Introduction
Tool compensation is one of the significant technologies of computer-controlled machining. It is done to adjust the real coordinates of the machined surfaces according to the specified virtual coordinates. The purpose of tool compensation is to adjust the machining tool path taking the correct size of the workpiece and the specific shape of the cutting tool into account. This is done to minimize cutting error, reduce machining time and maximize quality and productivity.
The use of tool compensation in CNC machining
Tool compensation is widely used in CNC machining for various purposes. It is used to reduce the effects of tool wear on the machining results, optimize the sharpening profile, and generate the best machining conditions for the machined part. Tool compensation can also compensate for the difference between the real size of the workpiece and the nominal size, and adjust the cutting tool and workpiece to obtain the desired depths, angles, and geometries. In addition, tool compensation can reduce the machining errors caused by thermal expansion, temperature fluctuations, and vibration of the machine.
The use of tool compensation helps to improve the accuracy of the machining process. This is because tool compensation can be used to accurately calculate the cutting parameters based on the geometry and size of the parts to be machined, which helps to reduce the tool cutting error and improves the overall machining accuracy. The use of tool compensation also helps to reduce the lead time and production cost. This is because the tool position is automatically adjusted, and the cutting depth is automatically changed according to the workpiece size, thus reducing the set-up time and production cost.
Types of tool compensation
Tool compensation is divided into two main types: static tool compensation and dynamic tool compensation. Static tool compensation is used to compensate for the geometric variations between the cutting tool and the machined part. It is used to adjust the tool path according to the shape and size of the tool and the machined part. On the other hand, dynamic tool compensation is used to adjust the cutting parameters according to the real-time changes in the workpiece size and shape. It is used to adjust the cutting parameters according to the cutting forces and temperatures.
Conclusion
In conclusion, tool compensation is an important technology in computer-controlled machining. It is used to reduce machining errors and minimize cutting time to maximize productivity and quality. Tool compensation can be divided into static and dynamic types, depending on the type of adjustment needed. The use of tool compensation helps to improve the accuracy of the machining process, as well as to reduce lead time and production cost.
