Process integration and automation are becoming increasingly important for improving productivity. When two workpieces are parallelly machined on a single machine, vibration transmission by multiple machining points makes it difficult to select optimal cutting conditions, achieving both accuracy and efficiency. This study presents a method to introduce the optimal condition in simultaneous machining with different processes. The developed simulation includes machine dynamics and simultaneous machining process model. Vibration transmissibility between the processes is calculated and the cutting condition with less roundness is proposed. An experimental result shows the proposed method can determine cutting condition the higher accuracy in short time.
