Jan 01, 1999· This kinematic analysis is done for the example of a double-side fine grinding machine, type Duomat ZL 700, Hahn & Kolb , Schorndorf (now Stahli Lapp-Technik , Schonaich). The outer pin circle of this machine is fixed, whereas the two grinding wheels and the inner pin circle can be driven individually.
Material grinding machines can be applied to various industrial processes. As mentioned, the mining industry commonly uses milling machines to extract desired elements from the less desirable surrounding materials; however, grinding machines can be used for a variety of purposes outside of the mining industry as well.

In this paper, screw theory is utilized to derive the kinematics of a six-axis EDM machine consisting of three translational axes and three rotational axes. With the rigid transformation of each axis described by an exponential of a twist, the overall kinematics is obtained as a product of exponentials of twists.
Machining is any of various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material-removal process. The processes that have this common theme, controlled material removal, are today collectively known as subtractive manufacturing, in distinction from processes of controlled material addition, which are known as additive manufacturing.
Jan 01, 2015· 9.3. Kinematics of the ELID grinding with lapping kinematics. The study will be conducted on the Melchiorre Machine (210-3P). This machine has two lower wheels and one upper spindle. Because this experiment is for a single-side grinding, some modifications needed to be implemented. Trajectory
The basic process parameters in grinding processes are the cutting speed v c, the feed velocity v f, the depth of cut a e, and the width of cut a p (see Fig. 1, see also Denkena and Tönshoff 2011).The cutting speed is in general equal to the circumferential speed of the grinding wheel.
Taking the double grinding wheel crankshaft follow-up grinder as the research object, the motion errors of the machine tool are obtained by analyzing the motion relations among the moving bodies. Based on the kinematics theory of multi-body system, the kinematics model of the whole machine …
