An investigation is reported on the wear of single-layer electroplated cubic boron nitride (CBN) grinding wheels and how process affects wheel topography behavior. Internal cylindrical straight surface experiments were conducted over a wide range conditions hardened bearing steel with containing different abrasive grain sizes. The radial was characterized in each case by an initial transient at progressively decreasing rate to steady-state regime nearly constant until end life. Wheel during...
Orbital drilling of composites was investigated to observe hole surface integrity in terms roughness, delamination, burning, and geometric accuracy. Experiments were conducted with a brazed single layer diamond tool ball-end geometry drill 220 holes. Cutting forces temperatures measured. Micro-observations made the surface. The results showed that increased sharply during first 44 holes followed by gradual rise. Part varied between 98-184°C. Surface roughness Ra from 13-17 μm. Almost 99%...
This paper is concerned with the experimental investigations for prediction of grinding force distribution in wheel and workpiece contact zone. A new approach was developed to predict using horizontal vertical forces measured while a shorter length along pass. Straight surface experiments were conducted straight oil as fluid on nickel-based alloy (IN718) 60-grit 150 mm diameter electroplated CBN implement this investigate effects speeds workspeeds distributions. Grinding power measured. It...
Deformation is the most direct indicator of structural state changes in arch dams. Therefore, numerous deformation monitoring points are typically arranged on dams to obtain data from each point. Considering complex relationships between at point, this study focuses internal and information fusion within dam. The Pearson correlation coefficient used as a similarity index determine significant linear correlations measuring points. Ward’s cluster analysis method then applied group these based...
An analysis for a robotized grinding process of aerospace Titanium high pressure compressor blades was performed. In this process, the blade grabbed on robotic arm. A Scotch-Brite wheel, pneumatic actuator, used to grind edges blades. The objective research work identify major factors that influence accuracy and final part quality. This achieved by analyzing dynamic characteristics wheel motor as well frequency response functions (FRF) were identified at different robot configurations...
