Control of Chatter by Spindle Speed Variation in High-Speed Milling [PDF]
Advanced Materials Research, 2010 High-speed milling operations are often limited by regenerative vibrations. The aim of this paper is to analyze the effect of spindle speed variation on machine tool chatter in high-speed milling. The stability analysis of triangular and sinusoidal shape variations is made numerically with the semi-discretization method.

Chatter Vibration Surveillance by the Optimal‐linear Control of Spindle Speed and Randomly Varying Spindle Speed [PDF]
PAMM, 2009 AbstractTool‐workpiece relative vibration plays principal role during the process of milling with slender ball end mills. Due to certain conditions, a loss of stability and generation of self‐excited chatter vibration will appear. The paper is devoted to a new approach towards vibration surveillance of rotating tools in modern milling machines. Dynamic

Importance of spindle speed in ring frame
International Journal of Engineering & Technology, 2021 In textile industries, spinning sector plays a vital role because this sector produces the main raw material for the textile industries which is known as yarn. So for getting good qualities garments, it is needed to ensure the good qualities yarn. There are many things which are re-sponsible for producing good qualities yarn.
