Programming the tool orientation with LEAD= and TILT=
The resultant tool orientation is determined from:
● Path tangent
● Surface normal vector
at the start of the block
A4, B4, C4 and at the end of the block A5, B6, C5
● Lead angle
LEAD
in the plane defined by the path tangent and surface normal vector
● Tilt angle
TILT at the end of the block
vertical to the path tangent and relative to the surface normal vector
Behavior at inside corners (for 3D-tool compensation)
If the block is shortened at an inside corner, the resulting tool orientation is also achieved at
the end of the block.
