Tool center point control
for 5-axis machining
Ed. Date Design Description

- Cutter compensation for 5-axis machining
When tool center point control is exercised together with cutter
compensation for 5-axis machining on a machine of mixed type or table
rotation type, specify a value in the workpiece coordinate system by setting
the parameter WKP (No. 19696) to 1.
In that case, when specifying cutter compensation for 5-axis machining
before tool center point control, specify the cancellation of cutter
compensation for 5-axis machining after canceling tool center point control
(example 1). When specifying tool center point control before cutter
compensation for 5-axis machining, specify the cancellation of tool center
point control after canceling three-dimensional cutter compensation
(example 2).
Example 1

G43.4 H1
:
G49
:
G40
Example 2

When specifying cutter compensation for 5-axis machining first, the block
for canceling tool center point control controls buffering. Note that, in a
block preceding the G49 block, the compensation vector for cutter
compensation for 5-axis machining is directed toward the vertical direction
of movement.
