4. Blade and saw cutting

To understand the principles of cutting, we often start with a simple case, known as "static cutting", in which a blade penetrates vertically into a homogeneous product of thickness e. The phenomena that come into play in this case result from the application of a force (F ) on the blade. The phenomena involved result from the application of a force (F ) to the blade. This force is distributed over the various faces of the blade: the cutting edge, the bevelled faces and the side faces (N ₁ , N ₂ , N ₃ , N ₄ , T ₁ , T ₂ , T ₃ , T ₄ ...
