By K.K.SAHOO

Workshop Technology

• Workshop:-A room, area, or small establishment where manual or light industrial work is done.

• Technology:-The application of science, especially to industrial or commercial objectives.

Objective

• To gain the knowledge about the fundamental process of manufacturing and properties of different materials.

• About different tools , equipments, machinery and techniques of manufacturing.

Manufacturing ProcessesOres Metals Castings or Ingots Usable Products1. Primary shaping process( casting, forging, forming,

cutting, rolling, bending, drawing, etc).2. Secondary process:- for desired shape and dimensional

accuracy.A) Machining process:- turning, threading, Knurling, milling,

boring, grinding, etc.B) Joining process:- Welding, soldering, brazing, riveting,

screwing, etc.C) Surface finishing process:- Buffing, polishing, honing,

Anodizing, painting, galvanizing, etc.D) Process effecting change in properties:- Heat treatment,

cold treatment, hot working, etc.
