Abstract
M.Ing.
The tool geometry in the metal removal process has a substantial impact
on the process performance. This work attempts to vary the geometrical
relationship on-line between tool and work piece. A comprehensive analysis of
the tool's geometry and some machining parameters is presented highlighting
the importance of quantitative knowledge and it's necessity in designing and
operating computer-controlled machining systems. Optimal conditions for
minimum power requirements are established through an analytical simulation
of the machining process. A detailed design of a device facilitating this on-line
geometry variation is described. Experimental results for analysis validation
are included and the reasons for and advantages of tool geometry variation are
discussed.
