Angled-Wheel Grinding
Chapter 14
14-14
This section covers features or considerations that must be taken into
account when jogging an angled-wheel grinder. For details on using the
jogging features refer to the manual motion sections starting on page 4-1.
All manual motions use normal angled-wheel positioning method (G16.3)
regardless of the current angled-wheel mode. Two step positioning is not
available in manual mode. G16.4 mode uses the G16.3 type of positioning
for manual motions.
Important: The PAL axis mover feature is not available to move the X
virtual axis in any grinding mode. Refer to your system installers
documentation for details on features that use the PAL axis mover on your
control.
Normal single axis jogs
In angled-wheel mode (G16.3 or G16.4 active) the operator can jog either
the real W or Z axes, or the virtual X axis. Restrictions apply to jogging
multiple axes (see below).
When not in angled-wheel mode, the virtual X axis does not exist. This
means manual X axis moves can not be performed while in G15 mode.
If a rotary axis is used to specify the wheel axis angle, you can not jog this
rotary axis while in angled-wheel mode. You can however home the rotary
axis while in angled-wheel mode.
Multiple axis jogs including Arbitrary Angle jogs
In angled-wheel mode (G16.3 or G16.4 active) jogs that request multiple
axes are not permitted. You can only request a jog on X, Z, or W one axis
at a time. Requests to perform the following multiple axis jogs are not
permitted in angled-wheel mode:
X and Z together
X and W together
W and Z together
X axis jogs are not considered a multiple axis jog even though X axis
moves position W and Z together.
Note that X axis jogs will position both Z and W axes simultaneous in
G16.3 mode and G16.4 mode.
