Intermittent Cutting

Tool-work thermo-electromotive force (E.M.F.) is very important signal because it is regarded as the evidence of direct cutting phenomenon at the cutting position.Our aim is to carry out in-process monitoring of tool wear under intermittent cutting conditions. We examined the relation between E.M.F. and tool flank wear to explore the possibility of in-process tool wear detection using E.M.F. Waveform variations in E.M.F. signals corresponding to tool flank wear were observed at the starting position of cut. To determine the cause of these waveform variations, the electric current was also measured and the electric resistance between the tool and work piece were calculated using Ohm's law. It is found that the change in the tool-work electric resistance corresponds to the progression of the tool flank wear.By monitoring this tool-work electric resistance, it is possible to conduct in-process detection of tool flank wear.

Chip Separation

A coupled thermoelastic-plastic plane-strain finite element model is developed to study orthogonal cutting process with and without flank wear. The cutting process is simulated from the initial to the steady-state of cutting force and cutting temperature, by incrementally advancing the cutting tool forward. Automatic continuous remeshing is employed to achieve chip separation at the tool tip regime. The effect of the degree of the flank wear on the cutting forces and temperature fields is analyzed. With the flank wear increasing, the maximum cutting temperature values on the workpiece and cutting tool increase rapidly and the distribution of temperature changes greatly. The increase of tool flank wear produced slight increase in cutting forces but significant increase in thrust forces.

Wear Tests

Acoustic emission (AE) provides a non-intrusive means of monitoring insert flank wear in face milling. Progressive wear tests of carbide inserts in eight-point milling of annealed En24 steel were instrumented with piezoelectric AE transducers and a non-contact optical interferometer, from which AE frequency information could be extracted. Mean AE frequency was found generally to decrease with wear in agreement with other published studies. Tool indexed measurements enabled the time evolution of the frequency content to be studied on the timescale of a single pass of the insert. The results may be explained by a simple analytical model for AE frequency associated with plastic deformation. The observed AE decay time constants following insert entry decreased with cutting speed, consistent with thermal models of the cutting process. Whereas the results of this study alone would not constitute an independent means of tool wear monitoring, they could provide a diagnosis of tool wear when supplemented with other AE measures and with knowledge of the specific cutting process.
