Optimization the processing of thin-walled polyamide parts

The «Grebenka» is part of the receiving and computing module of the global satellite system devices and is used to position wires in the socket. When developing the manufacturing technology for this part, problems arose due to the properties of the polyamide material and thin-walled structural elements with tolerances for quality grade 9. The design of the part includes grooves and thin jumpers between them. Processing with a disk cutter using conventional milling methods led to the formation of long burrs and increased the likelihood of obtaining defective products due to the difficulties in performing metalwork on small-sized elements while maintaining tolerances for specified dimensions. The solution to the problem resulted in a change in the cutting direction during milling: from downwind to upwind. General cutting recommendations for the part in question are provided. The number of passes during processing was also increased, which made it possible to cut off burrs and eliminate the metalworking operation performed manually, and to meet the requirements of the design documentation in an automated manner. This method is effective in terms of increasing the probability of producing good products, reducing manufacturing time, and can be applied to serial production by automating the production of similar types of parts and structural elements of polyamide
