AbstractThis manuscript deals with an optimized approach to work out the spindle diameter and distance of the spindle unit. Initially, the model for the evaluation of prescribed rigidity between the supports of computer numeric control (CNC) machining center has been designed and illustrated. The accuracy of the spindle rotation supported at two points has been investigated. Additionally, the critical speed of the spindle based on the projected methodology has been judged. Further, we computed the strength of the spindle in CNC machining center. Finally, real-time investigations have been made to validate the proposed approach.

Flexible manufacturing cell (FMC) was the extension of the CNC machining center,which consisted of three portions , a CNC machining center , an industrial robot and unified by a the background computer programmable control. In order to guarantee the rationality and feasibility of the automatic operation loading and unloading workpieces , the simulation object was based on the KUKA robot of flexible manufacturing cell in this paper, which based on MATLAB/GUI and combinated of VRML language and information transmission method development between MATLAB and the simulation system of flexible manufacturing unit. According to the set up parameters and angles, the model was implemented. Through the control panel and the robot's real-time interactive simulation, 3d visualization window can be real-time display of the robot simulation, and validated the path planning. According to the simulation results of the model , it could provide reference to the actual movement of the KUKA robot trajectory planning, provided the better fully automated feasibility analysis of flexible manufacturing cell, and proved the improvement of flexible manufacturing unit operation scientifically and reasonably.

Double-helical gears are usually manufactured using special type of machine tools, such as gear hobbing and shaping machines. In this paper, a manufacturing method of double-helical gears using a CNC machining center instead of the special type of machine tools is proposed. This manufacturing method has the following advantages: (i) the tooth surfaces can be modified arbitrarily, (ii) all we have to do in gear machining is only one machine setting, (iii) the hole and blank diameter and so on except the tooth surface can be also machined, and (iv) the auxiliary apparatus, special type of tools, and special type of machine tools are not needed. For this study, first the tooth profiles of the double-helical gear were modelled using a 3D computer-aided design system and the gear was machined using a CNC machining center based on a computer-aided manufacturing system. Next, the profile deviations, helix deviations, pitch deviations, and surface roughnesses of the manufactured double-helical gears were measured. Afterwards, the relationship between the tool wear and life time of the end mill were made clear. Finally, this manufacturing method was applied to the gears for a double-helical gear pump. As a result, the validity and effectiveness of the manufacturing method of double-helical gears using a CNC machining center were confirmed.
