AUTOMATION MONITORING OF CUTTING FORCES DURING MILLING AND DRILLING

Abstract

Commissioning of products made of new composite materials significantly reduces the weight of the structure, which is an important indicator in the transport construction and manufacture of special equipment used in agriculture. For example, reducing the weight of the car by 1 kg saves up to 100 liters of fuel per year. Nevertheless, there are problems associated with the measuring of cutting forces associated with the absence of experimental values of a number of coefficients used in calculations. (Research purpose) The research purpose is developing a device for measuring cutting forces and an automated control system for measuring, transmission and storage of data. (Materials and methods) The solution to this problem was constructed on the basis of the method of reengineering the existing dynamometer design with the introduction of undocumented capabilities of the dynamometer base to determine the cutting forces at all three coordinates Px, Py, Pz and the torque that occurs during cutting. (Results and discussion) The article presents the polymer material and the additive technology used to manufacture the dynamometer. The method of selection of deformation control sensors was substantiated and a methodology for setting up and calibrating the data collection and control system was described. The article presents an automated control system for measuring cutting forces, processing, transmitting and storing information. (Conclusions) The experimental and industrial studies of dynamometer designs made it possible to develop a cheap device for measuring cutting forces with an automated control system for monitoring, transmission and storage, which makes it possible to optimize production, and save equipment and tool resources.
