Machining program compensation for wiper SW/FW insert

Compensations for CNMG/WNMG -SW / -FW

Compensations①,②,③ Internal, External, Face turning, tapered surface, corner radius

Compensate the NC program as described in ①~③ below.

Compensations① Tool offsets (Compensations for X- and Z-axis)

Match the insert approach angle and the insert style to find the value and compensate the machining program for the insert radius.

*This compensation procedure will not be necessary if the insert is compensated with the built-in tool presetter after insert replacement.

CNMG/WNMG-SW/-FW (Type L)
Nose
Radius 		X-axis
direction		 Z-axis
direction
R0.4 0.03 0.03
R0.8 0.05 0.05
R1.2 0.05 0.05

Compensations② Program compensations for tapered surface
(proceed after ①)

To machine tapered surfaces, compensate the nose radius position in the x-axis position to obtain the correct workpiece dimension.

Compensations for x-axis when using CNMG or WNMG-SW/-FW (Tool approach angle: L) insert

Match the insert nose radius and the angle of the surface taper to find the value in Table 1 below to compensate the x-axis position.

Compensations③ Program compensation for corner radii (proceed after ①)

To achieve the correct corner radius dimension on the workpiece, compensate the tool position, using the values listed below for respective insert styles.
