Further information
Tool type
The tool type (tool parameter $TC_DP1) is evaluated. Only milling tools with cylindrical shank
(cylinder or end mill, toroidal miller and, in the limit case, cylindrical die mill) are permitted. This
corresponds to the tool types 1 - 399, with the exception of the numbers 111 and 155 to 157.
Standard tools with corner rounding
Corner rounding with a standard tool is defined by the tool parameter $TC_DP7. Tool
parameter $TC_DP16 describes the deviation of the corner rounding of the real tool compared
with the standard tool.

W5: 3D tool radius compensation
Comment
; Cylindrical milling tool
; Activation of the transformation.
; Definition of the surface normal of the
limitation surface at the start of the
block.
; Activate 3D circumferential milling,
taking into account the limitation sur-
face + switching off collision detection.
; Obtuse angle ==> no infeed
; Acute angle ==> infeed
; Movement in the tool direction.
; Pure change in orientation.
; Change of the surface.
; Deactivation of the tool radius compen-
sation.
