9 . If you want to specify approach and retract motion for the operation, select the Macros tab page to specify

the desired transition paths.

The general procedure for this is described in Define Macros of an Operation.


You can use the contextual menu commands to insert or remove points and to assign local feedrates.

By selecting a circle, its center is taken as the point to machine.

Points of an associated sketch can also be selected.

Points can be defined by indicating on a user-defined plane.

Points can be defined by means of X, Y, Z coordinates in the machining axis system.

Create a Spot Drilling Operation

This task shows how to insert a Spot Drilling operation in the program.


q the geometry of the holes to be machined





Open the HoleMakingOperations.CATPart document, then select the desired Machining workbench from the Start menu.

Make the Manufacturing Program current in the specification tree.

1 . Select the Spot Drilling icon .

A Spot Drilling entity along with a default tool is added to the program.

The Spot Drilling dialog box appears directly at the Geometry tab page . This tab page includes an icon

representing a simple hole. There are several hot spots in the icon.

2 . Select red hole depth representation, then select the points to be spot drilled.You can do this by selecting the circular edges of holes.

In this case, the circle centers are taken as the points to be spot drilled.Just double click to end your selections.

3 . If needed, click on the tool axis symbol to invert the tool axis direction.

4 . Select the Strategy tab page to specify the following

machining parameters:

q approach clearance

q depth mode: by diameterThe diameter value used is the one specified in thegeometry tab page.

q dwell

q

compensation number depending on those available on thetool.

The other parameters are optional in this case.

5 . A tool is proposed by default when you want to create a machining operation.

Drills, Multi-diameter Drills, Spot Drills, and Center Drills can be used.Conical Mills can also be used.

If the proposed tool is not suitable, just select the Tool tab page to specify the tool you want to use. This is

described in Edit the Tool of an Operation.


Note that in the tool path represented in the strategy page, tool motion is as follows:

q Motion at machining feedrate from 1 to 2

q Dwell for the specified duration

q Retract at retract feedrate from 2 to 3.

7 . If you want to specify approach and retract motion for the operation, select the Macros tab page to specify

the desired transition paths. The general procedure for this is described in Define Macros of an Axial Machining

Operation.

8 . Before accepting the operation, you should check its validity by replaying the tool path.

Ex a m p le o f o u t p u t

If your PP table is customized with the following statement for Spot Drilling operations:

CYCLE/SPDRL, %MFG_TOTAL_DEPTH, %MFG_FEED_MACH_VALUE, &MFG_FEED_UNIT,

%MFG_CLEAR_TIP, DWELL, %MFG_DWELL_REVOL

A typical NC data output is as follows:

CYCLE/SPDRL, 25.000000, 500.000000, MMPM, 5.000000, DWELL, 3

You can use the Edit Cycle icon to edit or choose output syntaxes. For more information please refer to Editing

Cycle Syntaxes in Axial Machining Operations.

The parameters available for PP word syntaxes for this type of operation are described in the NC_SPOT_DRILLING

section of the Manufacturing Infrastructure User's Guide.
