  • In this study an experimental investigation was conducted to assesment of cutting ability for CBN ball end-milling, STD11 and NAK80 materials. The cutting force and surface roughness of the work-pieces were obtained in machining center. The assessment of CBN tools were inspected through the tool dynamotor and SEM. When $30^{\circ}$ negative rake angle, the wear and cutting force were good, surface roughness was better at cutting fluid during CBN cutting.

  • This paper discusses two user-friendly reliability techniques that could be implemented easily using the ubiquitous EXCEL. The techniques are First-Order Reliability Method with non-Gaussian random variables expressed using Hermite polynomials and collocation-based stochastic response surface method. It is believed that ease of implementation would popularize use of reliability-based design in practice.
