Linear Pattern - HEIDENHAIN POSITIP 880 User Manual

2nd step: Drill
Move to hole:
Traverse each coordinate of the working plane to
display value zero.
Drill:
Traverse to display value zero in the tool axis. When
you have reached required depth, it will automatically
advance to the coordinates of the next hole.
After drilling, retract the drill in tool axis.
Press the NEXT HOLE soft key.
Continue to drill the remaining holes in the same way.
When pattern is complete, press the END soft key.

Linear Pattern

Information required:
First hole (1st hole of the pattern)
Holes per row (number of holes in each row of pattern
Hole spacing (the spacing or offset between each hole in the row)
Angle (the angle or rotation of the pattern)
Depth (the target depth for drilling in the tool axis)
Number of rows (number of rows in the pattern)
Row spacing (the spacing between each row of the pattern)
POSITIP 880 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 graphic enables verification of the hole pattern before you start
machining. It is also useful when:
selecting holes directly
executing holes separately
skipping holes
