TZ 200.02 Engineering drawing: casting

FEATURES:

 

  • Two practice models for technical drawing of cast parts
  • From cast part to finished machine part

DESCRIPTION

Technical Description

A bearing housing made from sand-cast aluminium is used in teaching as an example to illustrate the subject of cast parts in technical drawing in a detailed and practical way. TZ 200.02 comprises two elements: an unmachined cast part, professionally 'polished', as it is delivered from the foundry; and a post-machined cast part additionally presented in the form of a cutaway model. This enables the entire process, from the shaping to the cutting, to be covered in the lesson. Optimal learning is established when one model is used with two/three students.


Learning Objectives / Experiments

Technical drawing:
- drawings of cast parts and their special features: machining allowances, mould drafts, shrinkage, sectional views
- from the cast part to the finished part: production-oriented and standard dimensioning for subsequent machining
Technology:
- manufacture of cast parts by the sand-casting method; manufacturing methods
- machine and tool selection, length measurement exercises
- machine elements and their function
