Course Content / Syllabus

Theory lectures: Introduction to Integrated Mechanical Product Design (Development - Design - Production - Quality Control). The machine shop (structure, operations, facilities, equipment, safety means and hygiene rules). Metrology. Statistical Process Control. Measuring instruments. Control and analysis of measuring systems. Errors and uncertainties. Gauges. Machining materials. Metalworking. Material formation processes (cutting, bending, deep-drawing, forging, drawing, wire- drawing, extrusion, rolling). Material removal processes (turning, milling, drilling, reaming, grinding, planning). Machine tool operation, cutting conditions and correlation with cutting tools. Cutting forces and power of machine tools. Processing times. Characteristics and basic principles of metal cutting (cutting mechanism, chip formation, heat contagion, cutting tools, tool wear, cutting fluids). New technologies for cutting materials (Electrical discharge machining, water cutting, plasma cutting, laser cutting). Rapid prototyping techniques (Stereolithography, Fused Deposition Modeling, Selective Laser Sintering, Laminated Object Manufacturing, 3D Printing - Binder Jetting). Programming of CNC machine tools. Structure and operation of numerical control NC - CNC machine tools.
Laboratory: Use of laboratory measuring instruments to determine the geometry of given objects. Laboratory exercise on sand casting. Laboratory exercise on cold rolling of metal plate. Construction of machining process sheets for cutting a shaft with gradations (cutting conditions calculation). Laboratory training on shaft cutting on a Maximat V13 lathe. Familiarize with cutting tools such as grinder, cutting saw, drills, Bridgeport CNC milling machine. Creation of G-code programs for cutting of a cylindrical object on a CNC lathe and cutting of a prismatic object on a CNC milling machine.
