To improve the quality of the pieces produced and to lengthen the service life of grinding machines, since several decades are available on market systems for control of workpiece dimensions and mechanical conditions of the machines during working cycle. These are devices for the measurement of pieces, for the measurement and reduction of vibration due to the unbalance of the grinding wheel; for the analysis of signals from acoustic sensors, thermal transducers and for analyzing mechanical deformations. There are specific devices for each of the above functions, each with its own physical characteristics and their interfaces. It 'obvious that different systems involving different installation modes complicating the general plant and the machine logic program. P7 has the main feature of being able to connect and manage all types of sensors and transducers so with simplify the installation and the dialog mode with the PLC or CNC machine. Also the display interface dedicated to the operator of the machine is as homogeneous albeit specific for the different functions.
P7 is a modular device whose dimensions and performance are configured as a function of the necessary controls to the specific machine. There is a master board that coordinates and manages the different cards / functions and presiding over the mode of communication with the logic of the machine and the operator interface. The programming of the different cycles is at the end user care that determines, entering the proper values for the parameters, the characteristics to be monitored before, during and after the machining process. Is possible automatically acquire the dimensions of the diameters or lengths of the pieces, to assess vibrations, analyze noises, temperatures, comparing with thresholds programmed the various values in order to take decisions to the machine and / or to the operator care.
