HEIDENHAIN iTNC 530 507
12.3 The PLANE function: Tilting the working plane (software option 1)
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, 1 = 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, 1 = DIST)
