Cutting Process Optimization in Scenery of High Flexibility

In previous work the authors developed a procedure model for cutting process optimization based on the collections of machining data in real time with the occurrence of the process in factories shop floor. This procedure showed to be appropriate for production in mass or for batches with great number of pieces. In these cases, it was possible to determine the Taylor’s Equation coefficients, and it was not necessary running over the data of catalogs, what would supply less precise results. However, for several batches with small number of pieces each to be machined in the same machine (flexible production), the Taylor’s Equation coefficients determination is not viable under technical and economic point of view. This is because it would be necessary determination of data of the tool life through pilot experiences, what would thwart the own concept of flexible production. In the other hand, the data of tool manufactures catalogs are appropriately used by their costumers. This work proposes a procedure model to be applied for flexible cutting process. It takes in account only one set up for a group of tools to be used to machine several batches, each one with a small number of pieces in a same machine. To calculate the tool life, the model can use data from tool manufacturer’s catalogs or, alternatively, data obtained from experiences with pilot’s batches, whenever it is possible to accomplish them. The results showed that the optimization procedure model can introduce larger productivity and smaller cost, when compared with traditional model that uses set up for each batch to be machined, without caring with the size of them
