Different machines to meet all needs
Jan 25, 2018 · To this aim, a three-dimensional oblique cutting model is developed to simulate the chip formation process of cutting two stacked constituents simultaneously. Different constitutive models and failure criteria are implemented to construct the entire machining behaviors of the stack composite.

Milling is cutting with circular, vertical or oblique to the rotational axis of the tool feed movement. This usually happens with a dentate tool associated with cutting motion. Synchronous Milling. Synchronous milling means that the cutting edge engages in the material with the highest chip thickness and immerges with minimal chip thickness.
