Automated recognition of features from CAD models has been attempted for a wide range of application domains. In this paper we address the problem of representing and recognizing the complete class of features in alternative interpretations for a given design. We present a methodology for recognizing a class of machinable features and addressing the computational problems posed by the existence...

The aim of this research work is to evaluate the effects of coolant including nano- powder material for the cooling purpose in milling process and comparing the results with the conventional coolant. Generation heat and weak heat transfer reduces the tool life and also deteriorate surface roughness during milling operation. To overcome this problem, it is necessary to use coolant for cooling as...

Manufacturing technologies are becoming continuously more diversified over the years. The increasing use of robots for various applications such as assembling, painting, welding has also affected the field of machining. Machining robots can deal with larger workspaces than conventional machine-tools at a lower cost and thus represent a very promising alternative for machining applications. Furt...

The installation of suitable sensors close to the tool tip on milling centres is not possible in industrial environments. It is therefore necessary to design virtual sensors for these machines to perform online fault detection in many industrial tasks. This paper presents a virtual sensor for online fault detection of multitooth tools based on a bayesian classifier. The device that performs thi...

In this work, the Prediction of acceleration amplitude and surface roughness of Aluminium alloy (Al6061), reinforced with 15% Silicon Carbide particle (SiCp) metal matrix composites, has been made in the end milling process considering various machining parameters. The MMC was considered the difficult to machining due its reinforcement hardness and nature of abrasive element and the prediction ...

This paper proposes a new method to find the equations of transformation matrix for the rotation angles of the two rotational axes and the coordinates of the three linear axes of an orthogonal multi-axis milling machine. This approach provides intuitive physical meanings for rotation angles of multi-axis machines, which can be used to evaluate the accuracy of the conversion from CL data to NC d...

This paper describes the implementation of an integrated monitoring system for a CNC machine tool and its machining processes such as drilling, milling, turning and grinding. The monitoring system uses a variety of sensors such as force, torque, vibration, acoustic emission, and temperature to monitor the machining processes and the physical condition of the machine tool. The major aim is to im...

In precision machining processes, major problems can be related to the condition of the cutting tool. Online tool condition monitoring is hence of great industrial interest. To empower the machining system with adaptivity and intelligence required, an embedded tool condition monitoring system (eTCM) has been developed for online detection of machining process abnormities such as tool breaking, ...

This paper presents a volume-based haptic rendering method for a haptic shape modeling system based on simulated milling process. Previous proposals on point-based and ray-based haptic rendering methods cannot provide the force feedback in a milling process. The method proposed in this paper adopts a volumetric force model in material removal process. The force is calculated based on the relati...
