A hydraulic clamping device was developed for the broaching process of Brackets used in automotive braking systems, which allows reducing the variation of the cutting process by improving the clamping system and thereby limiting the deformation of the piece after having been processed. With this concept of device, it is possible to improve the conditions of the production process such as: cutting speed, cycle time reduction, operation performance, scrap cost reduction, and downtime reduction due to process over-adjustment and change over. Additionally, the development of a part detection system was made that allows capturing when a part is not correctly placed in the device before starting the cutting cycle, with this it is possible to detect failures in the process that represent a risk to the operation. During the design stage, a simulation of the machining process was carried out in extreme conditions and ideal conditions to measure the deformation of the part and with this obtain the appropriate cutting parameters for the implementation of the clamping device. For the validation of the model, a Cpk and Ppk process ability study was carried out (according to customer requirements) to assess that the new process is efficient and is under control.
