Multiple Holder, Extension and Shank Stages Note:
In the current version of Cimatron, it is possible to define up to ten holder stages, up to ten extension stages and two shank stages. Shank2 and extensions are also considered as holders and use the holder dimension variables. If the total number of the above is greater than ten, the actual 10th stage will be output using the EXTH_...01 variables sets. All of the stages beyond ten, will be output using the EXTH_...02 to 11 variables sets.
For backward compatibility, since only ten holder stages were supported in the past, a combined size of the 10th holder stage and beyond can be output using the EXTH_...00 variables set.
Backward Compatibility Note: In GPP2, the NEXT_TOOL and NEXT_NAME variables are not used. Instead, all parameters of the next tool are available through the next tool function. See GPP2 Language Reference Manual for details.
Spindle Variables Note: The spindle variables SPNDL_BOT, SPNDL_CON, SPNDL_TOP, SPNDL_TOT receive the following values:
-
If there is no spindle – all variables are zero.
-
If there is only one stage – the values are equal to those of the first stage.
-
In the case of multi-stages:
-
SPNDL_BOT and the SPNDL_TOP receive the maximum value of SPNDL_TOP0 - SPNDL_TOP9.
-
SPNDL_CON is zero.
-
SPNDL_TOT receives the sum of SPNDL_TOT0 - SPNDL_TOT9.
