This paper presents a new three pass forming approach using incremental sheet forming (ISF) for the manufacture of a trumpet bell. Brass instrument bells are traditionally manufactured using artisanal methods (cutting, hammering, spinning and finishing) which are labour intensive but deliver superior quality instruments. The aim of this work was to achieve comparable levels of control using ISF. A series of 27 trials were undertaken to establish optimum set up, forming strategy and tool selectio...

Process and product fingerprints are unique process and product characterisation parameters, respectively. They need to be controlled to ensure that manufactured parts are within their specifications to achieve the required functions. The process and product fingerprints are developed to reduce production time and efforts for metrology and process optimisation. The existing methods to identify process and product fingerprints are usually developed for particular machining processes. They are oft...

Abstract null null Blown powder directed energy deposition of SS316L powder is carried out on various substrate surface conditions of SS304 such as cleaned, sand blasted, milled, oily, cold galvanised and painted to study their influence on the process. High-speed imaging is used for process observation and the deposited tracks are analysed qualitatively and quantitatively using surface images, cross sectional macrographs and x-ray images. Frames from high-speed imaging reveal the removal of add...

Abstract null null This paper presents the results of an in-depth study of the plasma-chemical etching (PCE) process of single-crystal silicon carbide (SiC) in SF6/O2 inductively coupled plasma (ICP). Using the method of optical emission spectroscopy (OES) we have examined the influence of RF power, bias voltage, pressure in the reaction chamber, and gas mixture composition on SiC PCE as well as the applicability of the OES technique for optimization and monitoring of SiC dry etching process in ...

Abstract null null A damage evolution law is proposed to consider the frictional behavior within an Eulerian material after full damage as a Lagrangian material, where the mesh explicitly describes the newly born interface interactions. This approach is prominent for simulating severe plastic deformation (SPD) processes during which material separation can occur. Among these, orthogonal cutting represents the simplest process for comparison with the simulation because it offers accessibility for...

Abstract null null A methodology based on finite element computations is proposed to predict the galling onset of aluminium alloys in cold forming. The methodology assumes that galling starts as soon as a finite element in the area of contact has reached a critical damage. The damage is calculated using Xue's model, which takes into account the effect of tangential stresses on the damage evolution. The tangential stress is calculated using Wilson's mixed lubrication model taking into account the...

Abstract null null Finding appropriate machine setting parameters in injection molding remains a difficult task due to the highly nonlinear process behavior. Artificial neural networks are a well-suited machine learning method for modelling injection molding processes, however, it is costly and therefore industrially unattractive to generate a sufficient amount of process samples for model training. Therefore, transfer learning is proposed as an approach to reuse already collected data from diff...

Abstract null null The change of the gap width is one of the important factors that affect the quality of K-TIG welding, and it is difficult to keep the gap consistent in the welding of large workpieces. Vision technology is a reliable method of weld pool monitoring. To avoid the influence of the strong arc of K-TIG welding, this paper designed a real-time HDR system and based on which, a weld pool and keyhole geometric feature extraction algorithm was proposed. The designed HDR system includes ...

Abstract null null Conventional cutting fluids as coolants and lubricants are being widely used in various machining processes, but these cutting fluids give rise to biological and environmental problems. The advantages of implanting micro texture on macroscopic cutting tools have been proved widely in implementing sustainable machining. But seldom studies focused on preparing micro texture on the surface of micro end mill with diameter less than 1 mm. In this study, an attempt has been made to ...

Abstract null null Poor surface traits, short insert life, high manufacturing costs, and low productivity are associated with the machining of nickel alloys. Cutting fluids have well-known positive and negative effects on machinability performance. As a result, the machining industry has developed green cutting environments such as vegetable oil assisted minimum quantity lubrication (MQL) and cryogenic cooling. Despite the fact that MQL and cryogenic approaches can replace mineral oil-based floo...
