Skew Compensation (Milling applications only)
Skew compensation allows the user to drill holes on a workpiece
without aligning the workpiece on the machine. Use this feature only
for drilling holes.
The Skew Compensation setup form is found under Job Setup. The
form is used to turn skew compensation on, or off; to set, or learn the
skew angle; and to set the datum.
8 In the Status Field, press the ON/OFF soft key, turn skew
compensation on, or off.
8 In the Angle Field, enter the skew angle if known. To learn the
angle, use the edge finder (or a tool) to touch off the part.
8 When using a tool, touch the tool to the edge of the part, and press
the TEACH soft key.
Setting the datum
„ After learning the angle, the datum may be set to the corner of the
part by touching off one point along the other side see "Datum
Soft Key" on page 28. In the datum calculation, the system
compensates for the radius of the edge finder (or current tool).
The readout automatically compensates for the misaligned workpiece
on the machine when running a program, a hole pattern, or preset.
Move the machine until the X axis and the Y axis indicate zero.
Pressing the Decimal key while in operating mode, will also
stop and start the clock. Pressing the Zero key will reset
the clock.
The skew angle is learned by touching off two points along
one side. When using the edge finder, the location of the
edge is captured automatically.
When skew compensation is activated, the skew icon is
displayed on the right side of the axis display.
