Editing V4 NCMill Operations

  When a tool path is created with the Associate output NC File to a program command, it is displayed in the PPR tree:

Tool path editor is available trough the contextual menu of the tool path in the specification tree

or in the Tool Path Management toolbar
.
However tool path editor is not supported by V4 NC Lathe Operation.

V4 NCMill Cycle Behavior

Tool path editor is available on NCMILL cycle operations.

Tool path of NCMILL cycle operations is created from APT file:

  • a drilling area is described by a PP word (CYCLE output syntax) and is represented by the GOTO statements of the CYCLE syntax. Links between CYCLE syntax and parameters are lost.
  • Macros motions (approach and retract) are described by tool path points.

The difference with V5 axial cycles is that the drilling area has no real representation and is described by the points located between CYCLE/DRILL and CYCLE/OFF in the APT file.

To modify:

Example:

Modifying Holes Depth

  1. Click PP Word Modification in Tool Path Editor dialog box.

  2. Edit the CYCLE syntax, and replace the 20.000 value of “CYCLE/DRILL, 20.000, 2.500, 1000.000” by the new depth value.
    Resulting APT is:

Modifying Feedrates

For Approach and Retract Feedrates

  1. Click Modify feedrate in the tool path area editor.

  2. Change the feedrates.

For plunge feedrate

  1. Click PP Word Modification in Tool Path Editor dialog box.

  2. Edit the CYCLE syntax, and replace the 1000. value of “CYCLE/DRILL, 20.000, 2.500, 1000.000” by the new feedrate value
    Resulting APT is:

Adding a Point in the CYCLE Output Syntax

  1. Click Point Modification in Tool Path Editor dialog box.

  2. Insert a point at

    between the 2 drilling points.
    Resulting APT is:
