This example uses the same information, with
corrections for positive and negative values, as
used in the manual.
Refer to
while reviewing the example's list
Figure 2
of parameters below.
1.
The XZ plane is chosen for this example.
Coordinate motion will have negative values
for X and Z during the cutting operation.
2.
The center of the radius is assigned to X-20
and Z-20.
3.
The Start Point is defined as X-20 and Z0.
4.
The End Point is defined as X-40 and Z-20.
5.
The Tool Diameter will be 6mm.
6.
Tool Compensation will be assigned a posi-
tive value, giving the radius a convex shape.
We recommend before actually machining any
part that the corner be removed, if possible, to
help minimize the depth of cut. Otherwise, the
step over rate will have to be greatly reduced for
safety, slowing the production rate.
To machine a radius in the XZ plane using the
R function, do these steps:
1.
Move the milling table so the center of the
spindle is located at the Zero Position indicat-
ed in
X and Y. Mount the 6mm ball
Figure 2 in
end mill into the spindle and touch off. Reset
zero in all axes for both ABS and INC.
2.
Move the table until the DRO reads X20, Y4
and Z0.
3.
Press the R function key.
4.
Refer to
Figure 3 and
work plane XZ. You can toggle
through the choices by pres-
sing the Next key.
5.
Press the Enter key when XZ
is displayed on the DRO.
