19.5 Measuring Tool Length and
Radius (Cycle 33 or 483,
DIN/ISO: G483)
Cycle run
To measure both the length and radius of a tool, program the
measuring cycle TCH PROBE 33 or TCH PROBE 482 (see also
"Differences between Cycles 31 to 33 and Cycles 481 to 483" on page
441). This cycle is particularly suitable for the first measurement of
tools, as it saves time when compared with individual measurement
of length and radius. In input parameters you can select the desired
type of measurement:
„ Measuring the tool while it is rotating.
„ Measuring the tool while it is rotating and subsequently measuring
the individual teeth.
The TNC measures the tool in a fixed programmed sequence. First it
measures the tool radius, then the tool length. The sequence of
measurement is the same as for measuring cycles 31 and 32.
Please note while programming:
Before measuring a tool for the first time, enter the
following data on the tool into the tool table TOOL.T: the
approximate radius, the approximate length, the number
of teeth, and the cutting direction.
Cylindrical tools with diamond surfaces can be measured
with stationary spindle. To do so, define the number of
teeth (CUT) with 0 in the tool table and adjust the machine
parameter CfgToolMeasurement. Refer to your machine
manual.
