This proposed method has to design and fabricate the Multipurpose Jig and Fixture, for that component which has been to reduce the manufacturing cycle time. When the component produced on a small size previously this is to produces the large quantities of requirements. The selective components requires for machining operations such as step milling, angle milling & boring and reaming. The few op...

Abstract Deep hole drilling processes for high-alloyed materials are characterised by worn guide pads and chatter vibrations. In order to increase feed rates, process stability bore quality in STS deep drilling, various investigations were carried out with adjustments the tool. First, a new chain production of tribologically optimised their effects on pad shape is described detail. The results ...

CollabCAD is an indigenous 3D CAD/CAM software system for collaborative design and development of Industrial Designs for strategic use. This work is for CAM module of the indigenous software, in which the development of post-processor is the task that is accomplished. The CAD model is created in CollabCAD and the required tool path was produced in a generic format known as Cutter Location (CL) ...

Utilization is one of the main managerial factors that is applied for construction process analysis well. It directly affects the project duration and construction costs. Therefore, a utilization study in tunneling projects is essential. In this work, the utilization of an earth pressure balance Tunnel Boring Machine (TBM) in Tabriz urban railway project was studied using the Monte Carlo simula...

As the main cutting tool of Tunnel Boring Machine (TBM) for rock-breaking, rock-breaking efficiency TBM disc cutters directly affects TBM’s boring speed, which in turn overall progress tunnelling project. Therefore, a simple and accurate evaluation method is an essential prerequisite to improve performance TBM. In this paper, classical force prediction equations were summarized applicability ea...

Abstract Ansys software is used to simulate the welding process of boring bar new cylinder head machine. The indirect coupling method analyze temperature field, then stress field and deformation. It found that for double support structure, highest occurs at outer stiffened plate small diameter end, lowest both ends inner structure. deformation whole structure mainly comes from axial deformation...
