A method for designing and acquiring a machine by the use of benchmark machines which perform a certain function or operation in a desired manner. Certain locations are analyzed on the benchmark machines and vibration measurements and/or impact tests conducted on these locations which allow certain attributes or characteristics to be respectively assigned to these locations. The new machine is designed to improve upon these respective characteristics or attributes, thereby performing the operation in a highly accurate and reliable manner.

Method for designing and acquiring a machining system based upon performance characteristics

A method that simultaneously monitors and captures vibration acceleration signals at locations comprising at least one site sourcing environmental excitations and a target site, which target site is selected from a planned machinery foundation site or one or more sites interfacing between elements of machinery to be placed on such foundation; extracting amplitude and frequency data from the frequency representations of the domains of such signals; quantifying displacement excitations from such data at such locations; and providing transmissivity ratios along the vibration path by summing the displacement excitations at different frequencies at each of the locations and then ratioing the sum at either the planned machinery foundation site or at a selected joint site with the sum at the environmental excitation site, thereby indicating the relative vibration stiffness between such sites. Such transmissivity ratios can then be used to modify the design of the proposed foundation, and/or the design of interfacing elements of the machine.
