Computer Aided Manufacturing - a.y. 2016/2017


CFU: 9

Period (Year/Semester): II/I

Languade: Italian

Required/expected prior knowledge: Nothing.

Lecturers: Antonio Langella  

Course objectives:
The overall aim of this course is to introduce students to advanced mechanical computer aided manufacturing concepts and their applications in the mechanical product lifecycle, with particular focus on the machining operations. On completing this course successfully the student will be able to: successfully develop a process plan and NC code for a part given as a CAD model, use CAM software packages for different types of products and machining operations, and optimize the cutting parameters for high precision and efficient CNC machining.

Tables of contents: 
Introduction to metal cutting: machining operations (single point cutting process, multipoint cutting process, abrasive cutting process); cutting tools (materials, coatings, and tool geometry) and tool wear mechanisms; cutting forces; surface finish modeling; surface generation.Selection of cutting parameters in machining operations: criterion of minimum cost and maximum productivity; optimization of the cutting parameters of a multi pass process.Stages and phases of the manufacturing process planning, machining process and operations analysis, tolerances and precision determination, project of the suitable machine-tools and tools for the manufacturing of parts from point of view technology and economy, process plan alternatives evaluation, time and costs of the production.CNC programming, G-code for CNC machining, overall structure of the CNC machines, CNC machine tool categories, CAM systems, machining simulation, machine tools simulation.

Education method: 
Lectures and exercises. The course will include lectures demonstrating CAM concepts, hands-on projects and in-class exercises employing commercial mechanical CAM systems for CNC machining simulation.

Textbooks and learning aids:
P. Smid, CNC Programming Handbook, Industrial Press Inc., 2nd edition, 2002, ISBN-10: 0831131586.
V. Sergi, Produzione assistita da calcolatore, CUES, 1998, ISBN: 8887030065
Lecture notes 

Assessment will be written and oral. Each student is required to write a final project in which a complete process plan for a part given as a CAD model is developed using a CAM Software.
