Dist. tool tip – center of rot.

(incremental): The TNC tilts the

tool (or table) relative to the tool tip. The DIST parameter shifts the

center of rotation of the positioning movement relative to the

current position of the tool tip.

Feed rate? F=

: Contour speed at which the tool should be

positioned

Retraction length in the tool axis?

: Retraction path MB is

effective incrementally from the current tool position in the active

tool axis direction that the TNC approaches before tilting. MB MAX

positions the tool just before the software limit switch.

If the tool is already at the given distance to the

workpiece before positioning, then relatively speaking

the tool is at the same position after positioning (see

figure at center right,

= DIST)

If the tool is not at the given distance to the workpiece

before positioning, then relatively speaking the tool is

offset from the original position after positioning (see

figure at bottom right,

= DIST)
