Analysis of Roughness, Force and Vibration Signals in Ball-end Milling Processes
نویسنده
چکیده
In the present paper, roughness, force and vibration signals from ball-end milling processes are analysed. From the roughness signal actual feed value was obtained as expected. From the force and vibration signals both the frequencies of harmonics corresponding to rotation speed of the tool and impacts of teeth were detected.

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...
متن کاملPrediction of Surface Roughness by Hybrid Artificial Neural Network and Evolutionary Algorithms in End Milling
Machining processes such as end milling are the main steps of production which have major effect on the quality and cost of products. Surface roughness is one of the considerable factors that production managers tend to implement in their decisions. In this study, an artificial neural network is proposed to minimize the surface roughness by tuning the conditions of machining process such as cut...
متن کاملEffects of Helix Angle Variations on Stability of Low Immersion Milling
The stability behavior of low immersion helical end milling processes is investigated in this paper. Low radial immersion milling operations involve interrupted cutting which induces chatter vibration under certain cutting conditions. Time Finite Element Analysis (TFEA) is suggested for an approximate solution for delayed differential equations encountered during interrupted milling. An improve...
