Abstract A wide variety of cutting fluids are commercially available in the cutting fluid suppliers in order to provide machining performances for a number of industries. In machining, mineral, synthetic and semi-synthetic cutting fluids are widely used but, recently, uses of vegetable based cutting fluids have been increased. Although, these cutting fluids are beneficial in the industries, the...

Ductile cutting are most widely used in fabricating high-quality optical glass components to achieve crack-free surfaces. For ultra-precision machining of brittle glass materials, critical undeformed chip thickness (CUCT) commonly plays a pivotal role in determining the transition point from ductile cutting to brittle cutting. In this research, cutting characteristics in nanometric cutting of B...

The mechanism of cutting process of roadheader with cutting head was researched, and the influences of properties of coal and rock on cutting load were deeply analyzed. Aimed at the defects of traditional calculation method of cutting load on fully expressing the complex cutting process of cutting head, the method of finite element simulation was proposed to simulate the dynamic cutting process...

The dynamics of the cutting process are investigated. Using the increase of cutting depth as a control parameter, two diierent cutting regimes are observed. In the rst regime, which is observed at small cutting depths, complex, high-dimensional dynamics occur. In the second cutting regime, observed for deeper cuts, low dimensional dynamics are typical. The second cutting regime is usually ident...

Real-time Registration of Paper Watermarks The aim of this article is to outline the issues involved in the application of machine vision to the automatic extraction and registration of watermarks from continuous web paper. The correct identification and localisation of watermarks are key issues in paper manufacturing. As well as requiring the position of the watermark for defect detection and ...

There are different uses of soft body in computer graphics and digital entertainment. They are involved in many effects such as fracturing, tearing, cutting. Those objects can have a rest position (in case of blobby effect, cloth) or without rest position (in case of plasticy). The main difference between rigid and soft bodies is the fact soft bodies can change their shapes during the simulatio...

Spinally transected rats given leg shock whenever one hindlimb is extended learn to maintain the leg in a flexed position, which minimizes net shock exposure. Yoked rats, that receive an equal amount of shock independent of leg position (noncontingent shock), do not exhibit an increase in flexion duration. Yoked rats also fail to learn when response contingent shock is applied to the previously...

The aim of this paper is to outline the issues involved in the application of machine vision to the automatic extraction of watermarks from paper samples. The correct identi cation and localisation of watermarks is a key issue in paper manufacturing. As well as requiring the position of the watermark for defect detection and classi cation, it is necessary to insure its position on the paper pri...

The appropriate role of medical professionals in a hospital’s top management team is a controversial issue. Clearly, the medical director plays an important part in balancing medical and financial performance. It is perceived wisdom among medics that the medical director’s position should be strong and on an equal footing with the commercial director. Clinicians believe that relegating their re...

In this paper, a method integrating NC decoding and solid milling simulation to solve this problem is proposed. A modified Z-Map computational algorithm is adopted and it directly uses straight line and arc interpolation algorithms to calculate mesh position and Z coordinates of tool scanning surface according to tool path and initial tool scanning boundary in reducing the long computation time...
