1. Introduction to workshop technology

INTRODUCTION TO WORKSHOP PRACTICE, SAFETY, CARE ANDPRECAUTION IN WORKSHOP1.1 IntroductionWorkshop practice is a very vast one and it is very difficult for anyone to claim amastery over it. It provides the basic working knowledge of the production andproperties of different materials used in the industry. It also explains the use ofdifferent tools, equipments, machinery and techniques of manufacturing, whichultimately facilitate shaping of these materials into various usable forms. Ingeneral, various mechanical workshops know by long training how to useworkshop tools, machine tools and equipment. Trained and competent personsshould be admitted to this type of mechanical works and permitted to operateequipment.Processes:1. Primary shaping processes2. Machining processes3. Joining processes4. Surface finishing processes5. Processes effecting change in properties

1.1. Primary shaping process

Some of these finish the product to its usable form whereas others do not and it requires further working to finish the component to the desired shape and size.Wire drawing lead to the directly usable articles, which do not need further processing before use.Casting, forging, bending, rolling, drawing, power metal forging,

1.2. Machining process

1.1.2 Machining processes
Large number of components need further processing after primary processes
known as secondary operation to obtain desired shape and dimensional accuracy.
These operations require the use of one or more machine tools, various types of
cutting tools and cutters, job holding devices, marking and measuring instruments,
testing devices and gauges etc.
Common machining operations are:
Turning, Threading. Drilling, Boring, Planning, Shaping, Sawing, Milling,
Grinding, Slotting, etc.
