Overview
Software Concept
This software has been developed to allow the operator to grind or resharpen,
Compression cutting tool. This is achieved, by setting a number of parameters in
an interface, and which are stored to a database. These parameters are utilized
when the Compression cycle is called from a line of NC entry within a main tool
operation.

The one line of Coding (NC Entry) added in the standard operations will allow the
compression tool to be ground in the overall grinding process.




                                                                                3
Assumptions
Run this software only on the following ANCA products: TG7, MG7, RG7, TGX,
RGX running QNX Software.

The machine tool should be in good working condition and must be accurately
commissioned. The probe qualification should be run prior to installing this
software.

The operator should have a good understanding of ANCA software and
equipment.


Safety Precaution

Before this software is installed, the operator should run a standard backup from
the machine. Using the following procedure

Format a number of blank floppy disks

Use the menu driven backup utility
      Press F11
      Disk Utilities
      Backup User files




                                                                                    4
Software Loading for QNX system
Installing this software should only be performed by a qualified A&F software
Engineer.

This can be completed using the following method.

      Press the E-Stop on the machine
      Place the installation floppy in the drive
      Press F11
      Disk Utilities
      Install new software from floppy
      Follow the installation prompts




                                                                            5
Using the software
Software Startup
To run the A&F engineering compression software, it must be run from the
specials part program menu. This can be achieved by using the following steps

             Home out the machine, or error reset the CIMulator
             F12
             Specials
             AF Compression

Once this is completed, the operator will be presented with the main page of the
Compression cutter software interface.

Main Page




                                                                                   6
This page allows the operator to select the compression cutter operations that
they wish to incorporate into the standard set of operations.

These operations include Fluting, Digitize the sections (If you want to re-sharpen
the tool), Flute polish the tool (If you want to re-sharpen the tool – or perform a
finishing operation on the tool), Tertiary grind the tool or OD Grind the tool.

This page also allows the operator to specify the tool type, Number of Flutes,
Tool Diameter and Tool Helix.

Once these operations are selected, the operator can then enter the appropriate
pages that allow each operations parameters to be set. This is achieved by
selecting the appropriate button from the bottom of the page.

The buttons across the bottom of the page are as follows:

 LoadSave -         This button allows the operator to load a set of already know
values into the main database, for use, or save the current entered data in the
data parameter pages to a central store that can be later recalled.

   Flute    -      This button allows the operator to enter the Fluting
parameters page, and specify the parameters for the fluting operations.

    Digit   -      This button allows the operator to enter the Digitizing
parameters page, and specify the parameters for the digitizing operations.

  Polish    -      This button allows the operator to enter the Flute Polish
parameters page, and specify the parameters for the Flute Polish operations.

 OD Grd     -      This button allows the operator to enter the OD Grinding
parameters page, and specify the parameters for the OD Grinding operations.

   Tert      -     This button allows the operator to enter the Tertiary
operation parameters page, and specify the parameters for the tertiary operation.

    Exit      -       This button allows the operator to exit the software, but in
doing so sets that data for the master database to the values currently in the
interface. Whether this is a loaded set of values or new set of values. The
values that are in the parameter pages at the time of exiting will be the next set of
values used by the Compression grinding operations.




                                                                                    7
This page also includes some standard parameters that tell the machine some
tool information. These parameters include:

Cut Type           -       Compressions cutter tools consist of two different
                   sections, both of which are these sections are opposing helix
                   directions. This means that if the tool is a right hand cut,
                   then the first section is a right hand helix, and the second is
                   a left hand helix. Where as if the tool type is a left hand cut,
                   then the first section is a left hand helix, and the second
                   section is a right hand cut.

Number of Flutes   -      This depicts the number of flutes that are present on
                   the tool. This is the number of flutes on each section. The
                   number of flutes can be either 2,3, or 4 flutes.

Tool Diameter      -       This is the overall tool diameter, and is the diameter
                   that is specified in the standard OD digitizing operation as
                   the blank diameter.

Tool Helix         -      This is the helix of both sections of the tool, whether
                   they are either right and or left hand.




                                                                                    8
Load and Save Menu
If the operator selects the LoadSave Button from the main page, then the
operator will have the option to save the current data to data file or load a set of
data from an already saved data file. The pressing of this button presents the
operator with the following page menu.




  Quit        -      This quits the load/Save file manager.

  Load       -       If the operator selects the “Load” menu, the following file
manager will then be presented to allow the operator to locate the existing file
and load the data file. This is the same file manager interface that operators are
used to using for loading and editing Part files.




                                                                                       9
   Save      -      If the operator selects the Save menu, the following file
manager will then be presented to allow the operator to save the current data in
the system to a data file.




Once again this is the same file manager interface that operators are used to
using for loading and editing Part files




                                                                                   10
Fluting Parameters
If the operator selects the Flute Button from the main page, the software
shows the “Fluting Parameters” page. This consists of two separate pages,
being the individual parameters, and the common parameters.

The first page presented shows the parameters that affect each flute individually.

Seen below, is the page shown, including detailed descriptions of each
parameter.




Section One (1) Parameters:

Parameters listed under the section one parameters include all the parameters
that describe the fluting geometry of the flutes on the front section of the tool.
Remember these are right hand helix right hand cut, if the tool is right hand cut
type. Conversely they left hand helix and left hand cut, if the tool is a left hand
cut tool.

X Start Position     -      This parameter describes the distance from the end of
                     tool that the first section fluting starts. This can be a positive
                     number, which is deeper into the tool, or a negative number,
                     which is further off the end of the tool.




                                                                                      11
Fl 1 X-Finish Pos   -      This parameter describes the distance from the end of
                    tool that the first section flute one (1) finishes on the tool.
                    Typically this is always a positive number.

Fl 2 X-Finish Pos   -      As the compression cutter software allows each
                    section and each flute to be independent, this parameter
                    describes the distance from the end of tool that the first
                    section flute two (2) finishes on the tool. Typically this is
                    always a positive number.

Fl 3 X-Finish Pos   -      This parameter describes the distance from the end of
                    tool that the first section flute three (3) finishes on the tool.
                    Typically this is always a positive number.

Fl 4 X-Finish Pos   -      This parameter describes the distance from the end of
                    tool that the first section flute four (4) finishes on the tool.
                    Typically this is always a positive number.

Sect 1 Common Hook      -      This parameter describes the hook for all the
                flutes on the first section of the tool.

Section Two (2) Parameters:

Parameters listed under the section two parameters include all the parameters
that describe the fluting geometry of the flutes on the second (back) section of
the tool.

Fl 1 X-Start Pos    -      This parameter describes the distance from the end of
                    tool that the second section flute one (1) starts on the tool.
                    Typically this is always a positive number.

Fl 2 X-Start Pos    -      As the compression cutter software allows each
                    section and each flute to be independent, this parameter
                    describes the distance from the end of tool that the second
                    section flute two (2) starts on the tool. Typically this is
                    always a positive number.

Fl 3 X-Start Pos    -      This parameter describes the distance from the end of
                    tool that the second section flute three (3) starts on the tool.
                    Typically this is always a positive number.



Fl 4 X-Start Pos    -      This parameter describes the distance from the end of
                    tool that the second section flute four (4) starts on the tool.



                                                                                    12
                       Typically this is always a positive number.

X Finish Position      -      This describes the distance from the end of tool that
                       the second section fluting ends. Typically this is always a
                       positive number.

Sect 2 Common Hook      -      This parameter describes the hook for all the
                flutes on the second section of the tool.

Sect 2 A-Axis Offset          -       This parameter describes the amount of A axis
                       rotation that the second section begins relative to the starting
                       A axis positions of the first section. Typically this value is
                       around the 180.0 degrees mark.




                                                                                      13

Digitizing Parameters
If the operator selects the Digit Button from the main page, the software
shows the “Digitizing Parameters” page.

Seen below, is the page shown, including detailed descriptions of each
parameter.




Sect 1 Index Dig    -       This parameter allows the operator the ability of
                    selecting if the Index positions of section one are going to be
                    digitized, and if this will be one or all flutes. (Values are
                    none, one or all).

Sect 1 Index Dig    -       This parameter allows the operator the ability of

Wheel Pack            -      This parameter describes the wheel pack number that
                      is used when performing the Tertiary Grinding of the tool.
                      This is only available on X Class machines.

Wheel Number          -     This parameter describes the wheel number that is
                      used when Tertiary grinding the tool.

Wheel RPM             -      This parameter describes the wheel speed (RPM) that
                      is used when Tertiary Grinding the tool.

X Gap                 -     This parameter describes the distance from the tool in
                      terms of X-Axis position from the end of the tool, that the
                      machine rapid moves to before slowing to the polishing rate.

Y Gap                 -     This parameter describes the distance from the tool in
                      terms of Y-Axis position from the OD of the tool, that the
                      machine rapid moves to before slowing to the polishing rate.

X Stop                -      This parameter allows the operator to specify the
                      distance away from tool relative to the wheel, that the
                      machine finishes the operation at in terms of X-Axis.

Y Stop                -      This parameter allows the operator to specify the
                      distance away from tool relative to the wheel, that the
                      machine finishes the operation at in terms of Y-Axis.

NC Entry Information
Once the operator has specified the part parameters in terms of operations and
particular parameters, they should then return to the main menu, select the
load/save option and save the parameters to a file so that in case of a needed
reboot, the values can easily be reloaded.

These parameters are then stored to a master database that is then reference
when used in the standard operations.

In order to use these operations in the standard software now, the operator
simply need to add the following line into the last box of the NC entry window for
any operation.

      callp “/tg7/pp/afcomp_map”

This will then call the appropriate operations for the compression software
grinding. These operations will then automatically reference the last loaded
values for the compression software interface.
