Metal Cutting and Machine Tools enables students to demonstrate tool geometry and define tool angles in different systems. Students will be able to differentiate between Oblique and Orthogonal cutting and illustrate the mechanism of chip formation in machining ductile and brittle materials. They will gain knowledge on constructional details and application of various types of machine tools along with their relative advantages and disadvantages. They will be introduced to various gear manufacturing and surface finishing process. They will be able to explain various non-traditional machining process and their applications. They will be aware of fundamentals of CNC part programming. Various principles for designing of cutting tools and Jigs and fixtures will be introduced to the students.

Assessment Tasks and Weightings

To obtain a pass grade in this Subject at least 50% overall must be achieved, and at least 40% achieved in the final examination. Students must also refer to the Subject Assessment Details.

Assessment 1–Lab/Project Concept Report: A team based or individual component report outlining individual or team formation. Team based report outlining formation and member roles, project selection, team and member action plan and a schedule of future activities to achieve the outcome. The report contributes 20% towards the final grade for the subject.

Assessment 2 – Assignments: The assignments are intended to support students achieving the learning outcomes for the Subject and will contribute 20% towards the final grade for the subject.

Assessment 3 – Class Test: The Test contributes 20% towards the final grade for the subject and evaluates progress towards achievement of learning outcomes.

Assessment 4– Final Examination (E): The individual components of final examination enable final evaluation of achievement of learning outcomes and contribute 40% towards the final grade for the subject

It is important that all students familiarise themselves with the University of Technology Assessment Guidelines including those on plagiarism in the Academic Integrity Policy at:
