3.4.1

Measuring a workpiece on a milling/turning machine

General
This chapter refers to measuring a workpiece on milling/turning machines. Milling is set up as
the 1st technology and turning as the 2nd technology.
Preconditions:
1. Milling: MD52200 $MCS_TECHNOLOGY = 2
2. Turning: MD52201 $MCS_TECHNOLOGY_EXTENSION = 1
Further, the following setting data must be set:
● SD 42950 $SC_TOOL_LENGTH_TYPE = 3
● SD 42940 $SC_TOOL_LENGTH_CONST = 17
● SD 42942 $SC_TOOL_LENGTH_CONST_T = 19
Measuring workpieces using turning technology on a milling machine is realized using milling
technology. For example, if the outer diameter of a contour is to be measured, then this can
be realized using CYCLE977 "Measure spigot" at the G17 plane. If the measured values are
to be corrected in a turning tool, then the programmer must specify the tool lengths L3x or L1z
to be corrected, and possibly the sign of the correction. The selection of the correction depends
on the turning tool orientation (align turning tool function beta and gamma) for turning.
Please take into account SD55760 $SNS_MEA_FUNCTION_MASK_PIECE bit12 and bit13.
It only makes sense to correct the measured values of the turned tool in a work offset for the
Z axis. The machine manufacturer makes the correct setting of the turning center in XY when
commissioning the machine.
Note the machine manufacturer's instructions
If the tool probe is to be reorientated for making the measurement, then this is realized using
the swivel plane function (CYCLE800).
Additional settings/notes relating to milling/turning technology should be taken from IM9 –
Chapter "Turning on milling machines".
The descriptions for the appropriate cycles in this manual should be used to parameterize the
individual measuring versions.
3.4.2

Measuring a workpiece on a turning/milling machine

The following section refers to the workpiece measuring on turning/milling machines. Whereby
turning is set up as the 1st technology and milling as the 2nd technology.
- Turning measurement (measure diameter, outside, inside, etc.)
If measuring is to be performed in different tool orientations (B axis for turning technology), the
probe can be prepositioned with the "Tool alignment" function (
250
CYCLE800 ).
