Abstract

The invention relates to a turning force measuring technology in turning machining, in particular to an integrated turning force measuring tool system with embedded film sensors. The problems that anexisting turning force measuring technology is low in measuring precision and limited in application range are solved. The integrated turning force measuring tool system with the embedded film sensorscomprises a turning tool bar, a turning tool blade, a first sunk screw, square elastic substrates, the film sensors, a Wheatstone electrical bridge module, second sunk screws, a signal processing unit and a PC; the middles of the four side faces of the turning tool bar are each provided with a square positioning groove; a runway-shaped groove is formed in the center of the groove bottom of each square positioning groove; the four square elastic substrates are embedded into the four square positioning grooves respectively; and the four film sensors are arranged at the centers of the outer sidefaces of the four square elastic substrates in a magneto-sputtering deposition mode. The integrated turning force measuring tool system with the embedded film sensors is suitable for turning machining in various occasions (such as a laboratory and a production field).

Description

technical field [0001] The invention relates to a turning force measuring technology in turning processing, in particular to an integrated turning force measuring tool system embedded with a film sensor. Background technique [0002] In the turning process, the turning force directly affects the deformation of the process system, tool wear, power consumption and cutting heat generation. Therefore, the measurement of turning force is very important for studying turning mechanism and guiding actual turning process. Under the existing technical conditions, the measurement of turning force is mainly realized by strain gauge or piezoelectric force gauge. However, these two kinds of dynamometers have the following problems due to their own structure limitations: First, the problems of the strain gauge dynamometers are: due to the limitation of the bonding process of the resistance strain gauges, on the one hand, it leads to low measurement accuracy; On the one hand, it is not su...
