Investigation of cycle time behavior in the robotic grinding process
Using the two equations that describe robot’s actual trajectory (Eq. 8 and Eq. 12), the equation for the face grinding process cycle time ( T) can be derived as a function of the process parameters, as follows: (13) T = t 1 τ ln Δ r 2 U 1 τ ( 1 e t 1 τ) where Δ r 2 in Eq. 13 denotes the width tolerance of the part.The static and dynamic performances of a machine tool structure are considered to constitute the primary factors affecting the load-carrying capacity, geometric accuracy and surface precision of the workpiece. The machining performance of a large machine tool under stable conditions is effectively determined by its dynamic response to Computation Free Full-Text Modeling the Static and

Experimental study on the reliability and the precision
The development of high-reliability, high-precision large-scale CNC ultra-precision grinding machines is essential for the efficient processing and manufacturing of large-diameter optical components. In this paper, we studied the reliability and the precision-maintenance of the ultra-precision grinding machine tool experimentally. First, the High-speed rail grinding is a unique passive grinding maintenance strategy that differs from conventional grinding techniques. Its grinding behavior is dependent on the relative motion between the grinding wheel and rail; hence, it possesses great speed and efficiency.

Grinding is a manufacturing process that belongs to the group of material removal processes. Material removal processes where a chip is formed can be subdivided into the groups of cutting processes and abrasive processes. Grinding differs from other abrasive processes such as honing, lapping, polishing, and blasting by the tools that are Tool forces are a decisive parameter for manual grinding with hand-held power tools, which can be used to determine the productivity, quality of the work result, vibration exposition, and tool lifetime. One approach to tool force determination is the prediction of tool forces via measured operating parameters of a hand-held power tool.
