Machining program compensation for wiper SW/FW insert

Compensations for DNMG / TNMG -SW / -FW

Compensations④,⑤ Internal, External, Face turning, tapered surface

Compensate the NC program as described in ④,⑤ 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
