Paraxial tool orientation

2.12.1

Basic tool orientation

The basic tool orientation results from the active machining plane:
Working plane
G17 (X/Y)
G18 (Z/X)
G19 (Y/Z)
2.12.2

Tool orientation for plane change

A setting in the setting data determines how the tool orientation changes when the machining
plane is changed.
● SD42954 $SC_TOOL_ORI_CONST_M (for milling/special tools)
● SD42956 $SC_TOOL_ORI_CONST_T (for turning/grinding tools)

Assignment of the tool length components
Activates setting data SD42942 $SC_TOOL_LENGTH_CONST_T.
With this setting, it is possible to define the assignment of the tool length compo‐
nents that is effective on a machining plane change (Page 171) separately for
milling/special tools and turning/grinding tools:
SD42940
$SC_TOOL_LENGTH_CONST
SD42942
$SC_TOOL_LENGTH_CONST_T
Example:
SD42940 $SC_TOOL_LENGTH_CONST = 17
SD42942 $SC_TOOL_LENGTH_CONST_T = 18
Tool length compensations for milling/special tools take effect in plane G17; length
compensations for turning/grinding tools take effect in plane G18.
As for SD42950 = 0.
