“…Work hardening (like beating a singing piece of metal on smithy's iron) has similarly been used for a significant long time by metalworkers to bring partitions into materials, extending their yield characteristics. Turning of tempered steel straight forwardly without work solidifying of metal will prompt loss of its properties [2]. Consequently, going with the strain-solidifying components was followed to make the tempered steel material to distort plastically.…”

The formability of the austenitic grade of low Ni-treated steels (SSLNA) was examined by metal turning measure. The treated steel items are considered for choice as prepared with consumption safe properties. In monetary terms, they can contend with greater expense designing metals and amalgams dependent on nickel or titanium, while offering a scope of consumption opposing properties reasonable for a wide scope of utilizations. In this investigation, the austenitic grade of low nickel-tempered steel material was spun and met with the crack. The deformation of spinning is done on the various angles with change in percentage of thickness from 14 to 80%. The characterization of the fracture has been concentrated by the field emission scanning electron microscope to notice the morphological states of the material. The 12.5 mm WD of sample provides clear rupture in the grain boundaries of microstructure. The essential investigation was inspected by energy-dispersive spectroscopy. A solid connection was seen with both examinations approving the presence of voids in the material that causes the remaining anxieties which prompts the break on the SSLNA material.

A computer numerical control (CNC) multi-pass spinning solution to a center lathe retrofit

This paper suggests a typical scheme for substantially low cost machine upgrading with regard to research and manufacturing activities through the integration of mechanical, electronic and software technologies. Computer numerical controlled (CNC) multi-pass spinning process is considered state-of-the-art nowadays in critical applications such as aerospace and automotive industries but equipment cost is still an issue. For the sake of novelty, accuracy and repeatability of spun products, a conventional lathe machine has been converted into CNC spin-forming machine by retrofitting to generate automatic tool paths in two axes for multi-pass spinning. Actuators and sensors necessary to provide controlled motion of mechanical elements such as mandrel, roller, and holder are selected to cope with the requirements of this incremental metal forming process. A CNC controller is integrated to the system with software to generate the tool path and G-code required for producing cups using the retrofitted machine. Rotational speeds together with longitudinal and transverse axes movements are calibrated. Backlash in power screws is evaluated and considered in the displacement control. Different tool paths including involute path can be generated using the developed control system. The machine has been used successfully to produce cups with high processing speeds and superior surface quality to that reported in the available literature. Based on experimental investigation under lubricated condition, the geometrical and surface quality with productivity was improved and an optimum exists at 0.6 mm/rev. feed ratio, 200 RPM mandrel rotational speed, and seven spin-forming passes.
