Angled-Wheel Grinding
Chapter 14
14-16
When angled-wheel mode is exited either:
the plane that was active prior to entering angled-wheel mode is
re-established
or
if a plane select G code is programmed in the G15 block, that plane
becomes active.
Read this section if you are using wheel length and radius offsets, and
work coordinate system offsets on an angled-wheel grinder.
Upon entry into one of the angled wheel modes the control cancels all
active offsets. Offsets are not canceled when you change between G16.3
and G16.4 mode as long as angled wheel mode is not exited with a G15.
When using the automatic offset table backup features the control inserts a
G16.3 block as the first block in the G10 program. This block is always
inserted when an offset table is backed up on an angled wheel grinder
regardless of the current angled wheel mode. This allows the control to
restore X axis offsets when the backup program is executed later. This can
change the angled-wheel mode of your machine if the control is not
configured to reset to default G codes when an M30 end of program is
executed or if the default G codes is not the mode you were in when you
began executing the G10 program.
Offset table values can be manually changed (using the softkeys) for all
axes in and out of angled wheel mode (G15, G16.3, and G16.4). When
programming a G10 block in your own part program:
in G15 mode any virtual axis (X) values programmed are not entered
into the offset table.
in angled wheel mode (G16.3 and G16.4) all axis values (including the
virtual axis X and wheel axis W) programmed in the G10 block are
entered into the offset table.
