Machining program compensation for wiper SW/FW insert
Compensations for DNMG / TNMG -SW / -FW
Compensations④,⑤,⑥ Internal, External, Face turning, tapered surface, corner radius
Compensate the NC program as described in ④~⑥ below.
Compensations④ 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.

Compensations⑤ Program compensations for tapered surface
(proceed after ④)
To machine tapered surfaces with DNMG or TNMG-SW/-FW insert, compensate both the x-axis and z-axis positions. Since these inserts are commonly used for profiling, to machine a tapered surface with a gradual reduction in diameter, the z-axis position has to be compensated in the negative direction.
Compensations for x- and z-axes when using DNMG or TNMG-SW/-FW
Match the insert nose radius and the angle of the surface taper to find the value in below to compensate the x-axis and/or z-axis positions.
* Match the taper angle and insert nose radius to find the value in Table 2 and compensate the NC program by either adding or deducting the value.
Example:
Tapering a surface of +45° (increase in diameter) with a R0.8 mm insert.
Current NC program: X100
Compensation value: -0.02
Parameter after compensation: X99.98
