Description

technical field [0001] The invention belongs to the technical field of ultra-precision machining, in particular to a tool setting device for ultra-precision turning. Background technique [0002] In CNC turning machining, the machining origin of the part should be determined first to establish an accurate machining coordinate system, and at the same time, the influence of different tool sizes on machining should be considered, all of which need to be solved by tool setting. The purpose of tool setting is to establish the workpiece coordinate system on the machine tool, which is an essential and very important operation content. [0003] The accuracy and efficiency of tool setting directly affect the processing quality and production efficiency of the product. Therefore, finding a suitable tool setting method, improving the speed and accuracy of tool setting, reducing machining errors and tool setting time is the key to improving production efficiency for turning. , one of t...

Problems solved by technology

Although there is a dual-CCD tool setting device based on image processing, it cannot meet the requirements of ultra-precision turning processing due to factors such as the matching error between the images acquired by the two CCDs, and its system is relatively complicated and the cost is high.
