2 - 170 Conversational Part Programming v546CO WinMax Lathe Conversational Part Programming
• SURFACE CLEARANCE—sets the distance above the Z (Axial) or X (Radial)
start point for the tool to move between passes to allow for rapid motions
back to the start point for the next pass.
This setting also applies when rapid motions are made to position for cutting
depths after the first depth.
Example:
In this example, the Z motion would be:
Surface Clearance = 1.27 mm (0.0500 in)
Z Start = 2.54 mm (0.1000 in)
Peck Depth = 5.08 mm (0.2000 in)
1. Rapid to 3.81 mm (0.15 in)
(Z Start + Surface Clearance)
2. Feed to -2.54 mm (-0.1 in) to machine first pass.
3. Rapid back to 3.81 mm (0.15 in)
(Z Start + Surface Clearance)
4. Rapid to -1.27 mm (-0.05 in) (Depth of Previous pass + Surface Clearance)
5. Feed to -7.62 mm (-0.30 in) to machine second pass.
6. Rapid back to 3.81 mm (0.15 in)
(Z Start + Surface Clearance)
7. Rapid to -6.35 mm (-0.25 in)
(Depth of Previous pass + Surface Clearance)
8. Feed to -12.7 mm (-0.5 in) to machine third pass.
9. Rapid back to 3.81 mm (0.15 in) (Z Start + Surface Clearance)
10.Repeat to final depth.
