What is the best model to explain metal cutting?

AI Thread Summary
The discussion centers on the challenges of finding a comprehensive model for metal cutting that accurately explains experimental results across various materials and geometries. The Merchant model from 1941 is noted for its lack of realism and failure to align with experimental data, leading to numerous attempts at modification without a definitive solution. Victor Astkhov's critiques of existing models highlight ongoing confusion in the field. The participant seeks guidance on the current state of metal cutting theory, emphasizing the need for accessible resources. The conversation concludes with a suggestion to explore the book "Metal Cutting Principles" by Shaw for a deeper understanding.

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.
 
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
