Abstract
An arrangement for controlling the process of rotary chip removing machining of a work piece includes a monitoring system for monitoring the rotary chip removing machining. The monitoring system has at least one surface acoustic wave sensor and at least one first antenna mounted to a cutting tool. At least one second antenna is arranged for wireless communication with the second antenna. Each sensor detects at least one parameter of a group of parameters consisting of strain, temperature and pressure. The sensor and the first antenna transmit the detected at least one parameter to the second antenna in response to an interrogation signal received by the first antenna. A processing unit is connected to the second antenna and transmits the interrogation signal and transmission energy to the first antenna and to the sensor via the second antenna. A control system communicates with the monitoring system to control the machining of the work piece at least partially based on the detected parameter. A cutting tool is provided with the at least one sensor and the at least one first antenna.
