CHATTER AVOIDANCE AND MACHINING DYNAMICS

 

Chatter vibrations are encountered in all types of component machining - whether it is high speed aluminum machining or low speed steel, titanium machining. If not eliminated, chatter not only degrades part quality and tool life but also lowers productivity and increases cost per component. Chatter cannot be easily suppressed by trial-and-error type testing unless cutting parameters such as axial and radial depths are reduced at the cost of production slowdown.

 

This course focuses on the practice, more than the theory, of establishing a systematic approach to chatter avoidance prior to or encountered during actual machining. Participants will walk through the process of analyzing a problematic cutting process; identifying the root cause; and taking necessary corrective actions to reduce or completely eliminate chatter vibrations. The following topics will be covered during this course

 

• Basics of chatter vibrations in machining

• Introduction to industry standard tap-testing

• Identification and troubleshooting of chatter in machining

• Tips and tricks in determining ideal cutting conditions for CAM

 

COURSE AIMS

 

By the end of this course, participants will be able to

• Identify chatter in machining and most likely the root cause, e.g. tool/tool holder vs spindle

• Systematically find ideal cutting conditions to eliminate existing chatter in production

• Evaluate and compare chatter resistance of different tool/tool holder/machine sets

• Determine optimum cutting parameters for a tool/tool holder/machine sets
