MECHANICAL WORKSHOP

Lab-in-charge: Dr. Sudip Banerjee

Course Objective:

The objective of this lab is to get a hands-on knowledge of several workshops like carpentry shop, fitting shop, sheet metal shop, machining shop, welding shop, etc. and learn safety regulations to be maintained in a shop floor. This laboratory is scheduled for 1st and 2nd semester for all engineering students. Apart from curriculum, some additional experimental setups are there which helps the students to enhance their knowledge. Students also get opportunity to implement their ideas through various application oriented micro projects.

Course Outcome:

Upon completion of this laboratory course, students will be able to

• Fabricate components with their own hands.
• Get practical knowledge of the dimensional accuracies and tolerances applicable for different manufacturing processes.
• Produce small devices of their interest for project or research purpose.

Safety rules & unsafe practices:

Remember that “accidents do not occur; they are caused”. With this in mind, strictly follow the general safety rules given below and safe practices indicated in brief under each section.

• Safety first, work next
• Know your job and follow the instructions strictly
• Avoid wearing loose clothing that might catch, moving or rotating parts. (Long sleeves of shirts, long hair, neck tie and jewellery are definite hazards in the shop).
• Wear safety shoes.
• Keep the area around machine or work clean.
• Keep away from revolving work. Be sure that all guards are in place
• Only one person should operate the machine controls.
• Use tools correctly and do not use them if they are not in proper working condition.
• Wear safety goggles when working in areas, where sparks or chips of metal are flying.
• Know the first aid arrangements for your workplace and have first aid treatment for every injury however trivial.
