OPERATION
3.9 SETUP P ROCEDURES
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.
CAUTION!
If machine is equipped with the optional 50 taper spindle, follow
these guidelines:
îš• 25 lb. maximum per tool, and 300 lb. maximum total tool weight.
îš• Extremely heavy tool weights should be distributed evenly.
If machine is equipped with the 20 or 32 pocket tool changer, follow
these guidelines:
îš• 12 lb. maximum per tool (200 lb. maximum total tool weight for 32
pocket tool changer).
îš• Extremely heavy tool weights should be distributed evenly.
îš• Ensure there is adequate clearance between tools in the tool
changer before running an automatic operation. This distance is
3.6" for 20 pocket, and is 3.4" for 32 pocket.
Note: If machine is equipped with the optional extended Z-clearance table,
follow these guidelines:
îš• Avoid extreme loads on center of table or far end of table. Weight of part
should be distributed evenly over the table or one pad.
îš• Flatness of part should be within .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 and 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 changer and MDI a T1 M6 command to install tool #1 into 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 mea-
surement works with G43 only and the work Z offset must be zero.
