Auxiliary technology of micro-compound turning and milling machining

In order to ensure the precision of micro-compound turning and milling processing, in addition to using equipment that meets the requirements of precision and stability, carrying out integrity processing, and reasonable planning of processing path planning, it is also important to carry out research on the auxiliary technology of micro-compound turning and milling processing. , Process assisted technology is the key to ensure the implementation of processing technology. Need to focus on the following aspects.

  1. Carry out research on the dynamic characteristics of the machine tool, obtain the various modes of the machine tool, and obtain the optimal cutting parameter range for high-efficiency and high-precision machining, and provide a theory for avoiding machine tool vibration, improving the machining accuracy of parts and reducing machining costs stand by.
  2. Carry out the research on the wear law of micro-tools and tool life evaluation methods, combine the characteristics of the processing technology, the materials of the tool and the workpiece, and the cutting parameters, and give the wear rules of the tools under different process conditions, in order to improve the utilization rate of the tools and realize The compensation of tool wear lays the foundation, which in turn provides technical support for improving the machining accuracy of micro and small parts.
  3. Research on in-situ detection technology of micro-parts. In the process of turning and milling combined processing, realizing the in-situ detection of the dimensional accuracy of micro-small parts, and the in-situ monitoring and detection of the wear or breakage status of micro-small tools are of great significance to ensure the processing quality and processing qualification rate of micro-small parts. Therefore, it is necessary to develop on-site visual control and inspection system hardware and software for micro and small parts to realize online monitoring of the cutting process, in-position measurement of the size of machined parts, in-position monitoring and detection of tool wear and tear, which is conducive to timely error compensation and prevention of malfunctions. The production of qualified parts provides an important means for ensuring the machining accuracy of small parts.
  4. Research on high-precision tool setting methods and tool setting devices. Due to the small size and poor rigidity of micro parts, the non-contact tool setting method is used for tool setting. The current non-contact tool setting instrument on the market has a tool setting accuracy of up to 2μm, which cannot meet the requirements of micro-miniature tool setting accuracy. The precision of parts is required. Therefore, the development of high-precision tool setting methods and devices suitable for micro and small is the key to ensuring the precision of parts turning and milling.
