Graphics
Graphics can be configured to plot the X (virtual) as well as the W (wheel
axis) in any angled-wheel grinding mode (G15, G16.3 or G16.4). No
motion will appear on the graph for the X axis in the G15 mode. Plots of
the wheel axis are orthogonal regardless of your current wheel axis angle.
This can cause graphics to show an part contour not representative of the
actual wheel path relative to the part.
