OHNS steel after cylindrical grinding process is proposed to be studied using L9 orthogonal array having three levels and three input parameters. Work speed, depth of cut and number of pass are considered as the input parameters for this study and the response parameters are minimum surface roughness and minimum.
The prepared work mounted between the centers of the lathe machine chosen. Cylindrical grinding with traverse feed is used for finishing components turned on a lathe. The surface finish obtained on the heavy duty lathe was modeled against various parameters, such as work speed; traverse feed rate and depth of cut.
However, the composite sum of these grinding parameters creates static and dynamic forces. It is obvious that the roundness error and surface roughness are created by many parameters, but in this study, only the effects of the depth of cut, work speed and feed rate which create the grinding forces in cylindrical grinding are.
The high-precision 5-axis CNC grinding machine of the 325linear series is extremely flexible and universal. . The high output of the grinding spindle of up to 15 kW at a speed of 12,000 min-1 enables high material removal volumes and is . Cylindrical grinding operations such as cylindrical contour surface grinding or axial.
Grinding wheels for cylindrical and roll grinding. . Cylindrical grinding may include all outside diameter grinding, even though the finished workpiece is not a cylinder. The workpiece . One must consider the material of workpiece, machine condition and speeds etc., to have a correct choice of grinding wheel specification.

Conversely, reducing the speed of the wheel will increase the chip. GRINDING WHEEL. CONTACT SURFACE. It is at the contact surface between.
Surface grinding is the most common of the grinding operations. It is a finishing process that uses a rotating abrasive wheel to smooth the flat surface of metallic or nonmetallic materials to give them a more refined look by removing the oxide layer and impurities on work piece surfaces. This will also attain a desired surface.
Cylindrical grinding (also called center-type grinding) is used to grind the cylindrical surfaces and shoulders of the workpiece. The workpiece is mounted on centers and rotated by a device known as a drive dog or center driver. The abrasive wheel and the workpiece are rotated by separate motors and at different speeds.
Results show that variation in the grinding wheel and work piece speeds, . the machine tool-work piece system, for cylindrical plunge grinding process. A functional mathematical model for the grinder equipped with hydrostatic bearing on the . The rotational speeds for the work piece and the grinding wheel are Ωw and Ωg.
