Subject Description

On completion, students should understand: the basic cutting action, performance, capabilities and latest development in abrasive processes; the development and computerisation of fundamental mechanics of cutting models for the major machining operations such as milling for tool design and performance prediction; the fundamentals of tool wear, tool-life and computer based optimisation of single and multi-pass machining operations for use in process planning.

Topics covered include: abrasive processes: grinding, honing, lapping and super finishing. Bulk material removal processes: mechanics of cutting; analyses of single point and multi point tool processes; machining with form tools, turning, drilling, milling and rotary tool operations. Wear theories and tool-life. Machinability of materials. Computer-aided prediction of machining performance. Economics of material removal processes: objective functions and constrained optimisation of process variables for single and multi-pass machining operations such as turning, drilling and milling. Computer-aided optimisation for off-line process planning and canned cycles for CNC machine tool controllers.

Assessment

One examination not exceeding three hours at the end of semester, tutorial problem sheets, laboratory reports and assignments of up to 15 pages each. Students will be notified of the weighting of assessment components at the beginning of semester.
