Pangolahan logam (metalworking), minangka jinis teknologi pangolahan lan kegiatan produksi nggawe artikel, bagean lan komponen saka bahan logam.
Bagian logam digunakake ing macem-macem mesin lan peralatan. Bagian logam duwe stabilitas dimensi, kekuatan lan kekerasan, karakteristik resistensi suhu dhuwur lan kurang lan konduktivitas, sing asring digunakake kanggo nggawe bagean sing presisi. Yen dibandhingake karo bagean plastik, ana macem-macem bahan kanggo bagean logam, kayata paduan aluminium, paduan tembaga, paduan seng, baja, paduan titanium, paduan magnesium, lan liya-liyane, kanthi macem-macem sifat. Antarane, ferroalloy, alloy aluminium, alloy tembaga lan alloy seng paling umum digunakake ing produk industri lan sipil. Bahan logam kasebut nduweni sifat fisik lan kimia sing beda-beda, beda struktur lan bentuk teknologi pamroses bagean logam sing beda banget.
Cara pangolahan utama bagean logam yaiku: mesin, stamping, casting presisi, metalurgi bubuk, cetakan injeksi logam.
Mesin minangka proses ngganti dimensi utawa kinerja umume saka workpiece liwat peralatan mekanik. Miturut bedane cara pangolahan, bisa dipérang dadi mesin pemotong lan tekanan. Stamping minangka jinis metode pamrosesan sing nggunakake pers lan mati kanggo meksa eksternal ing sheet, strip, pipa lan profil kanggo ngasilake deformasi plastik utawa pamisahan, supaya bisa entuk bentuk lan ukuran benda sing dibutuhake (bagean stamping).
Casting presisi, metalurgi bubuk lan cetakan injeksi logam kalebu proses kerja panas. Dheweke dibentuk ing rongga cetakan kanthi dadi panas logam cair ing suhu dhuwur kanggo entuk bentuk lan ukuran sing dibutuhake. Uga ana mesin khusus, kayata: mesin laser, EDM, mesin ultrasonik, mesin elektrokimia, mesin balok partikel lan mesin kacepetan dhuwur banget. Turning, milling, forging, casting, grinding, mesin CNC, mesin CNC. Kabeh kalebu mesin.
