A research on the radius compensation of the tool tip in CNC turning
CNC machining is widely used in many industries due to its superior performance. In CNC turning, radius compensation of the tool tip is used to fully utilize the machining capacity of the machine tool, reduce the number of manual operations, and improve the machining efficiency. This article will analyze the related issues of radius compensation of the tool tip in CNC machining.
The tool tip radius compensation refers to the tool tip making an arc-shaped movement along the circumference of a circle to take the remaining material off the workpiece. The
radius compensation also makes great use of the cutting tool and increases the stability of the workpiece. Through the use of the radius compensation, the cutting is done more smoothly and efficiently.
There are two basic ways of radius compensation. The first is to pre-program the offset for each tool tip. This is the most common type of radius compensation, as it is relatively simple and can be done without any extra hardware. The other type is a hardware-based radius compensation, where the control of the machine is adjusted to apply the offset automatically. This type of radius compensation is more complex, but can provide improved accuracy and repeatability.
The choice of the radius compensation depends on the specific requirements of the user. Generally, pre-programmed offset is used when the number of passes is not too high, as it is the simplest and most cost-effective method. However, if a higher accuracy is required or the number of passes is increased, then a hardware-based radius compensation should be used.
In addition, when the tool tip radius compensation is used, there are some factors that need to be addressed. Firstly, the selection of the cutting tool should match the requirements of the workpiece. The wrong selection of tool tip may cause excessive cutting force, which may cause damage to the machine or inaccurate machining. Secondly, it is important to select the radius compensation method which meets the machining needs of the workpiece. If the radius compensation method is not suitable, then the accuracy of the machining may be compromised.
In conclusion, radius compensation of the tool tip is an important factor for CNC machining. With proper use of the radius compensation, the machining efficiency and accuracy can be improved. The users should select the appropriate radius compensation method depending on their specific machining requirements, while ensuring that the appropriate cutting tools are being used.
