Effective method of tool setting in CNC machining
Before the implementation of the CNC processing program, the cutter should be aligned to confirm the position of the starting point, and the cutter is usually a headache for the operator. After the tool grinding, the cutter should be aligned from scratch again. The wear of the tool tip is unique. When many cutters are processed, the cutter compensation value should also be measured.

1. Click on the right blade
According to the key of the control panel, the CNC processing equipment touches the tool tip lightly on the surface of the workpiece (X and Z targets are pointed twice), clears the counter, and then returns to the initial position (X and Z design initial values) to be set, and clears again to get the initial position of the tool. The initial position of each knife is determined sequentially and adjusted to the correct design position (starting point) after trial processing. This method can be operated without any auxiliary tools, but it takes a long time. The unique feature is that the tool must be adjusted from scratch every time it is grinded.
2. Choosing tool-setting instrument
Nowadays, many lathes are equipped with knife alignment instruments. The errors in measuring the removable value of knife alignment by using knife alignment instruments have greatly increased the accuracy of knife alignment. Because using knife alignment instruments, it is advisable to automatically calculate the difference between the length and width of each knife and store it in the system. When processing other parts, only standard knives are needed, such as standard knives. This saves time greatly. The need for attention is that there is usually no standard tool for tool alignment with tool alignment instrument, and the standard tool should be aligned at the time of tool alignment. The disadvantage of this method is that it is expensive and difficult to load and unload knife alignment instrument because of the need to add auxiliary equipment to knife alignment instrument.
3. Choosing CNC Tools
After the initial positioning of the tool for CNC machining, after a period of time, wear occurs and the demand for grinding occurs. The position of the tool tip installed from scratch after ordinary tool grinding has changed. The demand for the tool tip is changed from scratch. The characteristic of the CNC tool is that the repeated positioning accuracy of the tool is controlled at 0.02 mm after the tool is manufactured with high precision and the blade is rotated, which greatly reduces the positioning accuracy. At the same time, the blade is coated with metal (Sic, Tic, etc.) to improve its durability, but the cost is also a little high.
4. Use the tool-setting block to set the knife, and select the automatic tool-setting method.
A simple pair of cutter blocks made of plastics and plexiglass is simple to finish repeated positioning after grinding, but the positioning accuracy is usually poor between 0.2 and 0.5 mm. It is a rapid positioning method, and then it can be adjusted quickly and easily.
