Monitoring parts on the machine?

Many machine tools are equipped with probing devices that calculate the positions of various components and establish a work-coordinate system. Although there is a perception that using these probing features will increase cycle times, they actually can boost productivity. The article points out that the probing systems are a form of “on-machine verification” rather than inspection. The difference is that inspection is an independent measurement, while verification is a less precise, but simpler check. Verification does not require the removal of machine tool components for inspection. It is a major time saver to leave all components in place, and additional mistakes are avoided in trying to get pieces back together again. By using probes combined with inspection software manufacturers can monitor, correct, and document in-process operations. When the process is finished, the software can generate a report that shows how accurately the part was manufactured and areas of concern. The verification process can monitor component accuracy at all stages of the manufacturing process. All of this data can be combined and used to create a more accurate and efficient machining process.   Read the full article at Machine Design.
