Since the numerical control systems of imported and domestic CNC machine tools are different, each machine tool needs to be equipped with different programming software, and the respective programming systems cannot be used universally, which makes the repeated investment of programming software and programming machine increase, and needs to be equipped with multiple names. Programmers lack the necessary connections to each other and cannot form an automated production system. In addition, designers mostly use AutoCADR14 or Pro/Engineer software to draw drawings. Because they are not compatible with the programming software used in the workshop, programmers first prepare programs. To enter the design drawings into the computer is equivalent to a secondary design, which requires a lot of repetitive work.
Graphics input often accounts for 40% and 70% of the total programming time. CNC programming is actually repeated drawing most of the time. Due to the above problems, the programming cycle is still too long. When a workpiece with complicated shape and tight processing cycle is encountered, the preparation of the NC program may become the main reason for delaying the construction period.
At present, the design and manufacture of microwave devices are designed first, and then the process is completed. Finally, the serial mode is produced in the following figure. The necessary information feedback between the three links of design, process and production cannot realize resource sharing. Many designs The problems that occur in the process stage are not exposed until the production stage. After the production department finds the problem, it reports to the process and design department and modifies it. Repeatedly, it will take a lot of time and effort to make the production cycle prolong and the product cost increase.
