The modeling of dynamic material removal rate (MRR) control and the optimum solution with tool life determination through Calculus of Variations to minimize the machining cost of an individual cutting tool under expected machining quantity are introduced in this paper. To analyse the cutting forces under the MRR optimization, the mathematical model is formulated by reverse experiments on an E(subscript COCA) PC-3807 CNC lathe, and the electronic circuit is developed through linear regression technique for virtual machining. The inaccuracy between actual voltage and simulated voltage is assured to be within 2%. By introducing the real-world CNC (computerized numerical control) machining case from Air(subscript TAC) into the virtual system, the simulated cutting forces are shown to promise the feasible applicability of the optimum MRR control. Additionally, the implementation of the dynamic solution is experimentally performed on our proposed digital PC-based lathe system. The surface roughness of all machined work-pieces is found to not only stabilize as the tool consumed, but also accomplish the recognized standard for finish turning. This study not only provides the economical solution of virtual machining prior to realization for the optimum MRR, but also advances the realistic implementation through digital PC-based lathe system to the CNC machining industry with profound insight.
