Setting Tool Length Offset
The point where the tools will be set, is called a gauge point. This is a
common starting position for all the tools. This is where the programmer
has established the Z axis zero position for the part program (not to be
confused with Z zero at the MCS position).
To set the TLO (Tool Length Offset) manually:
1) Locate all tools specified for the program and load the tools into
tool holders. Place the holders close to the machine. Place the
machine in the Manual Mode.
2) Load tool #1 into the spindle using the TOOL IN/OUT button.
3) Place a gauge block, of any available size, on top of the part.
4) Press the MPG button and use the Manual Pulse Generator to
jog the Z axis until the tip of the tool is just above the top of the
gauge block. Select smaller increments for jog, and jog the tool
down until the tip of the tool is close enough to the gauge block
for the desired tool length offset.
5) Remove the block from under the tool.
6) Press the Position soft key to return to the Main Manual screen.
7) Press the Measure Tool soft key.
8) Press the Length Manual soft key.
9) Use the cursor keypad arrows, cursor down to highlight Z0
_________ ABS.
10) Type in the gauge amount (tool block size).
11) Press the Set Length soft key button.
This inputs the tool length based on the current Z axis location into the
tool table:
