Sensitvity analysis of rotating auxiliary components of a high-speed spindle shaft assembly
Machine tool spindles, complex dynamic systems under thermal growth, are significantly influenced by the shaft assembly's dimensions, including the spindle shaft and various press-fit auxiliary elements.

International Journal of Machine Tools and Manufacture, 2013 Abstract The cutting process stability depends on machine tool dynamics that is strongly influenced by the tool. Receptance coupling substructure analysis (RCSA) can be used to estimate the tool tip dynamic compliance and consequently the chatter free cutting conditions when the machine is equipped with a tool that has not been previously tested ...

Fixed Boundaries Receptance Coupling Substructure Analysis for Tool Point Dynamics Prediction
Advanced Materials Research, 2011 In many applications, chatter free machining is limited by the flexibility of the tool. Estimation of that capacity requires to obtain the dynamic transfer function at the tool tip. Experimental calculation of that Frequency Response Function (FRF) is a time consuming process, because it must be done using an impact test for any combination of tool ...

A new receptance coupling substructure analysis methodology to predict tool tip dynamics
International Journal of Machine Tools and Manufacture, 2018 Abstract Tool tip frequency response function (FRF) is essential for chatter stability diagram in machining. But new modal tests are required for different tool-holder-spindle assemblies. To avoid these tests, receptance coupling substructure analysis (RCSA) method has been developed.

Three-Component Receptance Coupling Substructure Analysis for Tool Point Dynamics Prediction
Journal of Manufacturing Science and Engineering, Transactions of the ASME, 2005 In this paper we present the second generation receptance coupling substructure analysis (RCSA) method, which is used to predict the tool point response for high-speed machining applications. This method divides the spindle-holder-tool assembly into three substructures: the spindle-holder base; the extended holder; and the tool.

International Journal of Machine Tools and Manufacture, 2018 Abstract Machine tool components are connected by joints that provide relative motion between contact interfaces. These joints add flexibility to the load path from the tool tip to the foundation and, therefore, the correct determination of joint properties becomes a crucial step if the whole machine performance is to be analyzed.

Identification of Toolholder-Spindle Joint Based on Receptance Coupling Substructure Analysis
Applied Mechanics and Materials, 2013Stiffness identification of toolholder-spindle joint is a basic work for machine tool dynamic research. In this paper, an identification method based on receptance coupling substructure analysis is described. Once the frequency response functions of the toolholder, the spindle and the toolholder-spindle assembly are obtained, the analytical stiffness ...
