Machinist – Module 3

Description

Introduction

A blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light-sensitive sheets. Introduced by Sir John Herschel in 1842, the process allowed rapid and accurate production of an unlimited number of copies. It was widely used for over a century for the reproduction of specification drawings used in construction and industry. The blueprint process was characterized by white lines on a blue background, a negative of the original. The process was not able to reproduce color or shades of grey.

What Will I Learn?

  • Recognise elements located within the title block of a detail drawing.
  • Describe why more than one orthographic projection is needed to show an object on a blueprint.
  • Recognise features, markings, and machine parts from an assembly drawing.
  • Recognise an object from an orthographic drawing.
  • List two basic methods of permanent joining.
  • Illustrate gears, bearings, and belt drives on drawings.
  • Recognise types of screw threads from a specification.
  • Explain what a machine is, and explain what it does.
