Intelligent Tool Wear Estimation for Precision Cutting Tools

Manufacturing Science and Engineering: Volume 2, 1997
Abstract This paper presents a new algorithm for the direct inspection of the cutting tool wear. The place of the direct inspection is discussed. It is shown hat direct inspection does not require to establish experimentally a number of correlations amongst the cutting process parameters for each particular cutting regime, the tool and ...

Reducing tool wear in abrasive cutting

International Journal of Machine Tools and Manufacture, 2005
Abstract The abrasive Cut-Off with stationary or hand-operated machines for cutting or grinding metal is still a very common procedure in many enterprises. Because of the relatively low price of the tool ‘cut-off wheel’ little attention is paid to the life-time of the grits.

WEAR OF ROCK-CUTTING TOOLS

Powder Metallurgy, 1969
AbstractThe conditions under which carbide-tipped rock-cutting tools are employed are very much more severe than any experienced under metal-cutting conditions, vibration of the cutting machine being very significant. Cutting rock also tends to be an intermittent process.Once macroscopic chipping of the cutting edge has been overcome, the predominant ...

Wear Characteristics of Cermet Cutting Tools

CIRP Annals, 1994
Turning tests were carried out with different cermet grades and workpiece materials. Real production processes with permanently changing mechanical and thermal loads were simulated by cut-in/cut-off cycles. The wear behaviour of cermets used in cyclic cutting is not governed by the same laws as in continuous cutting.

Analytical prediction of cutting tool wear

Wear, 1984
Abstract An analytical method is presented which enables the crater and flank wear of tungsten carbide tools to be predicted for a wide variety of tool shapes and cutting conditions in practical turning operations based only on orthogonal cutting data from machining and two wear characteristic constants.

Tool Wear Investigations on Some Cutting Tool Materials

Journal of Lubrication Technology, 1980
Tool life curves were plotted for HSS, cemented tungsten carbides, coated carbides, and cemented titanium carbides. HSS tools showed a distinct inflection coinciding with the formation of a white diffusion layer. Crater wear propagation studies were carried out on all tools and in addition on laminated carbides.

Tool wear monitoring based on cutting power measurement

Wear, 1990
Abstract Methods and devices for in-process tool wear monitoring are focused on turning operations. The implementation of a continuous indirect method based on experimental relationships between wear and cutting power is described, which utilizes a power monitor device for sensing the total power required to drive the spindle motor of the machine ...

The assessment of cutting tool wear

International Journal of Machine Tools and Manufacture, 2004
Abstract Flank wear of cutting tools is often selected as the tool life criterion because it determines the diametric accuracy of machining, its stability and reliability. This paper argues that the existing criteria of flank wear are insufficient for its proper characterization.
