Exactly! It is an unconventional machining process used to break chips in ductile materials (low carbon steels, for example). It also shows good results in the machining of polymers, pure aluminum and some alloys used in the naval, aeronautical and aerospace industries. Depending on the specific model of the equipment, different types of vibration are obtained (see image).

It seems to me that a similar thing happens on a regular old lathe. The natural vibrations of the tool and work piece create differences in cut depth. Especially in roughing cuts, then when a finish cut is made, the vibrations would be different, resulting in a nicer finish.
The cut off tool is especially prone to vibrations, and failure do to excessive vibration.
Yes hemmjo, there is also a relationship between the depth of machining, the tool nose radius and the rigidity of the equipment. When the cutting edge of the tool is worn or broken, the tendency to cut is vibrating and noisy, which is very irritating. If the machine has excessive play, then the tool makes small bumps and may even break. The secret of the process is to know how to choose and sharpen the tool correctly!
