at this study, after designing and manufacturing a rotary tool, its machining parameters and their effects on surface roughness of aluminum alloy of al99 which  is one of the most consumable alloys in aerospace industry, is  studied and optimized. first, the rotary tool is designed and manufactred. then according to taguchi method, the experiments have been designed to record surface roughness,...

Detection of tool breakage is very important for automated machining operations. This paper presents a negative-selection algorithm for tool breakage detection. The method is inspired by the defense mechanism of the immune system, which discriminates between self and non-self. Here self is deened to be normal cutting operations and non-self is any deviation beyond allowable variation of the cut...

Titanium alloys are widely used in many areas, such as aerospace, biomedical, and automotive industries, due to their excellent chemical physical properties. However, its difficult-to-machine characteristic causes various problems the machining process, serious tool wear elastic deformation of workpieces. To achieve high efficiency quality titanium alloy materials, this paper conducted an exper...

This paper presents a description of how CNC milling can be used to rapidly machine a variety of parts with minimal human intervention for process planning. The methodology presented uses a layer-based approach (like traditional rapid prototyping) for the rapid, semi-automatic machining of common manufactured part geometries in a variety of materials. Parts are machined using a plurality of 21⁄...

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 ...
