Measurement (M5)

13.1

Brief description

Channel-specific measuring
A measurement mode is programmed in a part program block (with or without DDTG). A
trigger event (edge of the probe) is defined additionally, which will trigger the measurement
process. The instructions apply to all axes programmed in this particular block. The program
with the measurement process in AUTOMATIC mode is executed and can be employed for
workpiece or tool measuring.
Tool measuring in JOG
SINUMERIK 802D includes operator support for the measurement process in JOG mode
specially for measuring tools on lathes and milling machines. Channel-specific measuring is
integrated into this sequence. The PLC user program must include the required functionality.
The measured offset values of the tool are available in the tool offset memory at the end of
the measuring sequence.
The exact operating instructions are contained in:

Probes that can be used

General
In order to measure tool and workpiece dimensions, a touch-trigger probe is required that
supplies a constant signal (rather than a pulse) when deflected.
The probe must operate virtually bounce-free. Most sensors can be adjusted mechanically to
ensure that they operate in this manner.
Different types of probes supplied by a variety of manufacturers are available on the market.
Probes are therefore divided into three groups according to the number of directions in which
they can be deflected (see figure below).
