The proposed Six Sigma methodology has been successfully implemented in a grinding process of automotive manufacturing organization; in future, the approach could be applied in different industrial sectors with addition of new tools and techniques for improving its effectiveness.
This paper presents the step-by-step application of the Six Sigma DMAIC (Deﬁne–Measure–Analyse–Improve–control) approach to eliminate the defects in a ﬁne grinding process of an automotive company. This has helped to reduce defects in the process and thereby improve productivity and on time delivery to customer.

when grinding with larger values of the angle 13, a very stiff system could be worse than a compliant system. The conclusion that it may be desirable to introduce some compliance into the system needs to be treated with caution. The depth of cut continuously fluctuates due to the "regenerative effect" inherent to the process. In centerless ...

TO DIAMOND GRINDING Because the grinding process adds to the cost of producing ground-face block, manufacturers are concerned with minimizing grinding costs to be more competitive. Recently, several block producers have significantly l o w e r ed production costs, while improving product quality, using a new diamond-grinding process.
Gear lapping is the process of imparting a very fine finish and high degree of accuracy to gear teeth, by using a lapping tool and applying a fine-grained abrasive between a work material and a closely fitting surface, called a lapping plate.
The Grinding Process Grinding is a material removal and surface generation process used to shape and finish components made of metals and other materials. The precision and surface finish obtained through grinding can be up to ten times better than with either turning or milling. Grinding employs an abrasive product, usually a rotating wheel ...
The grinding wheel and the metalworking fluid, however, are variables that can be modified. And given the right combination, they can significantly improve the grinding process by improving part quality, increasing production, and decreasing overall cost.
intelligence methods to supervise and control the cylindrical traverse grinding process. Also the metal removal rate can be maximized in very few grinding passes. Choi et al  states that, coolant promotes the effects of lubrication, cooling and penetration, but it contains chlorine, sulfur and phosphorus to improve the grinding
a suitable manufacturing process is state-of-the-art. Beyond the generation of microgeometrical structures, the present study investigates the potential of chemical alterations, i.e., metalworking ﬂuid additives engaged in a grinding process to improve the chemical surface properties of machined gear synchronizations.
Robotizing the grinding process became with a great interest. In order to robotize this process, we proposed a solution that helps improve the surface roughness and reduce grinding vibrations. Active strategies are the best suited strategy for this application.
In the centerless grinding process, the angles at which the wheels contact the part are critical to achieving the proper roundness and tolerance. Generally, the centers of the regulating and grinding wheels are set at the same height on the machine, and the center of the workpiece is situated higher. However, if the workpiece is set too high ...

Blog: How to improve your grinding process. All mining sites have their own objectives and face different challenges. The process, the material to be processed and the equipment is unique for each site. Understanding those objectives and challenges is crucial when developing a supporting product.
Apr 02, 2015· Improved process stability, independent of operator intervention. And all this while achieving modest increases in per-machine productivity. Better dressing frequently results in systematic bore grinding process improvements because the sharper wheels minimize lateral forces that can cause vibration, quill deflection, and uneven wheel wear.
Grinding is a finishing process used to improve surface finish, abrade hard materials, and tighten the tolerance on flat and cylindrical surfaces by removing a small amount of material. Information in this section is organized according to the subcategory links in the menu bar to the left.
Watching important parameters allows you to improve profitability by making necessary changes. Before getting into the four categories that influence grinding efficiency, it's important to know how the grinding process works. When you're using a grinding machine, three interactions are happening at the same time: cutting, plowing and sliding.
to improve the grinding process. Power = Heat = Temperature = Burn During grinding, virtually all of the power to drive the spindle motor is converted into heat . For a given set of grinding parameters, heat is directly proportional to temperature  according to: The partition ratio, or the fraction of grinding power which enters the
Process mechanics. Since honing stones look similar to grinding wheels, it is tempting to think of honing as a form of low-stock removal grinding. Instead, it is better to think of it as a self-truing grinding process. In grinding, the wheel follows a simple path.
When its rate is increased, whether by applying larger increments per stroke in traverse grinding, or by increasing the speed of the continual cross-slide advance in plunge grinding, higher stock removal will result, thereby improving the effectiveness of the process.
major process elements that can be easily varied and controlled. It also describes techniques for measuring the performance of the grinding machines and its evaluation process. It describes Data Collection characteristics and analysis techniques used to improve the productivity.
Grinding Theory and Process Engineering Classes are available to get your company up to speed on the best information and approaches to improving your grinding processes. We can work together to select course modules that meet your company's needs.
