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.
