2 - 20 Conversational Part Programming v546CO WinMax Lathe Conversational Part Programming
• ELEMENT TOLERANCE—identifies the amount of adjustment allowed if two
elements of a profile fail to meet or intersect. If this occurs, the elements can
be joined automatically if the required length is within this amount. The
default value is 0.00254 mm (0.0001 in.). The maximum value is 0.0254 mm
(0.001 in.). This field is not available when No is selected in the OVERRIDE
TOLERANCE field.
Groove Rough Operation
A rule to follow when programming a Groove Rough operation is that the first element
and the last element must be parallel. It is also recommended to have the first and last
elements start and end at the same Diameter (or Radius) or Z location.
The following fields appear when Groove Rough is selected in the Operation field:

• STEP OVER—identifies the distance the tool steps over each pass between
grooving passes. This field appears when Groove Rough is selected for the
Operation.
• CUT CLEARANCE—identifies the amount of clearance above the groove for
cutting each profile, shown as 1 in the figure below. The default is 1.27 mm
or 0.05 inch. This field appears when Groove Rough or Groove Finish is
selected for the Operation.
• RETRACT ANGLE—pulls the tool off the profile between steps along a vector
in the direction of retract angle, shown as 2 in the figure below, if NO is
selected for RETRACT ALONG PROFILE. The default is 45°. This field appears
for all rough and finish operations.
Refer to Figure 2–17. Sample OD Operation Elements, on page 2 -
27 for an example of a Turn Element.
