Sentence examples for negative rake from inspiring English sources

The grinding force ratio increases with increasing of the negative rake angle of a diamond grain.

Less tool wear occurred on experiments with negative rake angle tools, larger chip sizes and higher surface velocities.

One has a very simple no-flute unchamfered cutting edge with a large negative rake angle of approximately −45°.

The experimental approach is derived from an orthogonal cutting process, modified to a high speed forming and friction process by using an extremely negative rake angle.

An analytical slip-line field model is utilized to study the cutting mechanics and friction at the tool-chip and tool workpiece interfaces in the presence of the dead metal zone in machining with negative rake curvilinear PCBN tools.

An uncut chip thickness that is smaller than the cutting edge radius results in a large negative rake angle during machining, and built-up edge formation then affects the mechanics of the process.

We imposed two constraints: non-negative rake direction (Lawson and Hanson [1974]) and spatial smoothness of the slip distributions.

This shows that for nanoscale cutting with small cutting depth, as the tool edge radius is quite large compared to the cutting depth, the nanoscale cutting is more similar to the conventional grinding with a large negative tool rake angle.

The results show that greater cutting forces are required in nano-scale polycrystalline machining with the increase of depth of cut, machining speed, and the use of the negative tool rake angles.

A micro-tipped grinding-tool made of boron-doped polycrystalline composite diamond (BD-PCD) and designed with a double-negative back rake angle (DN-BRA) to create compressive stress grinding-milling is proposed and employed.

Firstly, a novel diamond-tool, made with copper-based sintered alloy, is designed and fabricated on-line into a harbor-shaped structure with a hollow shaft and negative back rake-angles.
