Purpose: An integrated CAD/CAM system for milling operations has been developed which helps designers to solve machining problems at the design stage. Design/methodology/approach: A methodology has been employed which provides all necessary information for machining products automatically. Use of these system results in reduced machining leadtimes and cost through designing machinable component...

Lightweight structures are an important element in today’s production industry. For the multi-axis milling of these structures some aspects have to be considered to achieve a good surface quality and to prevent damaging the milling machine during the machining process. In this article methods to determine suitable feed rates for the milling process, to identify parts of the workpiece with too m...

An end milling process is widely used in fabrication of complex contours and shape parts at high spindle speeds. Many researchers try to investigate one of important aspect, which come across during machining is the self exited chatter vibration which causes severe damage of the tool and quality of the machined surface. The present work is focused on the Magneto-Rheological Damping effect on st...

In machining to improve machinability, productivity and to extend tool life coolants and lubricants where used .Increasing industry the use of cutting fluids subsequently increasing this leads in reduce of living conditions nearby future all the governments recommend the manufacturers to reduce the usage of toxicity cutting fluids. Still research for dry machining challenge is exiting for the i...

Subtractive manufacturing (CNC machining) has high quality of geometric and material properties but is slow, costly and infeasible in some cases; additive manufacturing (RP) is just the opposite. Total automation and hence speed is achieved in RP by compromising on quality. Hybrid Layered Manufacturing (HLM) developed at IIT Bombay combines the best features of both these approaches. It uses ar...

G-code, another name of ISO6983, has been a popular commanding language for operating machine tools. This Gcode, however, limits the usage of today's fast evolving high-performance hardware. For intelligent machines, the communications between machine and CAD/CAM departments become important, but the loss of information during generating G-code makes the production department isolated. The new ...

This research work highlights the effects of acoustic emission (AE) signals emitted during the milling of H13 tool steel as an important parameter in the identification of tool wear. These generated AE signals provide information on the chip formation, wear, fracture and general deformation. Furthermore, it is aimed at implementing an online monitoring system for machine tools, using a sensor f...

Based on characteristic of autobody panel, data processing and reconstructing curved surface are described in detail by the example of autobody panels making. The points cloud is obtained by laser three-dimensional scanner, and is treated by surfser software. Autobody reconstructing surfaces is achieved by reverse engineering. Fininshed surface model is made out of wax and processed in CNC mill...

Bimetallic parts are used in many industries for weight and cost reduction of workpieces working under high loads and wear. One application for this type of composite material is in automotive industry. In this work the tool wear and cutting forces in the face milling of bimetallic parts made of aluminum and cast iron were investigated. A356 and GG25 alloys that are common materials for bimetal...

The traditional method for creating 3D landscape models is manually assembled plaster models. For the Jurassic Coast model I have employed a CNC computer numerically controlled milling machine. CNC (Computer Numerically Controlled) routing is a way of machining an object directly from (Computer Aided Design) data with a sharp, fast moving tool bit. I am working with geospatial data of the Juras...
