Course on Computer Aided Machine Drawing

  • by Bhavya
  • Course level: Intermediate

About Course

This course deals with the national and international standards pertaining to engineering drawing practices such as how to sketch the engineering drawings, apply limits, fits, tolerances to assemblies, choose appropriate fits for given assemblies, interpret the machining and surface finish symbols on the components of the drawings.

Description

As it is said drawing is the language of engineers thus any engineering drawing should be sketched manually or by using computers one should have basic knowledge of engineering drawing where the drawings generated either manually or by computer should show the complete information on the drawing such dimensions, bill of materials, limits, fits, tolerances, machining and surface finish symbol etc. so that drawing are complete in all respect. Thus, all these aspects have been incorporated in the course content which will help engineers for linking functional and visualization aspects in the preparation of the part or assembly drawings as per the conventions. Thus, engineers can acquire the basic knowledge of sketching/drafting the engineering drawing by attending this course.

What Will I Learn?

  • Familiarity with national and international standards pertaining to engineering drawing.
  • Understand and interpret drawings of machine components leading to preparation part or assembly drawings manually and using computer.
  • Know the importance of linking functional and visualization aspects in the preparation of the part or assembly drawings as per the standards.
