Ensuring accuracy of contour milling on CNC machines

Mechanics and Advanced Technologies, 2023
Contour milling is characterized by quasi-stationary, which leads to the occurrence of a machining error caused by elastic deflections of the machining system.

Analytical and experimental study of feed rate in high-speed milling [PDF]

, 2013
In the context of high-speed milling (HSM), during the machining process dynamic machine response has to be identified. To achieve this, we have to calculate the feed rate evolution in linear and circular interpolation according to dynamic performance of

Cutting Forces Parametric Model for the Dry High Speed Contour Milling of Aerospace Aluminium Alloys

Procedia Engineering, 2013
AbstractCutting forces is one of the most important outputs in material removal machining processes. Their values depend on a large number of parameters, such as the cutting tool material and geometry, the workpiece material or the cutting parameters, among others.

Feed rate modeling in circular–circular interpolation discontinuity for high-speed milling [PDF]

, 2013
In this paper, a modeling approach is presented in order to evaluate feed rate during a circular interpolation in high-speed milling. The developed model depends on the type of discontinuity and the kinematic performance of the machine tool.

On the stability of high-speed milling with spindle speed variation [PDF]

, 2010
Spindle speed variation is a well-known technique to suppress regenerative machine tool vibrations, but it is usually considered to be effective only for low spindle speeds.
