Touch Probes for Machine Tools

A touch probe system enables machine tools to perform geometrical measurements inside its cutting area. The probe, a high precision switch, is the heart of the system and when it is integrated into the machine manufacturing process, it can determine workpiece and/or tool sizes and identify part locations. This system can enhance part quality, improve productivity and reduce operators set-up time.

Operating principle

The system utilizes the machine to move the probe along a programmed path. Once the stylus makes contact with the part/tool a signal is generated and is transmitted to the machine's CNC. This is done by means of a transmission system (wireless or hardwired). The CNC is then able to store the relevant axes positions and elaborate the part geometry by means of dedicated probing software.

A typical probing application lay-out is sketched here below:
