Manufacturing is about constant improvement. Just as machine shops work hard to improve the speed at which they get parts out the door without losing quality, OEMs have thousands of people dedicated to improving manufacturing equipment to make their customers' jobs easier.
In this paper, a novel bipod parallel grinder with four controlled degrees of freedom is introduced. The moving platform of this 2-leg parallel grinder can always keep moving in horizontal plane by means of four-parallelogram mechanism (Π joints). The closed-form solutions of forward and inverse kinematics are derived...3.1 INTRODUCTION. Material removal by grinding occurs mainly by a chip formation process, similar to that of other machining methods such as turning or milling, but on a much finer scale. While the cutting-tool geometry and its interaction with the workpiece is well defined for most machining processes, the situation for grinding is not readily ...
The precise face grinding and lapping technology with abrasive or abrasive tool has been widely used in the field of the precise manufacture and ultraprecise manufacture. It has become an essential technology in the manufacture of many components. The planetary lapping machine is typical equipment for face grinding or lapping process. And the relative motions between the …...lindrical grinding machine (Figure 1(c)) with a rotating stone disc for tool or weapon sharpening or grinding. With the advent of machines and as they evolved, especially since the use of electricity, machine kinematics and fundamental kinematic cutting schemes got more complicated (a) (b) (c)
The grinding kinematics trajectory and condition are analyzed based on the structure of the Biglide parallel machine. ... drill point grinding machine based on …...A machine vies (made from ferromagnetic steel or cast iron) placed on the magnetic chuck can be used to hold non-ferromagnetic work pieces if only a magnetic chuck is available. Factors to consider in surface. grinding are the material of the grinding wheel and the material of the piece being worked on.
Volumetric accuracy is one among several factors used to assess the quality and performance of a machine tool. Besides its use for assessing the performance of machine tool, the estimation of volumetric accuracy of a machine tool can also be used for compensation of volumetric errors or to study the influence of individual errors on the accuracy of machine tool. …...A kinematic analysis and mechanism description of a biglide parallel grinder with six-controlled degree of freedom is presented in this paper. In comparison with hexapod machines, the mechanical structure and motion of this biglide parallel grinder are simple. Therefore, it is easy for this biglide parallel grinder to accomplish real-time control.

Kinematics of the grinding system has been analyzed. To get a continuous and smooth fresh face over the rock, grinding trajectory of the grinding wheel has been discussed and planned...Furthermore, the modelling of the grinding machine strongly depends on the current process setup, e.g., the grinding kinematics, the material and shape of workpiece, and the properties of the grinding wheel. Within this article different modelling approaches describing the different components of the grinding machine are presented.
Kinematic Pairs: Kinematic pair is a joint of 2 links having relative motion between them. Kinematic pairs can be classified in several ways: 1. By the type of contact between the elements, line, point, or surface. 2. By the number …...Abstract - Grinding is one of the most important manufacturing process for high precision parts. Grinding force has a direct influence on grinding wheel wear, grinding temperature, the surface quality of the work piece and the design of machine tool component. Also, the cutting force is
Recently developed computer-controlled twist drill grinding machines have allowed the production of precisely defined points of widely different shapes. The design methodology used for these machines has yielded machines that have up to seven separate axes. This paper shows that in a machine where all the axes can move simultaneously only two rotations and …...Full Article.
