Part 5 Offset Adjustment for the Y-axis and Z-axis Origin Points
5-3. How to Adjust the Center-Y Offset
To adjust the offset, you perform actual cutting of material and evaluate the amount of misalignment.
There are no special rules about the particular cutting you should use. This section explains a simple method that lets you perform cutting
without using any software. We recommend using modeling wax or chemical wood as the workpiece with this method.
Running [Y CENTER MODE] initializes the [CENTER-Y OFFSET] value to zero.
1
Run [Y CENTER MODE]. For more information, see "3-
3. Setting the Y- and Z- axis Origin Point at the A-axis
Center of Rotation."
When you have finished, install a square end mill having
sufficient blade length (at least one-half of the thickness
of the workpiece).
2
Load a box-shaped workpiece, then set the A-axis origin
point at a place where the surface is level. Hold down the
[JOG] key for 0.5 seconds or longer to return the [
[
] keys to Y-axis operation.
For more information, refer to "3-1. Rotating the A Axis
Using the Operation Panel" and "3-2. Setting the A-axis
Origin Point."
3
Hold down the [SPINDLE] key for 0.5 seconds or longer
to rotate the spindle. Press the [JOG] key to line up the [*]
with the spindle speed, then use the dial to make the set-
ting for about 8,000 to 10,000 rpm.
4
Move the tool to the far (back) side of the workpiece and
lower the tool by about half the thickness of the workpiece.
Use the [
] key and the dial to gradually approach the
workpiece and perform 0.2 to 0.5 mm of cutting-in. Make
a note of the Y-axis coordinate value that appears on the
display at this time.
5
Press the [JOG] key to line up the [*] with the X axis. Turn
the dial to cut a width of about 2 to 3 cm (1 in.).
