For robot architecture, the mechanical casting defect of entrapped air bubble against static and fatigue strength were investigated by numerical and experimental. According to practical experience and FEM model, the safety factor and fatigue life with casting defect condition was deteriorated 44% and 99.5%, respectively. Furthermore, the NDT technique was adopted for an inspection of quality.

This paper aims to develop the design theory and analysis tool for hydrostatic slide tables using capillary in precision surface grinding machine. Basic performance characteristics of hydrostatic bearing pads using recess-type such as, load capacity, stiffness, damping, flow rate of oil, pumping power, friction power loss, etc. will be analyzed in this study. The design theory and analysis tool development of the hydrostatic slide table will be based on considering a single bearing pad, which constitutes then the basic, modular element to be used to construct any desired table/slide configuration. Once the characteristics of one pad are modelled and analyzed satisfactory in function of the design parameters, the obtained results can be used in other dedicated design environments to simulate the performance behaviour of any integrated system of interest, which comprises a number of different pads in a hydrostatic slide table.
