*B) Adjusting a Corner R Necessary to maintain a correct corner radius.
Adjust the work diameter to the same as the taper to prevent over-cut.

In correcting corner radius:
It is not necessary to adjust the machining programme, however, machining errors can occur within max.
The Easy-to-correct Method ±0.03mm due to correcting by an approximate number.
Corner Radius Correction Input the correction number of each corner radius.
The value of corrected corner radius Ex):In the case of machining a corner with a radius R 2.0 when using
= approximation an insert with a corner radius R 1.2.
*No need to adjust the programme in this case.

Others) The value of correction is same for both DNMX and TNMX. Discriminate them by the size of corner radius.
