Tool geometry variables (length, radius)
T Tool carrier reference point
R Tool radius
L Tool length
The tool geometry variables consist of several components (geometry, wear). The control
computes the components to a resulting size (e.g. total length 1, total radius). The relevant
overall dimension becomes operative when the offset memory is activated.
How these values are calculated in the axes is determined by the tool type and the current plane
(G17/G18/G19).
2.5.5 Tool types
2.5.5.1 Tool type number and tool groups
Each tool type is assigned a unique 3-digit number. The assignment of the tool to one of the
following technologies or tool groups is realized using the first digit (the hundreds position):
