The stages of contact between a metal chip of AISI 1018 steel and a coated cutting tool creates significant opportunities for manufacturers of machined products to understand how dry machining and minimum quantity lubrication affects the economics of manufacturing. The present work not only compares various computational approaches to the solution of shear plane and tool face temperatures during dry machining with nanostructured coated milling tools, but also explains why there is a large discrepancy when calculating temperature generated during machining when using Loewen and Shaw’s method for calculating shear plane and tool face temperatures.

Paper mill waste recycling solution - Great value exists in the Paper Mill Waste recycling
With the raising awareness of protecting forest and grass, most paper mills choose to recycle waste paper as raw materials to produce paper. Various waste paper can be used to remake paper, like carton box, office documents, cardboard for package.etc. A report shows that a recycled paper mill with an annual output of 1 million 500 thousand tons will produce 180 thousand tons" paper making waste residue" a year. As there are some plastic, mental and grits in the waste paper, taking advantage of these kinds of...
Cut-Off Wall - Abandoned Mine Tailings Pond - Case Study
ProblemAt an abandoned mine in the Yukon Territory, mining for both Gold and Zinc took place until the mid 1950`s, with the processing of the ore taking place on the banks of an adjacent lake. Processing methods resulted in the creation of a large mine tailings pond that had high concentrations of iron, arsenic, zinc and lead. Spring runoff and summer rainfall then infiltrated through the pond resulting in contamination of the lake with heavy metals. The lake is a primary source of drinking water and the prevention...
UNTHA optimises WtE production and metal recycling at Turkish paper mill
An UNTHA shredder is now fully operational in Turkey’s first solid waste incineration plant. The single step XR3000C has transformed Modern Enerji’s approach to metal recycling, at the same time as boosting the production of Refuse Derived Fuel (RDF). The XR installation came about when Modern Enerji – part of Eren Holdings – sought a more effective technique for shredding its high calorific material stream. The team had been processing pulper ropes from the neighbouring paper mill,...
Intensified ribbon blending of melamine compounds cuts cycle times 25% for furniture molder
Melsur Corporation, the world`s leading supplier of hard plastic melamine school furniture, molds components from a mixture of resin, wood flour and pigments. Each of the 32 color variations, 30 products and custom designs must be blended individually, a process that can take up to four hours, depending on product. Anything less than empirically defined cycle times alters the final color and produces blemishes in the finished product.Melsur wanted to reduce blending times, but high mixing speed was not an option...
Biofuel - Energy Supplier of the Future?
Biofuel like biodiesel, plant oil, ethanol, bio methane or the synthetic biomass- to- liquid (BtL)- fuels everyone is talking about them. They are at present the only renewable alternative in the mobility sector and already today make up 6.1 % of the fuel consumption in Germany. However, in the past months and years biofuels had the reputation to generate a social- und environmental dilemma. For example, in developing countries large areas were cleared and used for sugar cane biofuel monocultures or similar and...
