INTRODUCTION The manufacturing of complex shaped microstructures on microsystem parts in brittle materials provides a high geometrical accuracy [1]. This requirement can only be met by using microgrinding processes. There, metal bonded diamond grinding tools offer a remarkable potential due to their favorable wear behavior [2]. However, the dressing of complex microprofiles on these tools is no...

In this current era of competitive machinery productions, the industries are designed to place more emphasis on the product quality and reduction of cost whilst abiding by the pollution-preventing policy. In attempting to delve into the concerns, the industries are aware that the effectiveness of existing lubrication systems must be improved to achieve power-efficient and pollutionpreventing ma...

The beneficiation process contains a number of links which are closely related to all aspects of the quality of products in a process which has a direct impact on the next one, thus influencing the product quality of all processes. Grinding operations form a critical stage in the middle position of the beneficiation process and is the most important part. Grinding operations here refers to ore ...

Thermal pretreatment or torrefaction of biomass under anoxic condition can produce an energy dense and consistent quality solid biomass fuel for combustion and co-firing applications. This paper investigates the fuel characteristics and grindability of pine chips and logging residues torrefied at temperatures ranging from 225 °C to 300 °C and 30 min residence time. Grinding performance of torre...

This paper discusses the application of an eco-grinding system using a mixture of compressed cold air and vegetable oil. The feasibility of the system was assessed using the surface grinding of plain carbon steel 1045 with a BWA60MVA1 wheel. The investigation showed that cold air can be used to suppress surface burning under certain material removal rates and has an advantage of reduced grindin...

The hardened alpha-case (alpha-case) layer inevitably forms on the surface of titanium castings when prepared by investment casting. Because the hardness of the alpha-case is incomparable to that of the interior structure, the perception exists that the alpha-case is difficult to remove during cutting, grinding and polishing. Grindability (ease of grinding) of cast cpTi and cast Ti-6Al-4V was e...

Abstract Aerostatic spindles are used in precision grinding applications requiring high stiffness and very low error motions (5 to 25 nm). Forces generated during precision grinding are small and present challenges for accurate and reliable process monitoring. These challenges are met by incorporating non-contact displacement sensors into an aerostatic spindle that are calibrated to measure gri...

Successful of grinding in practice is highly depending on the level of expertise of the machinist and engineer. Knowledge Management might offer a strategy to keep the valuable knowledge. The main objective of Knowledge Management (KM) is to manage knowledge process, the knowledge itself could not be managed, what can be managed is the knowledge gathering, storing and organizing, retrieving, an...

The model of surface grinding with a nanoparticle jet flow of MQL was established. The surface grinding thermal stress of three workpiece materials, namely, 45 Steel, 2Cr13, and nano-ZrO2 dental ceramic, were numerically simulated. Results show that dry grinding generates larger tensile stress, whereas MQL grinding generates larger compressive stress. The finished surface of workpiece produces ...
