14) Make the tool to cut on Surface A1;
15) Retract the tool along X axis without Z axis moving and stop the spindle; measure the
distance "β1" between the Surface A1 and the workpiece coordinate system origin
(supposing β1=1) ;
16) Press key to enter the Offset interface, select the TOOL OFFSET window, then move
the cursor by pressing , to select the corresponding offset number;
17) Key in by sequence the address key , sign key , number key , and
key to set Z offset value;
18) Make the tool to cut on Surface B1;
19) Retract the tool along Z axis without the movement of X axis, and stop the spindle;
20) Measure the distance "α1" (supposing α1=10);
21) Press key to enter the Offset interface, select the TOOL OFFSET window, then move
the cursor by pressing , key to select the corresponding offset number;
22) Key in by sequence the address key , number key , and key to set
X offset value;
23) Move the tool to a safety position;
24) Repeat the execution from Step 12 to Step 23 to perform the toolsetting operation for
other
tools.
Note 1: Machine zero switch must be fixed for the toolsetting operation by machine zero return.
Note 2: The workpiece coordinate system setting can’t be done by G50 code after toolsetting by
machine
zero return.
Note 3: The tool compensation should be done by coordinate offset by the CNC system (the
system
parameter No.003 Bit4 is set to 1), further more, the tool lengths compensation should be
performed
by using the T code in the 1st block, or the 1st move block should contain the T code for the tool
length compensation.
Note 4: The corresponding parameters should be set as follows:
Bit7=0 of the system parameter No.004;
Bit5=1 of the system parameter No.012;
Bit7=1 of the system parameter No.012.
Note 5: The setting values of the system parameter No.047 should be close to the absolute
coordinate
values of machine zero in workpiece coordinate system XOZ, as is shown in the following figure:
As shown below:
Example: After machine zero returning, when the absolute coordinate of the tool in
