Dresser/Wheel Radius Compensation

Chapter 15

15-32

If the number of non-motion blocks in t he compensation mode has not

exceeded a value selected by your system installer in AMP, all of the

program blocks in Example 15.7 produce the same exit move.

The exit of the dresser/wheel for type B radius compensation takes the

shortest possible path to the end-point of the exit move for inside corners

only. For outside corners, the dresser/wheel always remains at least the

radius of the dresser/ wheel away from the end-point of the last move in

compensation. You can redefine the start-point using an I and/or K word

as described in t his section later. The end-point of the exit move is no

longer offset to the left or right.

Figure 15.25 and Figure 15.26 show examples of typical exit moves using

type B radius compensation. All examples assume the number of

non-motion blocks before the designation of the G40 command has not

exceeded the number allowed as determined by your system installer in

AMP.
