Dresser/Wheel Radius Compensation

Chapter 15

15-16

You can program the generated block between the two dresser/wheel paths

as linear or circular with these G-codes:

G39(or G39.1);

Where: Causes:

G39

linear transition blocks. If you programa G39 or G39.1,G39 isthe

default(established atcontrol resetor end ofprogramcommand).

This command is modal.

G39.1

circular transition blocks. When programming straight line-to-arc or

arc-to-straightline moves,thegenerated blockis always linear,and

thecontrolignoresthe G39.1. This commandismodal.

You can program a G39 or G39.1 in any block. However, you must

program them in or before the block that causes a dresser/wheel radius

compensation generated block.

Important: For linear generated blocks only, your system installer can

define a minimum block length in AMP. If the generated move length is

less than the system-defined minimum block length, no generated block is

created and the dresser/wheel path proceeds to the intersection of the two

compensated paths. If the generated move length i s equal to or greater

than the system-defined minimum block length, a generated block is

created.

Throughout this chapter, we show drawings where a generated block is

created. Both G39 and G39.1 are shown in these drawings where

applicable.
