Sculptured surfaces are relatively difficult to machine due to their complex geometry. Sculptured surface machining primarily has two stages, the first being roughing and the other being finishing. The current work focuses on generating tool paths for the finishing operation. Given any arbitrary sculptured surface, G&M machine codes have been generated to machine that surface using ball-end mil...

Finishing is a basic requirement for obtaining the required surface quality in production of various components used many industries. A relatively new finishing process, called magnetic abrasive finishing, complex shaped surfaces. This article presents latest developments polishing and describes results obtained by research scientists based on their experiments field polishing.

In a world of ever-increasing electronic component complexity and pin count requirements for component packaging, focus is once again on the age-old question of "How do we preserve solderable surfaces between PWB manufacturing and assembly?" PCB manufacturers today are faced with the decision of which surface finish to offer their customers, while their customers struggle with choosing the best...

One of the newly developed methods for obtaining super finished surfaces for freeform is Magnetorheological finishing (MRF). MRF is an advanced finishing process in which the grinding force is controlled by magnetic field. The material removal in MRF is governed by the magnetorheological fluid which mainly consists of carbonyl iron (CI), abrasives particles, carrier fluids and additives. MRF pr...

This report focuses on the surface finishing of metals or metal finishing as it is usually called. Because of the wide range of techniques used and the similarity between some of the techniques, a classification system was devised to organize the presentation of the material. Metal finishing activities have been divided into (1) pretreatments, which include cleaning and surface preparation, (2 ...

ABSRACT High speed machining is a relatively new production technology that allows higher productivity, excellent surface finish and good dimensional accuracy in the manufacturing process. Therefore these technologies have considerable advantages over traditional machining technologies. Instead of conventional machining chain that consists of roughing in soft state + semi fininshing + hardening...

Finishing and polishing of composite restorative materials plays a major role in success and longevity of restoration. Aim of this study is to analyze the finishing and polishing procedures by measuring the surface roughness of the novel resin composites using profilometer and scanning electron microscopy before and after subjection to three body wear simulation method .The four posterior compo...

One of the challenges in the printing industry is the presence of extra lines in printing design. This problem is due to the improper surface roughness of carved cylinders. This research endeavors to specify and optimize the effective parameters on the surface roughness of chrome coated printing cylinders in the finishing process that is done using a finish star machine. Investigated parameters...

OBJECTIVES The aim of this study was to investigate the effects of fiber-reinforced resin burs on the surface roughness of a nanofilled composite. METHODS Average surface roughness values (Ra, mum) were measured using a surface profilometer and surface textures after finishing procedures were evaluated using a scanning electron microscope (SEM). Thirty cylindrical specimens were prepared usin...
