Abstract:
To realise the high cutting speeds required in wood machining for a productive cutting process, high-speed spindles are used especially in CNC machining centres. The high rotational speed during operation, however, results in great centrifugal forces at the tool. Particularly unbalance here leads to a great loading of the spindle bearing as well as to reduced occupational safety. Unlike metal removal, the machining of wood and engineered wood products is subject to other requirements regarding the process parameters, such as e.g. higher cutting speeds or material removal rates. For that reason

Abstract:
This paper presents a machining accuracy analysis for computer-aided fixture design verification. While discussing the utilization of CNC machine tools and machining centers, machining errors are described in terms of deterministic and random components and analyzed on the bases of their sources, where high machining accuracy and multi-operation under a single setup become major characteristics of manufacturing systems. In machining processes, a resultant dimension may be generated in terms of several relevant dimensions. The dependency of variation among these dimensions is examined and the r

Abstract:
In the multivariate design mode, based on the effective parallel design facilities, the rational choice of the design of the two-support spindle for the machining center is the main aim of this article. A modified scheme for selecting a spindle unit is proposed, which reflects the procedure for the formation of its main components: "Representations on the Spindle Unit Variations" and "Representations on the Designer's preferences". A concept is introduced and a component of the selection scheme is described: "Procedural model", which makes it possible to realize the mechanism of forming prefer

Purpose This paper aims to investigate the performance and positioning accuracy of computer numerical controlled (CNC) feed drive system using a ball screw-based pre-loading impact factor. Design/methodology/approach Initially, axial displacement of support bearings has been computed in relation to the different preload values. Among the computed values, a basic rule equation has been developed for the calculation of elongation in the bearings. The value of displacements computed from the developed equation has been considered as a pre-loading value, and its behavior on the feed drive system h
