This task shows you how to use the Machine Editor to assign
a machine to a Part Operation. |
|
1. |
Click Machine
in the Part Operation dialog box.
The Machine Editor
dialog box appears. |
|
|
|
|
2. |
Select the desired machine tool in one of the following ways.
- By clicking a
Default machine icon
:
Note: Instead of using a default
horizontal or vertical lathe machine,
you are recommended to use a multi-slide
lathe machine restricted to one spindle
and one turret.
- By clicking Assign
a Machine by File Selection
then selecting a Generic machine:
A generic machine is a CATProduct
representation that was created using
the NC Machine Tool Builder product.
Available
machine types are:
- 3-axis machine with no rotary
axis
- 3-axis machine with 1 rotary
axis on table
- 3-axis machine with 2 rotary
axes on table
- 3-axis machine with 1 rotary
axis on table and 1 rotary axis
on head
- 3-axis machine with 1 rotary
axis on head
- 3-axis machine with 2 rotary
axes on head
- 5-axis continuous machine (without
generation of ROTABL or ROTHEAD
instruction)
-
Multi-slide lathe machine
such as:
- conventional lathe
machine with single turret and
single spindle
- lathe machine having
multi turrets and single spindle
- lathe machine having
multiple turrets and multiple
spindles.
Each machine contains all the necessary
NC parameters and kinematic definition
data for the Part Operation.
A number of sample generic machines
are provided at this location:
..\OS\startup\Manufacturing\Samples\NCMachineToollib\DEVICES .
- By clicking Assign a Machine
by ResourceList Selection
to select a Generic machine directly from the PPR tree:
Only machines created using NC Machine
Tool Builder can be selected in the
ResourceList. Default machines cannot
be selected in this way.
|
|
|
|
|
The characteristics of the selected machine are displayed and
the following parameters can be edited to correspond to your
actual machine tool. |
|
|
Machine Name and Comment
If needed, enter a new name for the machine and assign comments
to it.
|
|
|
Numerical Control Tab
You can also specify the following.
- Controller Emulator and Post Processor:
Select the desired emulator and PP from the
alphanumerically ordered lists of available emulators
and PPs.
Note that a Controller Emulator/Post Processor vendor must
be set in the
Tools > Options > Machining > Output tab.
- Post Processor words table: Select the
desired table from the alphanumerically ordered list of
available PP word tables.
Note that sample PP word
tables are delivered with the product in the ..\startup\manufacturing\PPTables
folder.
- NC data type: Defines whether APT, Clfile
or NC code is the preferred output type.
- NC data format: Defines whether tool point
coordinates (x,y,z) or tool point coordinates and tool axis
components (x,y,z,i,j,k) is the preferred output format.
- Home point strategy: Defines whether a
GOTO or FROM instruction
is to be generated in the output APT source for the
Home Point.
- Rapid feedrate:
This is used to compute accurate machining time (in tool
path replay and NC documentation, for example) and
can be used to replace
the RAPID instruction in the output APT source.
- Axial/radial movement: Defines whether axial/radial
transitions are to be used between the end of one operation
and the start of the next operation.
Note that a Rapid GOTO statement is added for the
axial-radial movement if the option is selected.
- Min and Max interpolation radius
values are defined for generating circular interpolation
in NC data output. These parameters are used in tool path
computation and output file generation.
You should check and possibly modify these values before
creating machining operations. Otherwise, correct circular
interpolation may not appear in the NC data output.
Please note that if an interpolation value is modified after
machining operation creation and tool path generation, tool
paths should be recomputed (right-click Program and select
Compute Tool Path in Force computation mode) before generating
the output file. - 3D Nurbs
interpolation:
specifies the ability to generate NURBS data in an APT output file.
When this option is set, an Output tab will be available
in the Machining Operation dialog box (for all those
machining operations that support NURBS). Example:
If the Nurbs format checkbox in the
Output tab is selected, NURBS output data will be
generated for the machining operation. If it is not
selected, there will be no NURBS output data generated
for the operation.
See NURBS
Formats in APT Output for more
information about this type of output format.

Tooling Tab
Displays tooling parameters including the Tools catalog.
|
|
|
Spindle Tab
Displays spindle parameters.
|
|
|
Turret Tab
Displays turret parameters for vertical and multi-axis lathe
machines.
|
|
|
Rotary Table or Rotary Data Tab
For 3-axis machine with rotary table, rotary table parameters
are displayed.
For machines with more than one rotary axis on head or table,
parameters are displayed for each axis.
The rotary axis name can
be set on a generic machine in NC Machine Tool Builder. This
allows a better coverage of machines for automatic generation
of transition paths (for example, when the rotary axis of the
machine is not parallel to the X, Y or Z axis of the absolute
axis system).
|
|
|
Compensation
Cutter compensation options are
displayed for 3D contact compensation.
|
|
|
Use of the 3D contact compensation capability is restricted
as from V5R14 SP4.
Contact and Tip & Contact compensation
modes can no longer be globally applied to all operations
supporting this 3D Cutter compensation. |
|
|
The check box can only be selected when the No option
is selected (see example below), otherwise a warning message
is issued.
If the Contact or the Tip & Contact option
is selected and the check box is not selected (see example below),
a Compensation tab appears in the Strategy page of the machining
operation editor.
In this case, 3D contact compensation can be managed at machining
operation level.
Please note that some machining operations propose cutter compensation
modes other than 3D contact (2D radial profile, for example).
The table below specifies the
modes available for each machining operation that supports compensation.
|
|
|
NC Output
For generic machines created using the NC Machine Tool Builder
product, the Machine Editor centralizes all NC output options.
If such a machine is defined on the Part Operation, all options
for NC data generation can be read automatically from the machine
definition.
|
|
|
Generic machines (CATProducts) adhere to the Instance/Reference
mechanism described in CATProduct
and CATProcess Document Management. A generic machine is
added to the ResourceList in flexible mode. This means
that any modification to the machine in the CATProcess is valid
only for that instance of the machine in that CATProcess: the
modification is not propagated to the reference (that is, the
CATProduct file). |
|
3. |
Click OK to validate any modified machine parameters and assign
the machine to the Part Operation. The Part Operation dialog
box is displayed again. The Resource List is updated with
selected machine.
|
|
Example of a selected Default machine:
|
|
Example of a selected Generic machine:
In this case the machine appears directly in the
3D viewer. It is possible to use the Hide/Show
contextual command on the machine nodes in the tree
to hide all or part of the machine.

Machining Operations Supporting Cutter Compensation
The following table specifies
the Compensation output modes available for each operation.
Cutter compensation instructions are generated on the NC data
output depending on the selected mode as follows:
- 2D radial tip
Compensation is computed in a plane normal to the tool axis,
and activated with regard to a cutter side (left or right).
The radius that is compensated is the cutter radius.
Output is the tool tip point (XT).
- 2D radial profile
Compensation is computed in a plane normal to the tool axis,
and activated with regard to a cutter side (left or right).
The radius that is compensated is the cutter radius.
Output is the tool profile point (XP).
- 3D radial
Compensation is computed along a 3D vector (PQR), normal
to the drive surface, in contact with the flank of the tool.
The radius that is compensated is the cutter radius.
Output is the tool tip point (XT) and PQR vector. Tool axis
vector (IJK) is output in multi-axis.
- 3D contact
Compensation is computed along a 3D vector (XN), normal
to the part surface, in contact with the end of the tool.
The radius that is compensated is the corner radius.
Output is the contact point (XC) and XN vector.
The tool tip point (XT) may also be given if this choice
is set on the machine.
Tool axis vector (IJK) is output in multi-axis.
