“…Kroll [10] analyzed an X ray inspection machines mainly along the X axis. Erkorkmaz [11] analyzed a precision X-Y working stage along the X,Y and Z axis respectively, while Eisenbies [12] analyzed a CMM machine and Sun [13] analyzed an ultraprecision flycutting machine tool along the same axis direction. Error budget analysis on five-axis machine are done by Cheng [14], Brecher [15] and Treib [16] ,but their analysis are also along the X,Y and Z axis respectively.…”

Abstract:Customer-oriented design is very important for machine tool manufacturers to win competition in the market. Mechanical parts with complicated sculptured surface are widely utilized in mechanical systems such as automobiles, aircrafts and wind turbines, and they are often machined by five-axis machine tools with high precision requirements. However traditional machine tool design has not accounted for the varied machining errors in producing complex sculptured surface, which leads to inferior performance. To address this challenge, a novel machining error synthesis model is proposed in this paper for accuracy optimization in designing general five-axis machine tools used for making various sculptured surfaces. The new synthesis model bridges between surface machining profile error and the machine tool accuracy, and it is constructed by integrating a generic machine tool volumetric error model and two new surface machining error production models. The synthesis model is then applied as a constraint in machine tool accuracy design optimization. Also a tolerance-cost function is formulated to construct the objective function, and a meta-heuristic algorithm is developed to implement the optimization. All these modeling and optimization methods are validated by one case study.

“…Thus, an analysis of errors is essential to all manufacturing processes to validate their suitability for a selected design. Previous studies have focused on the error budgeting multi-axis lasers [5] and polar coordinate laser writing systems [6]. The polar coordinate laser writing system uses a rotary encoder to coordinate the motorised air-bearing spindle with the purpose of achieving writing accuracy in the order of 0.1 μm at rotational speed of up to 800 rpm.…”

“…Erkorkmaz et al [9] carried out the error budget for the X-Y stage of precision machine tool, where the geometrical error, dynamic error, servo error and thermal error were mainly regarded. Cheng et al [10] employed the error allocation for the optimum selection of key motion components and its position accuracy allocation when designing a desktop multiaxis laser machine for micro tool fabrications. Lin and Ehmann [11] discussed the tolerance distribution among the links and joints of a multi-axis machine.…”

Ultra-precision machine tool is the most important physical tool to machining the workpiece with the frequency domain error requirement, in the design process of which the dynamic accuracy design (DAD) is indispensable and the related research is rarely available. In light of above reasons, a DAD method of ultra-precision machine tool is proposed in this paper, which is based on the frequency domain error allocation. The basic procedure and enabling knowledge of the DAD method is introduced. The application case of DAD method in the ultra-precision flycutting machine tool for KDP crystal machining is described to show the procedure detailedly. In this case, the KDP workpiece surface has the requirements in four different spatial frequency bands, and the emphasis for this study is put on the middle-frequency band with the PSD specifications. The results of the application case basically show the feasibility of the proposed DAD method. The DAD method of ultra-precision machine tool can effectively minimize the technical risk and improve the machining reliability of the designed machine tool. This paper will play an important role in the design and manufacture of new ultra-precision machine tool.
