In actual application, to complete a complete workpiece, several or even 10 to 20 tools may be used in the process. The original method is to try one by one. This method is relatively old-fashioned and the accuracy of tool setting is relatively poor. In reality, it is still rarely used. Today I mainly learn to share with you the following two methods of tool setting.
1. Active tool setting method
Active tool setting is accomplished using the tool inspection function of the CNC machining base equipment. This device can actively and accurately measure the length of each tool in each coordinate direction, and can actively correct the tool error value. All inspection and batch improvement processes can be performed on the machine tool. Completed on the basis of normal operation. This tool setting method is completely completed by electronic control equipment, which eliminates the error of man-made tool setting, so the tool setting accuracy is higher and the tool setting power is also very good.
2. Tool setting method
The tool setting tool is used for tool setting. Because of its higher economical type, it is the primary method for tool setting in CNC machining bases today. The tool setting is divided into two types: internal tool setting instrument tool setting and external tool setting tool tool setting. The tool setting tool outside the machine needs to be calibrated outside the machine tool in advance, and then the tool can be used after being installed on the machine tool; the tool setting tool inside the machine is the method of directly installing the tool in a fixed orientation of the machine tool for measurement .
