A stereoscopic cutting of stereoscopic display of 3D virtual objects in a real space using a human binocular parallax is discussed. For the cutting of stereoscopic image objects characterized by assumed physical properties, a software knife and two kinds of hardware edged-tools are developed by which the objects can be directly cut into without any particular constraint in their operation. Some...

The prediction of cutting forces is critical for the control and optimization machining processes. This paper concerned with developing model in micro-grinding. approach based on probabilistic distribution undeformed chip thickness. a function process kinematics, properties workpiece, micro-topography grinding tool. A Rayleigh probability density used to determine maximum thickness as an indepe...

Water vapor jet assisted metal cutting is a pollution-free green cutting technique. This paper has developed a three-dimensional finite element model of water vapor jet assisted cutting in order to understand the influence of its cooling and lubricating effect on cutting process. The cooling effect of water vapor jet is modeled with a convective heat transfer coefficient. A window with the temp...

A dynamic cutting force and vibration model of the microendmilling process that accounts for the dynamics of the microendmill, influences of the stable built-up-edge, and the effects of minimum chip thickness, elastic recovery, and the elastic-plastic nature in ploughing/rubbing has been developed. Experimental validation has been performed, and the model is shown to predict the cutting force a...

(Adaptive Control Constrains (ACC) as applied to machine tool systems refers to the regulation of the cutting process characteristics such as spindle power, cutting force etc., by varying the only changeable process parameters which are feedrate and cutting speed. Even a simple ACC system, as in this case, in which the cutting force is regulated by changing the feedrate, is quite complex. Exper...

This paper presents the suitable depth of cut, spindle speed and feed rate that will be chosen during machining. If thus parameters are not considered, this can provoke abnormal tool behavior such as chatter. Chatter will limit the tool life which only can be use for just a few times. To predict the chatter occurs, the parameters will be use are spindle speed, depth of cut and feed rate. CNC ma...
