Fused Filament Fabri ion FFF of Metal-Ceramic Components The best fitting results for stainless steel sintering behavior were obtained with an attrition milling time of 180 minutes and a planetary ball mill PBM milling time of 240 minutes. Figure 5 shows a SEM-image of the untreated powder left , the deformed particles after the attrition milling middle , and the chopped particles after the PBM

Cutting Forces and Vibrations During Ball End Milling of In this model, a set of curvilinear coordinate system normal to the ball envelope is used to specify the resultant force acting on the i-th infinitesimal segment of the cutting edge. Figure 1 depicts cutting forces acting on the cutter and tool†s coordinates for a ball end mill. Fig. 1. Geometry and tool coordinates for a ball milling
