Explanations regarding the example above
Starting at block N390, various methods are used to approach position X0 Y0 Z0. The
machine positions reached are specified in the blocks in comments. After the program a
description is given of how the positions were reached.
N390: The adapter transformation 5 (block N90) transforms length L1 into length L2. Only the
actual adapter dimension is not subject to this transformation. The Y value (L2 with G17) results
from the sum of the tool length (10), tool wear (1), sum offset (0.1), and insert offset (0.01).
The adapter dimension (0.001) is in Z (L1).
N400: In block N350, bits 0 and 2 are enabled in setting data:
SD42935 $SC_WEAR_TRANSFORM (transformations for tool components)
This means that the tool wear and the insert offset are not subject to the adapter transformation
because of TOWMCS in block N400. The sum of these two compensations is 1.01. The Z position
