Difference between conventional and non conventional machining

Conventional machining can be defined as a process using mechanical energy while other forms of energy such as thermal, chemical and electrical energy are used by non-conventional machining. Each machining process has different capabilities and suitable for a specific purpose. Now, let us have a deep insight into the difference between those two machining process. 

Difference between conventional and non-conventional machining : 

  • Non-conventional tools are more precise and accurate than conventional tools.
  • Machining is generally done by chip formation while material removal occurs with chip formation or even no chip formation in non-conventional machining. Example - AJM. 
  • Conventional machining process involved tool wearing as there is physical contact between the tool and the workpiece while this is not the case in non-conventional machining. 
  • No noise pollution is created as a result of non-conventional methods as these tools are much quieter.
  • Tool life is long for non-conventional processing as compared to conventional machining. 
  • Non-conventional tools are very expensive than conventional tools.
  • Non-conventional tools have complex setup and hence requires a skilful operation by expert workers, whereas conventional tools do not require any special expert for its operation and are quite simple in the set-up.
  • Easily available replacement parts of conventional machines but not for non-conventional machines.
  • Non-conventional machines can handle very complex jobs as compared to conventional machining.
  • Lower accuracy and surface finish obtained in conventional machining wherein non-conventional machining Higher accuracy and surface finish  are obtained
  • With the use of conventional machining cannot produce prototype parts very efficiently and economically whereby the use of conventional machining produces parts effectively and economically.
  • High waste of material due to high wear in conventional machining whereas no waster of material due to no wear in non-traditional machining. 
  • Conventional machining capital cost is lower as compared with non-conventional machining.
