The cutting tool is moved with sub-micron precision by a combination of electric motors and piezoelectric actuators. Get personalized course recommendations, track subjects and courses with reminders, and more. Sign up for free. Classification of grinding machines and their uses. This course is systemically arranged and taught in smooth as well as clear way so that students understand easily. Articles needing additional references from December All articles needing additional references All articles with unsourced statements Articles with unsourced statements from January Articles with unsourced statements from May For best possible quality natural diamonds are used as single-point cutting elements during the final stages of the machining process.

Tool life improvement has been under consideration in diamond turning as the tool is expensive. Overview Machining is one of the basic and very important courses nptl the mechanical undergraduate students. Introduction to modern machining processes: Cutting Tool Materials of common use. The most often requested materials that are not readily machinable nptep Diamond turned surfaces have a high specular brightness and require no additional polishing or buffing, unlike other conventionally machined surfaces.

  CSA A23.3-94 PDF

Materials that are readily machinable include: Details Material Removal Processes: Basic working principle, configuration, specification and classification of machine tools.

Ferrous materials are not readily machinable because the carbon in the diamond tool chemically reacts with the substrate, leading to tool damage and dulling after short cut lengths. This site also uses cookies to deliver our services.

Diamond turning

KDP is water-soluble, so conventional grinding and polishing techniques are not effective in producing optics. Carter wear, flank wear, nose wear, other tool wears, tool life criteria. Principles of assembly engineering, theory of dimensional chains, fully interchangeable and selective assembly. First Name Last Name. Manufacturing Engineering Mechanical Engineering.

The SPDT manufacturing process produces a relatively maxhinability percentage of defective parts, which must be discarded. Design and Application of typical jigs and fixtures.

Views Read Edit View history. Generation of surfaces by machining, basic operations on shaping, slotting and planning machines, lathe, drilling and boring machines and grinding machines. As a result, the manufacturing costs are high compared to conventional polishing methods. Diamond milling can be used to generate aspheric lens arrays by annulus cutting methods with a spherical diamond tool. This article needs additional citations for verification.

Diamonds also serve in other machining processes, such as milling, grinding, and honing. Production of screw threads by Machining, Rolling and Grinding.

Share your experience with other students. The term single-point diamond turning SPDT is sometimes applied, although as with other lathe work, the “single-point” label is sometimes only nominal radiused tool noses and contoured form tools being options. The form accuracy is measured as a mean deviation from the ideal target form. Sign up for free. Quality control is a major part of the diamond turning process and is required after each stage of machining, sometimes after each pass of the cutting tool.

The machine tool components are placed on top of the granite base and can be moved with high degree of accuracy using a high-pressure air cushion or hydraulic suspension.
