Simulation of feed cycles for grinding between centres

In order to grind workpieces accurately and efficiently, it is necessary to determine appropriate values of feed rate, target position and dwell time. The selection of optimum values depends on the deflection behaviour of the machine-workpiece system as represented by the system time constant. This paper describes the modelling and the simulation of feed cycles based on a standard simulation package. Simulated grinding cycles are compared with results from experimental measurements. The simulation technique has been employed to reduce the volume of experimentation required to develop and test feed cycles and control strategies. The paper highlights the advantages of simulation in developing a grinding process control strategy.
