Wheel LengthOffsets
When wheel length offsets are entered into the offset table both the
X(virtual) and W(real) axes allow entry. When a wheel length offset i s
activated the control selects the offset value out of the offset table as
follows:
inAngled-WheelMode:
(G16.3 or G16.4)
XandZ offsetsare used
not in Angled-WheelMode:
(G15)
W and Z offsetsareused
If a wheel length offset is activated manually (through the use of the
{ACTIVE OFFSET} softkey), the wheel length offset will be activated in
the normal angled wheel mode (G16.3).
Important: If you are using either the G89 or G89. 1 cycles the active tool
offset when a micro-feed is aborted has special constraints. Refer to page
17-40 for details.
Work Coordinate System Offsets
When work coordinate system offsets are entered into the offset table both
the X(virtual) and W(real) axes allow entry. When the control activat es a
work coordinate system, i t selects the coordinate offset values out of the
offset tables as follows:
InAngled-WheelMode:
(G16.3 or G16.4)
XandZ offsetsare used
Notin Angled-WheelMode:
(G15)
W and Z offsetsareused
This section covers features or considerations that must be taken into
account when using s oftware overtravels, and programmable zones with an
angled-wheel grinder.
Software Overtravels
For details on what software overtravels are and how they work refer to
page 11-34. The system installer determines the location and operation of
the software overtravels. Since the X axis is a virtual axis, no software
overtravels are available to monitor t he X axis. Software overtravel are
available that monitor the W and Z axis positions.
