ABRASIVE SUSPENSION JET TECHNOLOGY AND EXPERIMENTAL STUDY ON CUTTING PERFORMANCE

Cemented carbide rods, which are mostly made by powder extrusion molding, are workblank for various cutting tools. In this paper, new cemented carbide rods, namely GU20, were made by new optimized process, and were manufactured into uncoated and coated cutting tools to evaluate their cutting performance. Experiment results showed that the uncoated and coated tools made of the new cemented carbide rods had better cutting performance than those made of the old rods made by old process.

Edge Chipping

This paper investigates experimentally the edge chipping of a rock to assess the cutting performance of a conical and a pyramidal tip. It was found that the conical tip generates many radiated cracks and results in a larger amount of fine rock grains due to crashing. The size of chips produced by the pyramidal tip is bigger. It was concluded that the critical chipping energy has approximately a linear relation with h9/4 of which h is the depth of cut of the tip.

Grinding Speed

The process of micro-grinding on hard brittle glass is shown in this paper, micro-grinding equipments are designed by tools of electroplated diamond, fz(feed rate), ap (grinding depth), vg(Grinding speed) in micro-grinding brittle materials and their effects to surface quality have been discussed. It has been demonstrated that low surface roughness could be achieved by high vg and low fz. The roughness of Soda-lime glass accomplished by fz:100μm/s, ap:30μm, vg:120000rpm in the experiment is about 78nm.

The Relationship

Waterjet abrasive nozzle is the key component for accelerating abrasive particle velocity and its diameter has important influence on water jet. The relationship between nozzle diameter and waterjet cutting performance has been studied by experiment. The results show: The incision depth and width of specimen decrease linearly with the decreasing of nozzle diameter; The linearity of jet moving direction and the size of kerf angle of specimen are independent of nozzle diameter. Under the same pressure, reducing the nozzle diameter make the penetration capability to reduce, thus, the cutting quality decrease.
