CNC lathes usually perform a variety of cutting operations. The difference between the tool position of the previous tool and the position of the newly changed tool at the time of tool change will be different. There are also errors in tool installation, tool wear, and arc radius of the tool tip. If you do not use the tool compensation function to compensate, you will not be able to cut the part that meets the required shape of the pattern. In addition, the rational use of tool compensation...

Introduction: CNC (Numerical Control Machine) is the abbreviation of Computer Numerical Control (CNC). It is an automatic machine controlled by a program. The control system can logically process a program having a control code or other symbolic instructions, and decode it by a computer, so that the machine tool performs a prescribed action, and the rough material is processed into a semifinished product part by tool cutting. CNC (Numerical Control Machine) is the abbreviation of Computer...
First, the tool compensation proposed: Using an end mill to machine a workpiece on a CNC machine tool, it can be clearly seen that the tool center movement gauge does not coincide with the contour of the workpiece. This is because the workpiece contour is formed by the movement envelope of the end mill. The center of the end mill is called the cutter location (4, 5 coordinate CNC machine tool is called cutter location vector), and the movement track of the cutter location represents the tool's...
The Chinese machine tool industry has achieved sustained and rapid development. Until the first half of 2011, the demand is still very strong.
