Milling is the mechanical process of removing material from a piece of stock through the use of a rapidly spinning circular milling tool in order to form some desired geometric shape. An important problem in computer-aided design and manufacturing is the automated generation of efficient milling plans for computerized numerically controlled (CNC) milling machines. Among the most common milling ...

We propose a new method for 5-axis flank computer numerically controlled (CNC) machining of screw rotors using conical tools. The flanks consist helical surfaces, which predetermines the motion milling tool and reduces search space positioning to only 4-parametric family, allows quick good initial positions given tool. initialize by looking at second order line contact between rotor. Several ar...

In this paper, a double-side milling method on spiral bevel gear is proposed. First, according to the tooth taper processed by method, influence of dedendum angle was researched. Taking cut parameters into comprehensive consideration, geometric were designed through inclination root line and modified mean point in which machine setting calculated selected. Only met meshing equation, error press...
