The application of variable helical end mills to the milling titanium alloys can suppress regeneration effect during machining process and ensure stability milling. However, due their special geometry, characteristics are also different. In this paper, alloy with a helix mill is taken as research object, force, deeply studied. Firstly, feed per tooth cutting thickness model were established, fo...

Manufacturing molds for plastic parts injection are a particular machining domain, where challenging materials, like AISI P20 steel, forced to satisfy the highest surface quality requirements. Before mirror polishing, milling operation is common and task due drilling with same tool. Thus, special cutting tools, asymmetric indexable type, often used. This tool presents two geometrically equal po...

Computer-Aided Manufacturing (CAM) occupies an increasingly important role in engineering with all it has to offer in terms of new possibilities and improving designer/manufacturer productivity. The present study addresses machining of free-form surfaces on a 3-axis NCmachine tool. There have recently been a large number of studies devoted to planning tool paths on free-form surfaceswith variou...

In waterjet and laser milling, material is removed from a solid surface in a succession of layers to create a new shape, in a depth-controlled manner. The inverse problem consists of defining the control parameters, in particular, the two-dimensional beam path, to arrive at a prescribed freeform surface. Waterjet milling (WJM) and pulsed laser ablation (PLA) are studied in this paper, since a g...

Metal matrix composites have been increasingly used as materials for components in automotive and aerospace industries because of their improved properties compared with non-reinforced alloys. During machining the selection of appropriate machining parameters to produce job for desired surface roughness is of great concern considering the economy of manufacturing process. In this study, a surfa...
