The detailed syllabus for Machine Tools B.Tech 2016-2017 (R16) third year first sem is as follows.
B.Tech. III Year I Sem. L/T/P/C
Course Code:NT502PC 4/1/0/4
Course Overview:
At the very outset of engineering development materials were cut by means of simple hand tools. Gradually, with the development of civilization and engineering, work done by hand tools gives way to the work performed by special machines which are called machine tools.
Hand tools are tools which are held and used by the hands for shaping and sizing a work and there is no mechanism in them. The cutting away of the excess metal in the form of chips or small pieces is simply done by the muscular efforts of man. As a result, the process is time consuming and not gives satisfactory surface finish. It includes files, saw, chisel, scrapper, etc. which are very commonly used in bench and fitting works and assembly of machines.
Course Objectives:
- Machine tools is one of the important subject in mechanical engineering faculty, not only in educational institutional, but it has very much of importance in industrial domain. Without a machine tool, there is no industry.
- A source of power is always needed in various workshop processes particularly in cutting and forming of metal in a machine tool. In the metal-working industry work pieces of most different shapes and dimensions and of different materials are worked. In every industry we need shaping of materials.
- This shaping of materials is done by either non-cutting process or cutting process. For example forging, pressing, drawing, etc are non- cutting shaping processes. Turning, drilling, mailing etc are comes under cutting shaping operations.
- The process of metal cutting in which chip is formed is affected by relative motion between the work piece and the hard edge of a cutting tool held against the work piece. Such relative motion is produced by combination of rotary and translating movements either of work piece or the cutting tool or of both.
- Machining process also include other processes like grinding, slotting, shaping,
honing, planning, lapping, and broaching operations. - After completion of the machine tools course, students can be able to identify various applications of different tools, can be able to differentiate various tools for different machining operations, and also they can be able to solve many industrial problems regarding machine tools. And also as the kinematics of machines studied, students can be able to design various machine tools for various machines.
