7.2.1 Work Zero Point Offset Measurement

Work Zero Point Offset Measurement, if Tool Length Equals to Coordinate Shift

If tool lengths are measured so that they also contain the offsets of the work zero point (see tool length measurement) work off-

sets do not have to be measured. An exception to this if the offset needs to be compensated, as well

as if another work coordinate

system is to be used. This is

needed, for the tool length is calculated in relation to a given work coordinate system.

The process corresponds to the above discussed one. The control

calculates the offset amount with the help of the above-mentioned

equation:

Mx = x – xc – x0 Mz = z – zc – z0

However this time the offset of the new coordinate system (G55) is shifted in relation to the previous one (G54), as seen on the diagram beside.
