Fixed Calibration
Fixed calibration refers to the calibration operation on a certain fixed position of machine tool due to
tool damage or other causes, frequently used in multi-tool mode. The length of tool and the clamping
position may vary, thus tool offset should be reconfirmed by fixed calibration and the sketch map of fixed
calibration is shown in Fig. 3-18.

Fig. 3-18 The process of fixed calibration
The process of fixed calibration refers to input of the D-value of the recorded machine coordinate of
tool nose when reaching the tool presetter surface subtracting the thickness o
f tool presetter into ―tool
offset‖.
Tool offset= Machine coordinate

The steps of fixed calibration are as below:
1) Select tool according to tool No.;
2) Execute fixed calibration to the selected tool and record the tool offset;
3) Execute step 1 and 2 to each tool;
4) Select any tool to move to workpiece surface for clearing.
