In certain instances, dresser/wheel radius compensation creates a
non-programmed move called a generated block. These blocks improve
cycle time and corner-cutting quality.
Dresser/wheel radius compensation generates blocks for type A or B
moves as follows:
Type ofMove Type A Type B
Entry Move No block is generated Blockis generated
Dresser/Wheel Path Blockis generated Blockisgenerated
Exit Move No block is generated Blockis generated
Important: These blocks are created only if:
G41 is active and you program an inside angle that is less than 90
°
G42 is active and you program an outside angle that is more than 270°
