TOMATECH AUTOMATION
only needs to be set again, and a machine zero return should be done before the
toolsetting. The
machining could be continued by performing a machine zero return at power on after
power-off, which
is very convenient for the operation.

1) Press key to enter Machine Zero mode, move axes to machine zero;
2) Select a tool by random and set the offset number of the tool to 00 (e.g. T0100,
T0300) ;
3) Make the tool to cut on Surface A;
4) Retract the tool along X axis without the movement of Z axis, and stop the spindle;
directly
press , and the CNC records the absolute values of the position, at the moment,
directly move the tool;
5) 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;
6) Key in by sequence the address key , number key and key to set the
offset value of Z axis;
7) Make the tool cut along Surface B;
8) Retract the tool along Z axis without the movement of X axis, and stop the spindle;
9) Measure the distance "α"(supposing α=15);
10) Press key to enter the Offset interface, select the TOOL OFFSET window, then move
the cursor by pressing , to select the corresponding offset number;
11) Key in by sequence the address key , number key , and key to set
the offset value of X axis;
12) Move the tool to a safety height for tool change;
13) Change for another tool, and set the tool offset number to 00 (i.e. T0100, T0300);
