Abstract

The invention relates to the technology of cutting force measurement, in particular to an on-line measurement cutter system of the cutting force of an embedded thin film strain gage transducer. The problems that an existing force measurement instrument is large in size, low in measurement precision and sensitivity, complex in structure and high in manufacturing cost are solved. The on-line measurement cutter system of the cutting force of the embedded thin film strain gage transducer comprises a signal collecting part and a signal processing part. The signal collecting part comprises a cutter rod, a blade, a positioning screw, a pressing plate, a fastening bolt, the thin film strain gage transducer, a wiring terminal, a fastening screw and a connecting line. The signal processing part comprises a voltage feedback operational amplifier, an instrumentation amplifier and a PC. The blade is mounted on the left side face of the front portion of the cutter rod in a fastening mode through the positioning screw, and the thin film strain gage transducer is fixedly mounted in the middle of the side face of the cutter rod. The on-line measurement cutter system of the cutting force of the embedded thin film strain gage transducer is suitable for measuring the cutting force in the metal cutting machining process.

Description

technical field [0001] The invention relates to cutting force measurement technology, in particular to an online cutting force measurement tool system embedded with film strain gauge sensors. Background technique [0002] Cutting force is one of the main physical phenomena in the metal cutting process. Its magnitude not only directly affects the surface quality of cutting thermal processing, tool wear and tool durability, but also is an important basis for the design and use of machine tools, tools and fixtures. Therefore, in the actual cutting process, the measurement of cutting force is of great significance. Under the existing technical conditions, the measurement of cutting force is generally realized by a dynamometer. However, the existing dynamometer is mostly composed of various discrete components, which leads to the following problems: First, the large volume makes it unable to meet the measurement requirements of miniaturization. Second, the measurement accuracy ...
