Project: Abrasive Machining Simulations Using Cellular Automata
Abrasive machining is a century-old technology, but it still plays an important role in industry today. The need for high-accuracy and high-efficiency machining of difficult-to-machine materials is making the application of abrasive technology increasingly important. Also, abrasive machining has an advantage that the failure of one cutting edge doesn't affect the process, unlike in other machining processes, because abrasive machining is performed with a large number of cutting edges.
Conventionally, the finite element method (FEM) has been used to model processes and deformation at the macro and micro levels, where the structure is incorporated using averaging constitutive laws.
This project investigates the use of cellular automata (CA) for modeling abrasive machining. A 1D CA will initially be used to model the workpiece as having different heights, to represent the roughness; the force from the abrasives will be modeled to randomly hit the workpiece, thereby smoothing out and polishing the surface. The modeling will then be extended further to two and three dimensions.
Of further interest is modeling nanoscale abrasive machining using the CA to see whether it gives interesting results that could lead to further experimental validations.
