Course detail

Machining of cast materials

FSI-POLAcad. year: 2017/2018

The subject is devoted to the improvement of student’s knowledge in the field of machining of cast materials.

Learning outcomes of the course unit

Students will acquire knowledge of qualified technological process selection, including foundry technology. They will be able to select proper clamping of workpieces, production (cutting) conditions, cutting tools and materials, do workpiece checks, calculate production times and production costs.

Prerequisites

Knowledge obtained in the course of previous study, namely in the fields of theory and technology of machining, material science, metrology, mathematics, physics, structures and properties of cast materials.

Co-requisites
