Glass fiber reinforced plastics (GFRPs) composite is considered to be an alternative to heavy exortic materials. According to the need for accurate machining of composites has increased enormously. During machining, the obtaining cutting force is an important aspect. The present investigation deals with the study and development of a cutting force prediction model for the machining of unidirectional glass fiber reinforced plastics (UD-GFRP) composite using regression modeling and optimization by simulated annealing. The process parameters considered include cutting speed, feed rate and depth of cut. The predicted values radial cutting force model is compared with the experimental values. The results of prediction are quite close with the experimental values. The influences of different parameters in machining of UD-GFRP composite have been analyzed.

The dynamic mechanical characteristics of excessively heavy-duty cutting were analyzed based on the cutting experiments with 2.25Cr-1Mo-0.25V steel used in hydrogenated cylindrical shells. By investigating the influence of dynamic mechanical characteristics on the tools’ failure in limited heavy-duty cutting processes, the model of dynamic shearing force in the cutting area was established. However, the experimental results showed that the dynamic shear flow stress in the cutting area greatly influenced the tools’ fatigue. The heavy-duty cutting tool was damaged in the form of a shearing fracture. Through a comprehensive analysis of the theory, the critical condition of the tools’ fracture under extreme loading was established.

The new technology of clean burning of coal and simultaneously converting the resultants into value-added products is to add a special admixture in coal and grind them together to form affinity granules, which are sprayed into the boiler of the power plant for affinity calcination. The technology, while ensuring power and heat supply, decreases the contents of carbon residue, NOx and CO2 raises the activity of pulverized coal ashes, conducts soild desulfurization, and turns all the solid resultants into quality cement clinkers in the quick burning and quick cooling boiler, thus eliminating gas and solid pollution without producing secondary pollution, and realizing clean production.

Goethite is a metals-rich residue that occurs during zinc production. The feasibility of metal recovery from goethite has been demonstrated, but is not economically viable on an industrial scale. Therefore, goethite is landfilled with considerable economic costs and environmental risks. The goal of this study is to evaluate the environmental performance of a new valorization strategy for goethite residues from zinc production, with the aims of: ① recovering the valuable zinc contained in the goethite and ② avoiding the landfilling of goethite by producing a clean byproduct. The presented goethite valorization strategy consists of a sequence of two processes: ① plasma fuming and ② inorganic polymerization of the fumed slag. Plasma fuming recovers the valuable metals by fuming the goethite. The metals-free fumed slag undergoes a process of inorganic polymerization to form inorganic polymers, that can be used as a novel building material, as an alternative to ordinary Portland cement (OPC)-based concrete. Lifecycle assessment (LCA) is used to compare the environmental performance of the inorganic polymer with the environmental performances of equivalent OPC-based concrete. The LCA results show the tradeoff between the environmental burdens of the fuming process and inorganic polymerization versus the environmental benefits of metal recovery, OPC concrete substitution, and the avoidance of goethite landfilling. The goethite-based inorganic polymers production shows better performances in several environmental impact categories, thanks to the avoided landfilling of goethite. However, in other environmental impact categories, such as global warming, the goethite valorization is strongly affected by the high-energy requirements of the plasma-fuming process, which represent the environmental hotspots of the proposed goethite recycling scheme. The key elements toward the sustainability of goethite valorization have been identified, and include the use of a clean electric mix, more effective control of the fumed gas emissions, and a reduced use of fumed slag through increased efficiency of the inorganic polymerization process.

Entering the era of 21st century, there are two characteristics bearing on thinkinginnovation and comprehension. As to innovation, how to exite creative-thinking is a warm problem. From the high level of philosophy—epistemology and relative-truth of materialist-dialectics, this paper shows that there is the duality of every form of thinking including the thinking of deduction and that of socalled fixed-accustoming. There is an existence of both non-creative thinking and creative thinking and under certain conditions non-creative thinking may be turn into creative thinking which can make new knowledge and innovative achievements. As to comprehension, there are many different opinions on how to define and classify thinkings. By combining physiology and psychology, this paper divides thinkings into 2 parts and 7 basic forms. Connecting dialectics with comprehension, the conclusions of this paper are shown： the duality of non-creative thinking and creative thinking, the duality of reasoning thinking and understanding thinking, the duality of original knowledge and new knowledge, the duality of idea and test-verification, the duality of discovery and invention, the duality of science (sense of truth ) and art (sense of beauty ). The last conclusion is expressed as an example of seeking the theory of a cross-course —industrial design, the main contents of which are technology, art and market. This theory of ID is the first advance in ID.
