METALPET

Parts typical of this sector

Small and medium parts, many with precisely located holes and faces in several directions. Relative position matters more than absolute size - which is why a single setup is worth more here than a heavier feed.

Criteria that govern the quotation

Position tolerance between features degrades at every repositioning of the part. Two faces machined in two set-ups inherit the set-up error, however precisely each is machined on its own. Parts with a bolt circle and angled faces are therefore finished in a single set-up on the simultaneous 5-axis centre: the dimensions between features remain the machine’s, not the operator’s. Dimensions taken between features are marked as such on the drawing, distinct from those referred to an edge.
