CNC machining is a technology that uses CNC machine tools to process metal materials under the control of a computer. With its high machining precision and good stability, it is widely used in the machining industry. However, the method to improve the efficiency of CNC machining is a very complex issue. This paper will give some effective methods to improve the efficiency of CNC machining.
1. Optimisation of cutting parameters
Cutting parameters including cutting speed, feed and back draft, etc., is an important factor affecting the efficiency of CNC machining. In the UG cutting strategy to achieve high-speed machining, the following adjustments need to be made: set the step and depth of cut small, rounding the corners, the use of smooth options, set the Nurbs output, the feed, retract, step and non-cutting movement smooth, the use of internal and external tolerances to set the accuracy of the use of internal and external tolerances, the use of helical feed and diagonal feed to reduce the impact of the use of a ball knife to ensure that the amount of cutting is constant, and to ensure that the generation of heat is low.
2. Reasonable selection of tools
Tool selection and installation should consider easy installation and adjustment, good rigidity, high durability and precision. Choosing the right tool can improve machining efficiency and reduce machining time. For example, in high-speed machining of moulds, strategies such as adjusting machining parameters to ensure good quality and optimising the contact point between the tool and the workpiece are required.
3. Optimise programming
Programming is an important part of CNC machining, programming skills include the flexible use of the main program and subroutine, reduce the cumulative error of the CNC system. Optimised programming can reduce machining time and improve machining efficiency. For example, macro program, automatic programming and other technologies can be used to optimise programming.
4. Use of high-speed cutting technology
High-speed cutting technology refers to a technology that carries out cutting processing at high speed. The use of high-speed cutting technology can improve processing efficiency and reduce processing time. For example, in the UG cutting strategy to achieve high-speed machining, the following adjustments need to be made: set the step and depth of cut to a small size, round the corners, use the smooth option, set the Nurbs output, smooth the feed, retract, step and non-cutting movement, use the inner and outer tolerance to set the accuracy, use the spiral feed and diagonal feed to reduce the impact, and use the ball tool to ensure that the amount of cutting is constant, and to ensure that the heat generated is low. Low heat generation.
5. Use of automation
Automation is the use of automated equipment and software for CNC machining. The use of automation improves machining efficiency and reduces manual intervention. For example, automated equipment such as robots and automated production lines can be used to achieve CNC machining.
6. Improve the accuracy and stability of machine tools
The precision and stability of machine tools are important factors that affect the efficiency of CNC machining. Improving the accuracy and stability of machine tools can reduce machining errors and improve machining efficiency. For example, you can carry out regular maintenance and repair of machine tools to improve the accuracy and stability of machine tools.
7. Use of advanced machining technology
Advanced machining technology refers to the use of advanced machining equipment and technology to achieve CNC machining a technology. The use of advanced processing technology can improve processing efficiency and reduce processing time. For example, laser cutting, 3D printing and other advanced processing technologies can be used to achieve CNC machining.
In conclusion, the method of improving CNC machining efficiency is a complex issue that requires comprehensive consideration of cutting parameters, tool selection, programming, high-speed cutting technology, automation technology, machine tool accuracy and stability, and advanced machining technology. By optimising these factors, CNC machining efficiency can be improved, machining time can be reduced and machining quality can be improved.
