Integrating MTConnect and NI Measurement Studio to monitor machining process parameters to aid in chatter identification

In any manufacturing environment, it is important to be able to monitor the machining process so that high quality parts can be produced in the shortest amount of time possible to be profitable. Occasionally, situations in the machining operation will arise that will be detrimental to the quality of the part being machined. The MTConnect standard can be used to communicate machining process information regarding chatter conditions to the machine operator and to other users to take action for chatter suppression and avoidance. Chatter is an undesirable phenomenon that can reduce part quality and increase tool wear. These consequences result in higher costs to replace damaged parts and tools as well as increasing the amount of machine downtime which can reduce the company’s overall productivity. Once chatter can be detected audibly, damage to the workpiece may already have occurred. Therefore, an early identification and communication method with the machine tool is warranted to easily monitor the machine in the event of dynamic part damage. This application was developed to provide a means to monitor cutting conditions to reduce and prevent chatter in the machining process and to aid in analysis to avoid subsequent unstable operating conditions.
