数控对刀方法(国外英文资料) Car number setting The lathe is divided into a cutter and a cutter, but the principle of the tool is the same. First, there is no cutter The lathe itself has a mechanical origin, you generally want to try cutting knife ah, like a knife after the car outside Z to exit, what is the measurement of the outer diameter of the car, and then find you with a knife, move the cursor to the X input X... By measuring machine tool that the cutter on the tip position. The diameter at the G screen, Z to be simple, put each knife in Z to touch a place and then measuring Z0. In this way, all the knives are recorded, and the machining zeros are determined in the workpiece movement (offshift), and any knife can determine the origin of the workpiece In this way, the tool must remember to read the knife before setting the knife There is a more convenient way is to use the tool we know chuck, chuck diameter, tool diameter can touch input, the diameter can take a block with hand pressure in the chuck on the same input, chuck diameter can be. If there is a cutter, it will be more convenient, and the tool cutter will be equivalent to a fixed tool cutting. The tool will be recorded when it touches it So if it is a small batch of a variety of processing, it is best to buy a tool with a knife. Save time I used the MAZAK lathe, I change a new workpiece, from downtime to new workpiece batch processing, intermediate time is generally only 10 to 15 minutes ========================================= Basic coordinate relation of NC lathe and comparison of several tool setting methods In the process of NC lathe operation and programming, it is very important to make clear the basic coordinate relation and the principle of tool setting two. This helps us to better understand the machining principle of machine tools and modify the dimensional deviation during processing. Basic coordinate relation In general, two coordinate systems are commonly used: one is the mechanical coordinate system
