Active Suppression of Chatter by Programed Variation of Spindle Speed
Journal of the Japan Society of Precision Engineering, 1975 Among various types of chatters encountered in metal cutting and grinding operations, the regenerative-type self-excited chatter is known to limit the maximum depth of cut possible to be taken in roughing operations. The theoretical analysis of the regenerative-type selfexcited chatter suggests that the spindle speed variation could control the amount ...

A constant cutting speed and feed-per-tooth CAD/CAM algorithm in free-form milling
Engineering Science and Technology, an International JournalBall-end milling is a fundamental process for machining free-form geometries, typically executed via parallel toolpaths over curved surfaces. Due to the continuous variation in tool-surface engagement, the effective tool diameter and cutting speed (m/min)

Suppression of chip load variations by real-time spindle speed modulation [PDF]
The International Journal of Advanced Manufacturing Technology, 2018 In machining a fixed depth of cut at a constant feedrate to generate a desired curvilinear shape, substantial variations in chip load can occur whenever the smallest concave radius of curvature is comparable to the tool radius. These chip load variations may result in a poor quality of the machined surface or premature tool wear. Conversely, attempting

The analysis of tool life and wear mechanisms in spindle speed variation machining [PDF]
The International Journal of Advanced Manufacturing Technology, 2014 Regenerative chatter vibrations generally limit the achievable material removal rate in machining. The diffusion of spindle speed variation (SSV) as a chatter suppression strategy is mainly restricted to academy and research centers. A lack of knowledge concerning the effects of non-stationary machining is still limiting its use in real shop floors ...
