The following sequence of operations is strongly recommended for setting up this machine:
1. Load a program into memory. This is either manually entered or downloaded from a CAM
package via the RS-232 interface.
2. Determine the tools needed and get them ready.
NOTE:
If machine is equipped with the optional
extended Z-clearance table
,
follow these guidelines:
Avoid extreme loads on the center of table or far end of table. The weight
of the part should be distributed evenly over the table or one pad.
Flatness of part should be within 0.002".
3. Use a vise or fixture to hold the part and mount it on the mill.
4. Locate the
X
and
Y
zero points of your program on the part. Usually these points will coincide with
the print reference point where dimensioning begins, which needs to be clearly indicated by the
programmer. Use an edge finder or indicator to locate this point with the handle function. After
locating the programmed zero point, push the display offset key and page down until the work zero
offset page appears. Cursor down to G54
X
, the work zero offset. Push the PART ZERO SET
button and the
X
-axis machine value will be stored at this location. Cursor to the G54
Y
location
and repeat the above. You have now told the machine where part zero is located. Usually
Z
and
A
values will not have to be set and should be zero.
5. Remove any tools from the changer and MDI a T1 M6 command to install tool #1 into the spindle
(it should be empty). Put your tool #1 into the spindle using the TOOL RELEASE button. Push the
OFSET key and page down to get to the tool offset page and cursor to tool #1. Do not install any
tools directly into the carousel. Use MDI or ATC FWD/REV to retrieve tools.
6. Push the Z-JOG key until you are close to the top of your part. (The top of your part should be Z0).
Use the Handle to accurately position the tool edge to Z0. Push the TOOL OFSET MESUR key
and the
Z
machine value will be stored in tool offset #1. Note that this automatic offset measure-
ment works with G43 only and the work
Z
offset must be zero.
7. Push the NEXT TOOL key and the Z-axis will retract to tool change position and tool #2 (empty)
will be installed in the spindle. Put your tool #2 into the spindle and jog to
Z
zero as you did for
tool #1. The cursor will automatically be on offset #2. Push TOOL OFSET MESUR.
8. Repeat this procedure until all tools are measured and installed.
9. MDI a T1 M6 to return to tool #1.
10. You are now ready to run your program.
11. Please note that in order to load and measure all of your tools, you do not need to use any keys
other than JOG, TOOL OFSET MESUR, and NEXT TOOL. Also note that this automatic offset
measurement works with G43 only.
