Keywords: cylindrical grinding, design, chatter vibration, nonlinear friction Nowadays machining in manufacturing industry has become more competitive and de-manding than ever before. Grinding as one of the last stages in the manufacturing pro-cess has been the focus of the research studies in the field of manufacturing for quite some time.

The machining time in the lathe work can be calculated for a particular operation if the speed of the job, feed and length of the job is known. If "s" is the feed of the job per revolution expressed in mm per revolution and "l" the length of the job in mm, then a number of revolutions of the job required for a complete cut will be: l/s.

Conversely if grinding is the bottleneck spending more time machining and exploiting the high finish capability of modern tooling may give best bang for buck. If you wanna make money you have to sweat the details. To sweat the details you need to know what's going on. If you don't know what's actually going on you can't know which details to sweat.
