Intermediate · 1 credit · TMT - Trades, Manufacturing and Transportation

Description
Students develop basic turning skills to size, shape and finish common machineable metals and plastics.
Prerequisite
FAB1130: Principles of Machining
Parameters
Access to a fabrication work centre, complete with a metal lathe and accessories, and to instruction from an individual with specialized training in machining practices.
