6.38. G96. CONSTANT SURFACE SPEED

When G96 is programmed, the CNC assumes that values F refer to the feed at the tool’s
cutting edge. The feed at the center of the tool will vary when machining around corners
so that the feed at the cutting edge remains constant.

This feature enables a better finishing of the part especially on inside corners. G96 is
modal and is cancelled by G97,M02 or M30.

When operating in G96 the tool center’s speed will varyaround corners, so that the cutting
edge’s speed remains constant.

6.39. G97. CONSTANT TOOL CENTER SPEED

When G97 is programmed the values F4 and F3.4 are assumed as being the feed at the
tool’s center. The feed at the cutting edge will vary when machining around corners so that
the feed at the center of the tool remains constant.

Function G97 is modal and incompatible with G96. The CNC assumes G97 when turning
ON and after M02,M30, EMERGENCY or RESET.
