18.6 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 "Differences between Cycles 31 to 33 and Cycles 481 to
483", page 385). This cycle is particularly suitable for the first
measurement of tools, as it saves time when compared with
individual measurement of length and radius. Via 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
in the tool table the number of teeth
CUT as 0 and
adjust machine parameter
CfgToolMeasurement.
Refer to your machine manual.
