The purpose of turning and milling compound machining tool setting is to determine the position of the program origin in the machine tool coordinate system. In layman's terms, tool setting is to control the tool nose points of all the tools of the machine tool at the same point. The essence of tool setting is to initially determine a relative position between the tool and the workpiece. According to this position, the next cutting position is determined according to the size to be processed.
1. Trial cutting method
The trial cutting method belongs to the in-machine tool setting method, which is simple to operate and widely used, and is suitable for most situations of lathes.
2. Knife setting
The tool setting block belongs to the manual tool setting in the machine, which is low in cost and fast. Without considering the tool setting accuracy, its tool setting efficiency can be said to be the first.
The tool setting method of the tool setting block is similar to the trial cutting method, except that the spindle does not rotate during the tool setting. allow.
3. Knife setting instrument
Tool setter is an accessory product of CNC machine tools in the rapid development of modern science and technology. It is often used in CNC lathes, CNC milling machines and machining centers. It can be divided into two types: in-machine and several. The tool setting instrument uses the potential of development. Because the number of tools set by the off-machine tool setter is large. High efficiency and wide application. It will have a wide range of application prospects in the future.
The working principle of the CNC machine tool determines that when the machine tool returns to the mechanical reference point of its respective motion axis, the machine tool coordinate system is established. Once the reference point is established, relative to the zero point of the turning-milling machine tool, each movement direction on each axis of the machine tool coordinate system has practical significance in numerical value.
