Investigation of the cusp height when ball-end milling form shaped surfaces

An Instantaneous Rigid Force Model For 3-Axis Ball-End Milling Of Sculptured Surfaces

An instantaneous rigid force model for prediction of cutting forces in ball-end milling of  sculptured surfaces is presented in this paper. A commercially available geometric engine is used to represent the cutting edge, cutter and updated part geometries. The cutter used in this work is an insert type ball-end mill. Intersecting an inclined plane with the cutter ball nose generates the cutting...

Feedrate optimization for ball-end milling of sculptured surfaces using fuzzy logic controller

Optimization of cutting parameters important in precision machining in regards to efficiency and surface integrity of the machined part. Usually productivity and precision in machining is limited by the forces emanating from the cutting process. Due to the inherent varying nature of the workpiece in terms of geometry and material composition, the peak cutting forces vary from point to point dur...

Study of the effective cutter radius for end milling of free-form surfaces using a torus milling cutter

Investigation the Milling Strategies Effects on Machining of Convex Surfaces made of Glass/Epoxy Composite

In this study the effects of machining parameters such as shearing speed, feed rate, tool diameter and machining depth on different milling strategies i.e. 3D offset, spiral, raster and radial to produce the convex surface made of epoxy/glass composites is investigated. The effects of mentioned strategies on output parameters such as surface roughness and milling removal rate is also studied. T...

Analysis of Chatter in Ball End Milling by Wavelet Transform

The chatter is one of the major limitations of the productivity in the ball end milling process. It affects the surface roughness, the dimensional accuracy and the tool life. The aim of this research is to propose the new system to detect the chatter during the ball end milling process by using the wavelet transform. The proposed method is implemented on the 5-axis CNC machining center and the ...
