'''Pengolahan logam (metal working)''' adalah proses mengolah logam unuk membuat perkakas atau suku cadang mesin. Istilah metal working mencakup semua pekerjaan logam yang luas, mulai dari pembuatan kapal-kapal besar dengan koponen baja yang besar dan keras, pembuatan kilang minyak lepas pantai atau pengeboran sampai pembuatan instrumen mesin yang presisi dan pembuatan perhiasan yang kecil dan halus.
Maka dalam bidang metal working mencakup banyak keahlian, keterampilan dan penggunaan berbagai macam peralatan. {| class="wikitable" border="1"
