verify Hobbing Machine Data" screen (2nd screen in setup process) drops the decimal place prior to creating a setup.
Versions of CPC-HOB prior to 04/17/04 should be considered for this update to improve the fit of change gears at the machine. Corrected CPC-HOB to use decimal portion of change gear pitch. Modified CPC-HOB module and posted to website
Version 2.412
04/17/04
11/08/03 Variation of hobber design discovered.
There are hobbers that use decimal index constants (such as 0.075) in the denominator of the traditional index over teeth (index/teeth) expression for index change gears. Attempting to use the reciprocal (13.333...) as the numerator index value doesn't work since the reciprocal is a repeating decimal which cannot be entered as an exact value.
Versions of CPC-HOB prior to 11/08/03 should be considered for this update, esp. if using a hobber as described. Changed CPC-HOB to interpret a machine index value smaller than 1.0 as belonging in the denominator
of the index/teeth expression.

05/01/01 Problem of rounding a decimal index constant occurred in "C" type machine for helical gear under some circumstances.The following example reproduces the error for a non-differential machine with index constant = 7.5 and feed constant = 0.01875, IdxCC=8, IdxP=12 MinFD=30:
For a12NDP 44T 27 Deg 15 min LH gear and table feed = .036 CPC-HOB produced an incorrect index set of 23 x 32 / 45 x 94. The index gear set should be 32 x 42 / 84 x 94.
Versions of CPC-HOB prior to 05/01/01 have this bug and should be immediately replaced with this update. Corrected error in code Modified CPC-HOB module and posted to website

03/02/01 Index ratio and index gear set for some setups was using the rounded value of machine index constant. No error occured for integer value of index constant, but occured for some (but not all) setups on machines with decimal values of index constant. The following example reproduces the error for a non-differential machine with index constant = 7.5 and feed constant = 0.01875:
For a 2 Module 76T 9 Deg LH gear and table feed = .028 CPC-HOB produced an incorrect index set of 28 x 32 / 86 x 99. The index gear set should be 28 x 30 / 86 x 99.

(combined with
Version 1.0025
07/17/15)
 
 
 
03/02/14
 
Hypoid specs can be
sensitive to user's
selection of DP
since Pinion location
is often close to
gear radius.
 
Symptoms may appear
as impossible cutter
choices or spiral angles.
Net effect is a summary
process that reports
warnings and errors.
 
This can often happen
when user is working
from samples and is
approximating a DP
from gear's Outside
Diameter.
 
A recent case was an
estimated DP that
resulted in an undersized
OD and an offset that
wasn't achievable.
 
A bug (not related to
OD/DP issue) was
found with no. 116
summary.
The case can occur
that program could
lock up and force
user to exit.

It was decided that the best course
of action was to add a feature
that prompts user for the OD
(Outside Diameter) measurement.
Thus, if user originally had to
approximate DP (Diametral Pitch),
then the user can enter and change
the OD value and let CPC-HYP
recalculate DP.
When user is satisfied with DP
and OD values, user will simply
[Enter] at the OD input to continue
the summary process.
 
Unless DP is entered from a print
the value of DP can be questionable.

It is recommended that
user should download
and install this update !
 
The OD Input feature
is worth an update.
 
Besides, if you create
summaries for no. 116
or 106 machine, you
could experience the
lockup bug!
 

Added new feature that
allows user to optionally
enter Outside Diameter.
This gives user an
accurate way to determine
Diametral Pitch (DP), since
program will calculate DP
based on OD.
 
also added help screens to
explain the problem and the
feature.
 
OD Input has been added
for all machine setups
that can be made
in CPC-HYP.
 
Since OD recognizes a
change in value, CPC-HYP
automatically redirects
user to the new value of DP.
Thus user is able to
either accept calculated
DP or not.

Fatal error occurs
for specific
conditions.
See Description
for details.
 
Discovery? between
09/02 and 09/06/13

This problem may have been around
for some time, but I only recently
discovered it during testing. To
reproduce the problem try this
scenario:
 
Run CPCHYP and select No.26 machine.
[Enter] to next screen, then select
setup from history (actually, same result
occurs if creating new summary, but easier
to pick from history).
Continue [Enter]ing to gear blade
selection screen.
Reverse the steps by [Esc]ing until the
Select Service screen
is displayed.
Now, hit [Esc] once more and
fatal error should occur.
 
The scenario above is consistent
but picking any machine OTHER than
no.26 doesn't cause error. Reported
error number is spuious, indicating
an internal failure.
 
BTW, no one reported this fatal error!
 
 
Let us call this the "N534D error".
I found an error with no. 116 calcs
that may cause a noticeable error
in your no. 106 or 116 summaries.
The affected field is n534d, which
was applied in radians, not degrees.
This angle is summed with other
angles to produce Cradle Angle.
 

This update is especially
recommended to all users!
 
Fatal error kills program's
return to main menu, forcing
a restart.
Saved summaries are NOT
affected by the fatal error.
 
- The "N534D error" -
All summaries with the
exception of No.106 and
116 summaries are not
affected.
106 and 116 summaries
may have significant
errors in Cradle Angle.
If you have experienced
a problem with your 106
or 116 summaries where
Cradle Angle was suspect,
please update CPC-HYP
first, and then rerun
106 & 116 summaries
from history to see
if Cradle Angle changes.
 
We always appreciate your feedback.
So send your comments and findings to .
 
Thank you for your cooperation!

Fix required a slight change
in screen navigation; [Esc]ing
Select Service screen returns
to main menu now, but in earlier
version it should have displayed
the History of Summaries. This
change could not be avoided,
but should not pose a real problem
to user.
 
 
 

Posted to website 09/21/13

09/02/13
Date of discovery is vague,
since much work over time
has been applied.
 
It all started when a client
wanted to select cutters from
his inventory of cutters.
Then I discovered
two errors in summary print.
 
I found some problems with
internal workings that caused
fatal errors when new fields
were added to tables.
 
And the usual missing [F1]
help screens - always seems
to be some I've missed.
 

This update is especially
recommended to all users
since features and corrections
are many, such as summary
did not allow user to maintain
and use a cutter inventory.
 
Cutter inventory is not very
useful if user has to return
to main menu to add a cutter
needed by a summary.
Normally, a user would like to
add cutters to inventory when
selecting blade point widths.
 
We always appreciate your feedback.
So send your comments and findings to .
 
Thank you for your cooperation!

Added cutter inventory table
and Preference option to
select either Inventory or
Standard blade tables.
 
When Inventory option is chosen
(in the Options/Preferences
screen),
user can enter cutter data
at blade point width selection.
This "on the fly"
ability to add cutters during
summary creation should be
a desirable feature.
 
When cutter is added during
blade selection, the status
of that cutters is
shown as "Requested" in
the cutter list. User may,
when convenient, review the
"Requested" cutters when
reviewing cutter inventory.
 
Full cutter inventory
maintenance has been added
(See at Main Menu/Options/
Cutter Inventory selection).
 
These changes and features
added many new topics to the
on-line help [F1].

Sporadic fatal errors that
require shutdown.
 
Index sizes are showing up
in some of the Ratio Roll
gear sets. This should not
occur since the same gear
inventory supplies both.
 
Deletion/Removal of summaries
was confusing. Should only
apply to machine as selected.
Cleanup Setup History from
menu [Options] tab could
apply to all summaries. [F1]
help screens don't explain.
 
Also, screen navigation
and screen artifacts need
to be cleaned up.

This update is especially
recommended to all users
to avoid the random fatal
error problem.

Fatal errors found to
be due to memory limits.
These errors appear
unexpectedly since mem
variable space can be
exceeded at any time
during program execution,
thus throwing a fatal
error at random program
lines.
This is a big program with
lots of variables, but is
easily fixed by raising
the mem var limit.
 
Marking summaries as
'deleted' is limited to
machine selection in
2nd screen [Cleanup]
option.
Actual Removal of
summaries applies only
when [Cleanup Setup]
is selected from
[Options] menu tab
in 1st screen.
 
Changes were cosmetic
but avoided some user
distractions.
 
Ratio roll gear code was
fixed to avoid sizes used
by index gear sets.

Download Update for CPC-DUP
How to Update Your Software

This setup module is for Gleason Spiral Generators with Helical Motion (H20). These machines use rotary face milling style cutters. Cutters control tooth bearing pattern. Often a range of cutters will be useable for a particular summary. CPC-DUP provides all dimensional input based on industry standards and suggests tooling. These default input values may be changed, but CPC-DUP informs you of questionable choices. Choices that won't work are prevented and explained.
