1. Understanding of modern manufacturing systems structure – a survey of main subsystems and their mutual interaction; Static and dynamic properties of the manufacturing system, dynamic nature of cutting process, nonlinear phenomena of friction, chatter and other aspects affecting manufacturing system stability; Fundamental knowledge of numerically controlled axes, Computer Numerical Control, control system architecture, human-machine interfacing and manufacturing system condition monitoring; Fundamental approaches to manufacturing systems design theory (Axiomatic design, TRIZ and other alternative approaches).
1. The student should be able to design, i.e., conceptualize, analyze and synthesize manufacturing system in accordance to given functional requirements. 2. The student should develop knowledge, skills and practice for using broad range of CAx modeling methods, including FEM, needed for manufacturing system design and optimization. 3. The student should understand structure of Computer Numerical Control system, its basic architecture and subsystems, and how to specify and/or configure it properly.
Theoretical teaching embraces three basic teaching units: 1. Structure and configuration of the manufacturing system – generic structure of the manufacturing system; morphology, static and dynamic aspects of the machine-tool-workpiece interaction, basics of modal analysis; cutting process dynamics, and stability aspects. 2. Control system – basics of numerically controlled machine tool: servo axis, fundamental principles of servoregulation; interpolation and motion control, architecture and configuration of CNC control systems; 3. Manufacturing systems design – introduction to the theory of axiomatic design, design axioms and corollaries; functional requirements and constraints, design matrix and forms of coupling, complexity - structuring and decomposing designs, domain of technology and processes; Theory of Inventive Problem Solving (TRIZ).
Laboratory exercises are organized within the framework of three exercises: 1. manufacturing system statics, 2. manufacturing system dynamics and modal analysis techniques, and 3. control system NUMA (servo axis, engagement of servo axes and contour control, configuring a manufacturing system). Project: project of an assigned manufacturing system or any of its subsystems, focus being on multidisciplinary (mechatronics) approach in solving the problem posed. Students are oriented to using the Internet, contemporary CAD techniques in the design process, team work and practical verification in the laboratory.
