What is the best model to explain metal cutting?

Click For Summary
SUMMARY

The discussion centers on the challenges of understanding metal cutting theory, particularly the inadequacies of historical models such as the one proposed by Merchant in 1941. Despite numerous attempts to refine this model, it remains unrealistic and inconsistent with experimental data. Victor Astkhov's critiques highlight the ongoing confusion and lack of a universally accepted model that accommodates various materials and geometries. The conversation emphasizes the need for a comprehensive overview of current theories and practices in metal cutting.

PREREQUISITES
  • Understanding of metal cutting principles
  • Familiarity with historical models, specifically Merchant's model
  • Knowledge of experimental data analysis in machining
  • Access to resources like "Metal Cutting Principles" by Shaw
NEXT STEPS
  • Research contemporary critiques of metal cutting models, focusing on Victor Astkhov's insights
  • Explore advanced modifications to Merchant's model and their experimental validations
  • Study the latest developments in metal cutting theory through academic journals
  • Investigate interlibrary loan options for accessing "Metal Cutting Principles" by Shaw
USEFUL FOR

This discussion is beneficial for mechanical engineers, machining specialists, and students seeking to deepen their understanding of metal cutting theories and their practical applications.

When I ask for the best I mean the one which explains better the experiments.

My problem is that I tried to learn but I´m a bit confused, I know that metal cutting theory has a large history, and it has had a lot of experimentation but when I try to find the theory it´s like it wouldn´t exist a model which explains every kind of situation (different materials, geometries...)

I mean Merchant proposed in 1941 a model, but it was not realistic and it didn´t agree with experimental data, there have been a lot of attempts to modify this theory in order to eliminate the problem but I don´t know if it has been achieved.

I have read Victor Astkhov´s website and he criticizes a lot of models.

I´m not going to classes so I´m alone at this, I only have internet. Anybody could show a general picture about the "state of the art" in metal cutting theory?.

Thanks!

Thank you for your answer, I´ll try to buy it.
