Apa sing kudu ditindakake kanggo analisis proses bagean mesin presisi CNC
2023-05-31
The widespread application of CNC precision machining technology in China's manufacturing industry has attracted increasing attention from precision machining practitioners. However, due to the complexity of CNC machining technology, operators need to learn in advance. Especially for the analysis of the machining process of CNC parts, which involves a wide range of aspects, this article will analyze the possibility and convenience of CNC precision machining from two aspects. 1, Penyediaan data dimensi ing gambar bagean kudu tundhuk karo prinsip pemrograman sing trep. 1. Cara dimensi ing gambar bagean kudu adaptasi karo karakteristik mesin CNC. Ing drawing part mesin CNC, pathokan padha bisa digunakake kanggo annotate dimensi utawa langsung nyedhiyani dimensi koordinat. Cara dimensi iki mbiyantu banget kanggo nyenengake pemrograman lan uga mbantu koordinasi dimensi. Utamane kanggo njaga konsistensi ing antarane standar desain, standar proses, standar tes, lan setelan asal pemrograman, ndadekake kepenak banget. Amarga kasunyatan manawa perancang bagean biasane nganggep perakitan lan karakteristik panggunaan liyane sajrone proses dimensi, kudu nggunakake metode anotasi sing kasebar lokal, sing ndadekake akeh kesulitan kanggo proses pengaturan lan mesin CNC. Amarga presisi dhuwur saka mesin CNC lan posisi bola-bali, karakteristik panggunaan ora bakal rusak amarga kesalahan akumulasi gedhe. Mulane, metode anotasi kasebar lokal bisa diganti dadi metode anotasi kanthi pathokan sing padha utawa langsung nyedhiyakake dimensi koordinat. 2. Kondisi kanggo mbentuk unsur geometris kontur bagean kudu cukup nalika program manual, lan perlu kanggo ngetung koordinat titik basa utawa simpul. Nalika pemrograman otomatis, perlu kanggo nemtokake unsur geometris sing nggawe kontur bagean kasebut. Mulane, nalika nganalisa gambar bagean, iku perlu kanggo njelasno apa thkahanan sing diwenehake dening unsur geometris cukup. Contone, busur lan busur tangent ing gambar, nanging miturut dimensi diwenehi ing drawing, nalika ngitung kondisi tangent, padha dadi intersecting utawa loro. Amarga kahanan unsur geometris ora cukup sing nggawe bagean kasebut, program ora bisa diterusake, lan kahanan iki mbutuhake konsultasi karo desainer bagean. 2, Keahlian struktural saben bagean pangolahan bagean kudu tundhuk karo karakteristik mesin CNC. 1. It is best to use a unified geometric type and size for the internal cavity and appearance of the part. This can reduce tool specifications and tool changes, making programming convenient and improving production efficiency. 2. Ukuran fillet alur utama nemtokake ukuran diameter alat, mulane radius fillet alur jero ora kudu cilik banget. Kerajinan bagean ana gandhengane karo dhuwur kontur sing diproses lan ukuran radius busur transisi. 3. Nalika panggilingan bidang ngisor bagean, radius fillet ngisor alur ngirim ora gedhe banget. 4. Iku paling apik kanggo nggunakake posisi standar ndadekake. Ing mesin CNC, yen ora ana posisi pathokan sing manunggal, reinstallation saka workpiece bisa mimpin kanggo disharmony posisi kontur lan dimensi ing loro lumahing machined.
