N2 - Reconfigurable machine tools (RMT) are the core facility of reconfigurable manufacturing systems (RMS), and structure design is the fundamental research involving RMT. The existing prototypes of RMT are limited to a specific part family, which suffers from reconfiguration difficulty and module sustainability issues. Therefore, a design philosophy of RMT for multi-part families with new design principles based on reconfigurability is proposed in this paper. Modularity and integrability are the basic principles, scalability, convertibility, and customization are the primary design principles, and reusability and symmetry are the auxiliary design principles. By implementing the new design principles, a two-step design method of RMT is proposed. First, a basic three-main-module structure, including the base, function arm, and workstation, is created. Second, customized components are selected to customize the functions for a specific part family, which can be reconfigured to meet the demand of other part families using other customized components. A prototype of RMT illustrates the proposed design philosophy to specify the basic three-main-module structure. The basic configurations of the RMT prototype are given, as well. The reconfigurability of the RMT prototype is analyzed from the perspectives of scalability, convertibility, and reconfiguration time. Based on topology optimization, the performance of the RMT prototype is improved. The case study implements milling and turning functions, demonstrating the practicality of the proposed design philosophy, where the processing of typical parts is also analyzed. Furthermore, the reconfiguration process among multi-part families is discussed in the case study.
