Move the tool to a proper height (higher than the tool alignment instrument) and press the 【Start tool
alignment】 key to execute the automatic tool alignment procedure. The system will fill in coordinate system 00
with the tool length compensation value after completing automatic tool alignment.
Set "Gap setting for the work coordinate system": Move the cursor to the "Work coordinate system" field, enter a
numerical value (from 54 to 59) in the input area and press the <Input> key. If the extended coordinate system
G54 is being used, the "Work coordinate system" field should be set as G54 before moving the cursor to the next
field (extended coordinate system), enter a numerical value (1 to 100) in the input area and pressing the <Input>
key.
Switch to hand wheel mode (MPG), move the tool to a position above the workpiece such that the tool tip is just
touching the surface of workpiece, and then press the 【Z gap】 key to set the gap value into the designated
coordinate system.
Note: The approach for setting the gap of each workpiece is as shown below:
For example: There are two workpieces; one is based on the G55 coordinate system (workpiece A) and the other is based
on the G54P100 coordinate system (Workpiece B)
Set the gap value for workpiece A:
i. Move the cursor to the "Work coordinate system" field, enter the value 55 in the input area and press the
<Input> key.
ii. Switch to hand wheel mode (MPG), move the tool to the position above workpiece A such that the tool
tip is just touching the surface of workpiece, and then press the 【Z gap】 key to set the gap value into the
G55 coordinate system.
Set the gap value for workpiece B:
i. Move the cursor to the "Work coordinate system" field, enter the value 54 in the input area and press the
<Input> key.
ii. Move the cursor to the next field (extended coordinate system), enter the value 100 in the input area and
press the <Input> key.
iii. Switch to hand wheel mode (MPG), move the tool to the position above workpiece B such that the tool
tip is just touching the surface of workpiece, and then press the 【Z gap】 key to set the gap value into the
G54P100 coordinate system.
《Multiple tools/multiple workpieces》
For the multiple tools/multiple workpieces method, the tool length of automatic tool alignment will be saved into Z length
offset of the tool length offset number corresponding to the tool, and the gap value between the tool alignment
instrument and workpiece surface should be saved into the designated work coordinate system in accordance with Z axis
gap settings. The operation is described below:
