Acquisition of theoretical and practical knowledge of design, computations and constructions of clamping fixtures, sheet-metal processing tools, metal pressure casting tools, forming and shaping plastics tools and forging tools, all this based on modern technologies and optimal solution.
On successful completion of the course, students should be able to: • Identify different cutting tools and fixtures to use them in a respective metalworking process by cutting. • Evaluate each element with respect to differences in positioning, clamping and present accompanying errors. • Identify different fixture concepts and perform accuracy computations. Students acquire the skill to understand more clearly the concept of metalworking process accuracy. • Describe in brief the cutting tool and fixture used for manufacturing a specified product.
Theory of the principles of work-piece locating and positioning. Theory of the cutting process, determination of the principle machining factors, deformation force and deformation work. Stability theory. Theory of elastoplastic deformation. Determination of the principle machining factors in plastic deformation processing. Construction and computations for elements of clamping fixtures, computations for clamping fixtures accuracy, sheet-metal processing tools, construction characteristics of tool elements, forging tools, metal pressure casting tools, and forming and shaping plastics tools.
Laboratory exercises where students accomplish practically the task of cutting tools and fixtures conception. Of the cutting tools, students are acquainted with the design of turning tool, drill, counter-bore, reamer, tap, milling cutter, wheel, as well as with engineering materials used to make cutting tools. Of the clamping fixtures, students are familiarized with three-jaw chuck, rotating center, rest, lathe dog, wedge-lock vise, expansion collets, as well as with the design of universal, special and universal jig and fixture system. Design project for a concrete task related to engineering practice.
