Jog the tool up, away from the surface of the workpiece. When you are a small distance away from the
workpiece, switch to continuous movements and move the tool about 1 inch above the workpiece.
11.
Hold the piece of paper against the front of the workpiece.
12.
Carefully jog the tool along the Y-axis until it is about 0.5 inches in front of the workpiece.
13.
Jog the tool down the Z-axis until about half the length of cut is alongside the front of the workpiece.
14.
Switch to the slowest speed and
0.01 inch steps
, and jog the tool closer to the paper. Stop when you are
just next to the paper.
15.
When you are just next to the paper, switch to
0.001 inch steps
. Carefully jog the tool back until the
cutting edge just pinches the paper. Check this point by trying to move the paper after each step. When
you can no longer move the paper, you have reached the position.
16.
Select
Set Position
from the Setup menu. The Set Position dialog box is displayed.
17.
In the Y field, enter the coordinate of the current position on the Y-axis
: -0.0625
, and click
OK
.
Hint: Enter
-0.125/2
. The system will automatically calculate half the diameter of the tool as -0.0625.
18.
Verify in the Machine Info window that the Y value reads -0.0625 inches.
19.
You will now touch off the left of the stock (X = 0).
Switch to continuous movements and jog the tool straight up the Z-axis until the tool is 0.5 inches above
the workpiece.
20.
Hold the piece of paper against the left side of the workpiece.
21.
Carefully jog the tool until it is about 0.5 inches to the left of the workpiece.
22.
Jog the tool down until about half the length of cut is alongside the workpiece.
23.
Switch to
0.01 inch steps
, and slow movements, and jog the tool closer to the paper. Stop when you are
just next to the paper.
24.
When you are just next to the paper, switch to
0.001 inch steps
. Carefully jog the tool back until the
cutting edge just pinches the paper. Check this point by trying to move the paper after each step. When
you can no longer move the paper, you have reached the position.
25.
Select
Set Position
from the Setup menu. The Setup dialog box is displayed.
26.
In the X field, enter the coordinate of the current position on the X-axis:
-0.0625
, and click
OK
.
Hint: Enter
-0.125/2
. The system will automatically calculate half the diameter of the tool as -0.0625.
27.
Verify in the Machine Info window that the X value reads -0.0625 inches.
The machining axes are now defined.
28.
Jog the tool up and away from the workpiece.
