How to set your tool in CNC manufacturing? Here are some steps for CNC tool setting.

(1) Tool setting in X and Y directions
① When the workpiece is clamped on the worktable of the machine tool, the measuring position of the edge finder should be reserved on the four sides of the workpiece.
② Quickly move the worktable and spindle to make the edge finder probe close to the left side of the workpiece;
③ Use fine adjustment operation, let the probe touch the left side of the workpiece slowly until the edge finder lights up, and record the X coordinate value in the machine coordinate system at this time, such as -310.300;
④ Lift the edge finder to the upper surface of the workpiece, quickly move the worktable and spindle, and make the probe close to the right side of the workpiece;
⑤ Use fine adjustment operation, let the probe slowly touch the left side of the workpiece until the edge finder lights up, and record the X coordinate value in the mechanical coordinate system at this time, such as -200.300;
⑥ If the diameter of the probe is 10 mm, the length of the workpiece is - 200.300 - (- 310.300) - 10 = 100. According to this, the X coordinate value of the origin of the workpiece coordinate system w in the machine coordinate system is - 310.300 + 100 / 2 + 5 = - 255.300;
⑦ Similarly, the Y coordinate value of the origin w of the workpiece coordinate system in the mechanical coordinate system can be measured.
(2) Tool setting in Z direction
① Remove the edge finder and install the tool used in machining onto the spindle;
② Place the z-axis setter (or tool setting block with fixed height, the same below) on the upper plane of the workpiece;
③ Quickly move the spindle so that the end face of the tool is close to the upper surface of the z-axis setter;
④ Use fine-tuning operation to make the end face of the tool contact the upper surface of the z-axis setter slowly until the pointer indicates zero;
⑤ Write down the Z value in the machine coordinate system, such as -250.800;
⑥ If the height of the z-axis setter is 50 mm, the Z coordinate value of the workpiece coordinate system origin w in the mechanical coordinate system is -250.800-50 - (30-20) = -310.800.
(3) Input the measured x, y and Z values into the storage address of the workpiece coordinate system of the machine tool (G54-G59 code is generally used to store the tool setting parameters).

Pay attention to the following problems during tool setting operation:
(1) According to the machining requirements, the correct tool setting tool is used to control the tool setting error;
(2) In the process of tool setting, the precision of tool setting can be improved by changing the fine-tuning feed;
(3) The knife should be operated carefully, especially the moving direction to avoid collision;
(4) Tool setting data must be stored in the storage address corresponding to the program to prevent serious consequences due to call errors.
