graphic for linear hole pattern
Linear hole patterns
Information required:
• Coordinates of the first hole
• Number of holes per row
• Spacing between holes on a row
• Angle between the first row and the X axis
• Number of rows
• Spacing between rows
POSITIP calculates the coordinates of the holes which you then
move to simply by traversing to display value zero.
The graphic positioning aid is available for all moving axes. The po-
sitioning aid frame for the tool axis is dashed.
The graphic enables verification of the hole pattern before you start
machining. It is also useful when:
• selecting holes directly
• executing holes separately
• skipping holes
