Remarks
Several entry components are available for geometric variables (e.g. length 1 or radius). These
are added together to produce a value (e.g. total length 1, total radius), which is then used for
the calculations.
Offset values not required must be assigned the value zero.
Tool parameters $TC-DP1 to $TC-DP23 with contour tools
Note
The tool parameters not listed in the table, such as $TC_DP7, are not evaluated, i.e. their
content is meaningless.
