Four-dimensional dynamic force measurement system for micro-deep hole drilling.

An embedded micro-deep hole drilling force measurement system is proposed and verified experimentally, it is based on resistance strain gauge, weak signal detection method and embedded technology. The system can measure the thrust force, tangential force and two orthogonal components of radial force precisely, continuously and stably in real time, while other similar systems can measure only thrust force usually. The system can replace the complex modelling of drilling process to obtain random changing details of drilling forces, and can also be used effectively in intelligent drilling control research.
