Common Causes

• Starting point coordinates lie within or on the boundary of the CYCLE95 contour rectangle instead of outside it
• Incorrect G0 rapid positioning command before CYCLE95 call places tool inside the defined contour area
• Contour subroutine parameters define a smaller rectangle than intended, causing valid starting points to fall inside
• Tool offset or work offset not properly accounted for when calculating starting point position relative to contour

Troubleshooting Steps

1. 1Verify the starting point coordinates in the NC program immediately before the CYCLE95 call; confirm point is geometrically outside the contour rectangle on all axes
2. 2Review the contour subroutine parameters passed to CYCLE95 (corner points, rectangle dimensions) to ensure they define the correct work area boundaries
3. 3Check active G54-G59 work offset and tool offset values; recalculate starting point in machine coordinates to confirm it lies outside the contour
4. 4Add a G0 positioning block to move the tool to a known safe point outside the contour rectangle before calling CYCLE95; verify clearance on all sides
5. 5Simulate the program in the CNC's simulation or graphics mode to visually confirm starting point location relative to the contour; adjust coordinates as needed
