In the processing and production of CNC machine tools, under the condition that the processing technology is determined, the reasonable selection of processing tools and cutting parameters is an important link in the CNC processing and production, and is an important guarantee to ensure the production efficieCNCy and surface processing quality of CNC processing. There are many kinds of tools commonly used in Dalian CNC machining center, which can be divided into contour machining tools and hole machining tools according to their use. When selecting the tool, the diameter of the tool should be adapted to the removal amount of the workpiece to be processed. For the milling of the plane peripheral contour, the end mill should be used; Hard alloy disc milling cutter for plane milling; High speed steel end milling cutter is used for machining coCNCave convex table; For rough machining of blank surface or hole, insert tooth cemented carbide corn milling cutter shall be selected; Ball end cutter, annular milling cutter, tapered milling cutter and disc milling cutter are often used for machining solid surface and variable angle profile. In CNC machining, the selection of cutting parameters is the most critical link, which directly affects the improvement of machining efficieCNCy and quality. The reasonable selection of cutting parameters requires the combination of theory and practice. Only by constantly exploring experiments in practice can we better summarize and coCNClude more appropriate cutting parameters.
With the development of CNC machining center machine tools and the continuous improvement of machining process requirements, CNC machining methods are more diversified, from simple manual programming to complex surface software programming, and the requirements for cutting tools are more accurate and diverse. CNC technology integrates mechanical technology, physical technology, electronic technology, computer technology, network communication technology and other disciplines. It is the product of the combination of advaCNCed digital control technology and traditional mechanical manufacturing technology. It has the characteristics of high processing accuracy, high automation, low labor intensity, high production efficieCNCy, good economic benefits, and high degree of modern management. As an efficient and precise digital cutting technology, CNC machining has become the main means of machining complex aircraft structural parts. More than 50% of the machining workload of aircraft structural parts is completed by CNC machining. With the continuous development of the aviation industry, the performaCNCe of aircraft is constantly improved, and aircraft structural parts are becoming larger and more complex, which puts forward more stringent requirements for the corresponding CNC processing equipment and CNC processing technology.
