This paper describes a comparison of the mechanical structures (a double-sided beam and a cantilever beam) of a probe in a tool edge profiler for the measurement of a micro-cutting tool. The tool edge profiler consists of a positioning unit having a pair of one-axis DC servo motor stages and a probe unit having a laser displacement sensor and a probe composed of a stylus and a mechanical beam; on-machine measurement of a tool cutting edge can be conducted with a low contact force through measuring the deformation of the probe by the laser displacement sensor while monitoring the tool position. Meanwhile, the mechanical structure of the probe could affect the performance of measurement of the edge profile of a precision cutting tool. In this paper, the measurement principle of the tool edge profile is firstly introduced; after that, slopes and a top-flat of a cutting tool sample are measured by using a cantilever-type probe and a double-sided beam-type probe, respectively. The measurement performances of the two probes are compared through experiments and theoretical measurement uncertainty analysis.

The experimental investigation of UAT shows that the movement of cutting tool edge relative to the workpiece results from the cutting speed, feed speed and tools vibration in tangential direction affects the lateral machined surface of workpiece and leaves a repeating pattern of toothed regions on it. In UAT process, because of constant feed rate of tool toward workpiece, the cutting tool never separates from workpiece, though the tool rake face may separate periodically from chip in every cycle of vibration. This results in an increase in the surface hardness of the lateral machined surface in comparison with conventional turning (CT). The results of the present study confirm the advantage of UAT as far as the lower cutting force is concerned compared with CT. The higher surface hardness of the lateral surface observed in UAT causes the maximum cutting force to increase but the average force decreases with respect to CT.

Physical Quantities

At low machining speeds, self-excited chatter behavior is dominated by factors which have never been satisfactorily explained. By studying the forces acting on the cutting tool right behind the cutting edge, the authors have developed a physical explanation for low-speed stability. This leads to an understanding, in terms of physical quantities, of how such variables as tool edge roundness, tool clearance angles, and chatter frequency affect stability. The explanation is consistent with all published experimental observations of low-speed chatter behavior.

The Way

In the case of metric thread, a possible source of the flank error could be the position of the cutting tool edge, which could not intersect the circular cylindrical surface axis. An analytical method of approximation was applied to model the way in which the flank error is generated by considering some geometrical conditions. A theoretical simplified model was determined to highlight the influence of the thread external diameter and of the distance between the circular cylindrical surface axis and the thread rectilinear generatrix on the profile error of thread flank.

Edge Preparation

Regrinding of wasted cutting tools can recycle resources and decrease manufacturing costs. Influence of relative tool sharpness and tool cutting edge angle on tool edge radius were analyzed. Cutting force and cutting temperature were simulated with FEM on different edge radius. Edge preparation experiments were carried out though an abrasive nylon brushing method. The results show that RTS and cutting edge angle have influence on edge radius. Small edge radius might result in small cutting forces and lower average temperatures, could maintain the cutting state between tool and workpiece. The cutting edge defects can be eliminated through edge preparation, and a smooth cutting edge can be obtained. Cutting tool life will be improved through proper edge design and edge preparation.

Edge Tool

The hand tools for cutting plastic pipe are very useful. However, these tools require the user to exert enormous amounts of power. In order to improve the cutting performance of hand tools, we investigated the relationships among the geometry of the cutting tool, the distance between the supports of the plastic pipe, and the cutting force. We manufactured a special device for measuring the force required for cutting. Because the cross section of plastic pipe is not uniform, the cutting force does not remain constant and exhibits large peaks at the initial and the final stages of cutting. It is found that the cutting force increases with the increases of the angle of the tool edge or with the increases of radius of the tool tip. In addition, the friction force is a major component of the cutting force during the entire cutting process, and the frictional coefficient is greatly affected by the grinding direction of the tool.
