Poor surface finish on die and mould transfers the bad quality to processed parts. High roughness is an example of that normally reduced by manual polishing after conventional milling machining process. Therefore, in order avoid disadvantages disadvantage machining, a sequence two operations proposed. The main operation run followed Rotary Ultrasonic Machining Assisted Milling (RUMAM). However,...

Metal forming processes, compared with machining ones, reduce production steps and increase manufacturing speed in addition to saving raw material. In this paper, forming process of column of a steering mechanism is investigated by finite element analyses and experimental tests; and optimum die design parameters are found. Forming process parameters including die opening angle, bearing length, ...

Correct selection of manufacturing condition is one of the most important aspects which should be considered in the majority of manufacturing processes,  particularly in the process related to advanced machining process like electrical discharge machining. In electrical discharge machining (EDM), dielectric fluid plays an important role since machining characteristics are greatly influenced by ...

Surface integrity (SI) plays a very important role in functional performance. It is dependent on a large number of machining parameters. The major concern of industry is to know which combination of machining parameters provides the best SI of machined components. Traditionally, surface roughness is considered to be the principal parameter to assess the SI of a machined part. However, residual ...

Wood and combinations of wood and plywood is the most traditional formwork in mould-based shaping of construction components. This kind of formwork usually doesn’t include curvatures, but favours straight lines and sharp corners yielding in angular shape concrete building blocks. In this paper we describe a novel robotized method for manufacturing individual concrete elements with specific shap...

Primljeno (Received): 2011-11-07 Prihvaćeno (Accepted): 2012-03-15 Original scientific paper Abstract: Pressure die casting is the method used for forcing molten metal into mould cavities under high pressure and at high speed (10 100 m.s). Pressure die casting is a highly productive method of casting parts with low dimensions tolerance and high surface quality. From the point of view of product...

Today's forging die manufacturing process must be adapted to several evolutions in machining process generation: CAD/CAM models, CAM software solutions and High Speed Machining (HSM). In this context, the adequacy between die shape and HSM process is in the core of machining preparation and process planning approaches. This paper deals with an original approach of machining preparation integrat...

Repair welding (RW) with wire cladding is a common procedure to extend the in-service life of heavily loaded tool parts for die and mould industries 1-5 . The main advantages of repair welding are short downtime and cost efficiency compared to production of new tool part. Repair welding in general lowers the tool cost in the final part and enables higher added value to the die casting and injec...

3-Axis Machines have traditionally been used for stamping die insert machining, which have less flexibility in terms of degrees of freedom. In order to cater to ever increasing demand for class-A surface finish of the inserts, additional operations such as hand grinding and polishing needs to be performed. It has been possible to manufacture the die inserts with 5 -axis machines, which in theor...
