Design and Implementation of a Data Acquisition and Processing Method for Precisely Calculating the Location Errors of Five-Axis CNC Machine Tools

Abstract

Support taking through bracing or leaning while performing manual tasks is known to enhance the capability of the operator. However, simulation of this natural and biomechanically signicant behaviour in a DHM environment is either not possible or calls for signicant expertise and planning on the part of the simulation engineer. While manual simulation is time-consuming and error-prone, an algorithmic procedure is expected to enhance eciency and versatility in the simulation of diverse work environments and what-if scenarios. This paper presents a computational method for determining the location of and reaction at a support point on a given surface that is most advantageous for performing a task. The method also evaluates dierent possible support combinations and the associated optimal postures for performing a given task. The method is illustrated through one-handed reach and supported sitting tasks. Given the task and the environment, the simulation is performed without the need for any user intervention.
