Measuring drills - Special applications
Prerequisite
The tool probe has been calibrated with G18 active as is usual for turning tools.
Function
If drills are used on lathes with a length
correction (offset) as for milling machines
(SD 42950: TOOL_LENGTH_TYPE=0), then
a drill can also be measured (gauged) in this
application.
Length L1 is always calculated in the
applicate (tool offset axis) of the current
plane G17 to G19. This also characterizes
the position of the tool. The usual position
definition in _MVAR (5th digit) is no longer
relevant and is ignored.
G17: L1 in Z axis (corresponds to axial
position)
G18: L1 in Y axis (no turning machine
application)
G19: L1 in X axis (corresponds to radial
position)
Length L1 is determined if the following conditions are satisfied:
● the active tool is of type 2xy (drill)
● SD 42950: TOOL_LENGTH_TYPE=0
