Path Functions for Positioning Blocks
Assumption
Regardless of whether the tool or the workpiece is actually moving, you
always program as if the tool is moving and the workpiece is stationary.
Entering the target positions
Target positions can be entered in Cartesian or polar coordinates—either
as absolute or incremental values, or with both absolute and incremental
values in the same block.
Entries in the positioning block
A complete positioning block contains the following data:
„ Path function
„ Coordinates of the contour element end points (target position)
„ Radius compensation RR/RL/R0
„ Feed rate F
„

Before you execute a part program, always pre-position the
tool to prevent the possibility of damaging the tool or
workpiece!
