Wear Condition

Stamping is one of the most widely used processes in the sheet metalworking industry. Because of the increasing demand for a faster process, ensuring that the stamping process is conducted without compromising quality is crucial. The tool used in the stamping process is crucial to the efficiency of the process; therefore, effective monitoring of the tool health condition is essential for detecting stamping defects. In this study, vibration measurement was used to monitor the stamping process and tool health. A system was developed for capturing signals in the stamping process, and each stamping cycle was selected through template matching. A one-dimensional (1D) convolutional neural network (CNN) was developed to classify the tool wear condition. The results revealed that the 1D CNN architecture a yielded a high accuracy (>99%) and fast adaptability among different models.

Width Measurements

Despite the advantages of advanced high strength steels (AHSS), their stamping into functional lightweight parts demands prolonged die life, which necessitates the use of alternative substrates, coating materials, and/or surface conditioning to minimize and delay the die wear. In order to avoid frequent die replacement and surface quality problems on the stamped parts, the metalworking industry has been investigating various approaches such as reducing/refining the carbide particles, adding alloying elements, and elevating the hardness and toughness values for both substrate materials and coatings. The objective of this work was to investigate the effects of different coatings on the wear behavior of a some selected tool steel materials (die sample of interest) against two different AHSS sheet blanks through a cylinder-on-flat type reciprocating test method. After wear tests, both die sample and sheet blank surface were microscopically examined. Wear resistance of the slider was quantified from wear scar width measurements. Results showed that TD and CVD coated die samples performed better than the two other PVD coated samples.

Ball On Disc

The production processes of the metalworking industry are usually carried out in the presence of oxygen. Par ticularly due to surface oxidation on tools and parts during production under normal atmosphere, high wear is observed in tribological systems. The focus of these investigations is the question to what extent the ambient atmosphere has an influence on the tribological system. For this purpose, the identification and characterization of wear mechanisms in an oxygen-free atmosphere is of high relevance. To analyse the influence of the ambi ent atmosphere on the tribological properties of titanium, ball-on-disc investigations are carried out on a univer sal tribometer (UMT) in an air, argon and silane-anodized atmosphere. By suppressing the oxidation under ex clusion of oxygen, a reduction of the tribochemical wear could be shown, which is accompanied by a reduction of the wear volume by a Factor of 4.5. However, due to the adhesion of both friction partners, which already occurs at low temperatures, caused by the omission of the friction-reducing cover layers, the friction coefficient increased. In addition, novel alloy formations at the interfaces were detected and analysed.

Wavelet Image

According to the unique advantages in image processing combining wavelet and fractal and the different ways of combination, a super-resolution image processing methods are proposed. The methods are characterized by combining the wavelet transform, Wavelet Image Interpolation and FBM Fractal Image interpolation in a certain way to achieve super-resolution image reconstruction. Through processing MAG welding pool images polluted by noises seriously, the results show that: the method proposed in this paper, compared with the method based on wavelet bilinear interpolation, not only effectively raises MAG welding image resolution, but also PSNR of reconstruction images are enhanced 21.1049 dB.

Development Paths

There typical EWC development paths can he singled out. To a certain extent these paths already exist. They can also he described as development stages of individual EWCs: the EWC with an exclusively national frame of reference: the EWC which is taking on an international quality, but focusses on the industrial relations within the parent company's country: the EWC deliberately working to develop a supranational collective identity with a European underpinning amongst members tending towards equality. Four dimensions can be analytically distinguished in this regard: time, money, information and power. The better the EWC can equip itself in terms of these four “claims”, the greater is the chance of developing a European identity and ability to act effectively. Naturally, the reverse is also true. The four claims are here differentiated in relation to EWCs, based on empirical knowledge mainly derived from two projects in which the author was or is a participant. As examples, the cases of Hoechst (chemical industry), Schmalbach-Lubeca (metalworking industry), AXA/UAP (insurance) and Kredietbank (baiting) are succinctly described. The evaluation looks selectively at a few other relevant empirical project results without detailed substantiation. The results are generalised in terms of a “good EWC practice”. The final part deals with the main subjects of the forthcoming revision of the EWC Directive, which focuses on improvement of the four main claims of EWCs' resource situation.
