Study on Reducing Machining Time in CNC Turning Centre

Machining optimization has an inevitable role in contemporary operation of CNC and non-conventional machining processes. The operating parameters in this context are cutting speed, feed rate, depth of cut etc. that do not violate any of the constraints that may apply on the process and satisfy the objective function such as minimizing the total production time or production cost or maximizing the production rate or combination of several objective functions. Turning is one of the important operations in industries. Hence it is desired to optimize the operating parameters of the turning process. In this work a turned component is considered with turning, facing and undercutting operations. The objective function is to minimize the machining time with constraints such as cutting power, cutting force, tool life, surface finish of the product. For solving the above problem optimization procedure was developed using Genetic Algorithm. The optimization problem was solved and the result was compared with the current practice used in industries.
