still detect the signature of a breaking tool. is application often requires the use of multiple sensors, one on each slide. Finally, for small diameter, deep-hole gundrilling opera- tions, monitoring coolant flow can detect incipient tool breakage in time to prevent it. Since the most common cause of tool breakage in these operations is incomplete chip removal, monitoring the coolant flow signature will provide an accurate indication of impending tool failure. Choosing the optimal toolsetting, monitoring and breakage detection technology from the range of options available is a daunting challenge. However, with a better understanding of the relative advantages and benefits of the available choices, it is a challenge you can approach with confidence in the outcome.

Other Non-Contact Technologies ere are three other approaches to tool detection and tool breakage prevention that are worth mentioning. One is the use of acoustic emission sensors to detect breakage in small tools. e second is a similar application of vibration sensors. e third is the use of coolant flow monitoring to prevent breakage. All three are niche technologies that are valuable within their niches. If an acoustic sensor is located in the right place, it can detect the typical 10 to 400 Hz sound that a tool makes as it breaks. is is particularly useful in applications using small tools in the 1-mm to 2-mm range on multiple tool heads with as many as 20 tools working simultaneously. e tools all need to be within almost 20 percent of the same diameter, otherwise multiple sensors will be required. e sensors themselves may be mounted on the machine or on the fixture, depending on the specific application parameters. Vibration sensing is the best solution for a compact machine with many moving parts such as a Swiss automatic. Here, the machine noise masks the sound of the tool breaking, but a one-, two-or three-axis vibration sensor can T h e o p t i m a l t o o l s f o r m e d i c a l p a r t s m a n u f a c t u r e r s The optimal tools for your industry TM F rom small-sized tools to orthopedic implants and appliances to room-sized scanning equipment, medical manufacturers look to Carmex for tools that provide the utmost in precision, finish, and tool life.
