The thesis compares oxidation and fusion laser cutting methods in the production of sheet components called Trager consoles. Individual methods of laser cutting are compared in terms of achieved quality and properties of cutting areas. Consequently, the effect of these properties on consecutive technological operations, which are mainly threading and pressing the nuts into components, are evaluated. In the experimental part of the thesis the roughness of cut surfaces was measured and the cuts were classified into quality classes according to the ČSN EN ISO 9013 standard. Metallographic samples were taken in order to measure hardness and determine its course in the direction from the cutting edge into the material. The metallographic samples were further used for capturing detailed images on the microscope and assessing the quality of nuts pressing. Afterwards, the cut moments affecting taps were measured in order to verify the impact of cutting edge properties on threading. These measurements provided sufficient data for comparing the influence of cutting edge properties in individual methods of laser cutting on consecutive operations. Finally, individual methods were compared in terms of production costs. According to all the data and the conclusions reached, fusion method was identified as the most suitable method of laser cutting for components manufacturing.

This study has been conducted with the aim to examine the extent of the heat affected zone in order to use laser cutting when making samples for tensile testing. When cutting with a laser the material absorbs heat energy from the laser beams which causes changes in the microstructure. The heat affected zone affects the properties of the materials, lowering the accuracy of the tensile test. Therefore, it is desired to know the extent of the heat affected zone in order to remove it before tensile testing. In this study two materials were used, the high strength steel Docol 1000DP and the duplex stainless steel LDX 2101. The materials were cut in the shape of dog bones for tensile testing using two different laser powers, 2500 W and 3500 W. The samples were cut with different cutting speeds, starting at lower cutting speed, increasing until the laser was unable to cut through. Thereafter, the heat affected zone, and the surface quality was examined. The results from this study showed that the heat affected zone decreases with increased cutting speed. When cutting with high cutting speeds in Docol 1000DP it is enough to turn away 0.30 mm in order to remove the heat affected zone with margin. Negligible difference in heat affected zone was observed between the samples cut with 2500 W and 3500 W. The heat affected zone in LDX 2101 was very small, in order of 50 μm, making it hard to measure. This resulted in no exact measurements being made. However, the heat affected zone was in the order of 50 μm for all samples, concluding that turning away 0.15 mm is sufficient to remove the heat affected zone with margin. No difference could be observed between the samples cut with a laser power of 2500 W or 3500 W. Common to both materials is that the amount of dross decreases with increased cutting speed. / Denna studie har utförts i syfte att undersöka utsträckningen av den värmepåverkade zonen för att kunna använda laserskärning för att skära prover till dragprovning. Ett problem med laserskärning är att metaller absorberar värmeenergin, vilket orsakar förändringar i mikrostrukturen. Denna värmepåverkade zon bör minimeras och avlägsnas från metallen, då det minskar kvalitén på proverna samt på dragprovningen. I denna studie har två material undersökts, det höghållfasta stålet Docol 1000DP och det duplexa rostfria stålet LDX 2101. Stålen skars ut i form av hundben för dragprovning med två olika effekter på lasern 2500 W och 3500 W. Proverna skars ut med olika skärhastigheter, började med lägre hastigheter och ökade sedan tills lasern inte längre kunde skära igenom materialet. Därefter undersöktes både den värmepåverkade zonen och kvaliteten på skärytan. Resultaten från denna studie visade att den värmepåverkade zonen minskar med ökad skärhastighet. Vid skärning i Docol 1000DP med höga skärhastigheter räcker det att avlägsna 0,30 mm för att ta bort den värmepåverkade zonen med marginal. Ingen skillnad i värmepåverkad zon observerades mellan proverna skurna med 2500 W och 3500 W vid skärning med högsta skärhastigheten för varje lasereffekt. Den värmepåverkade zonen i LDX 2101 var mycket liten, i storleksordningen 50 μm, vilket gjorde den svårt att mäta. Slutsatsen gav att det är tillräckligt att avlägsna 0,15 mm för att avlägsna den värmepåverkade zonen med marginal. Ingen skillnad kunde observeras mellan proverna skurna med en lasereffekt på 2500 W eller 3500 W. Gemensamt för båda materialen var att gradbildningen minskade med ökad skärhastighet.

This research details an investigation into processes employing laser technology to create design-led three-dimensional textiles. An analysis of historical and contemporary methods for making three-dimensional textiles categorises these as processes that construct a three-dimensional textile, processes that apply or remove material from an existing textile to generate three-dimensionality or processes that form an existing textile into a three-dimensional shape. Techniques used in these processes are a combination of joining, cutting, forming or embellishment. Laser processing is embedded in textile manufacturing for cutting and marking. This research develops three novel processes: laser-assisted template pleating which offers full design freedom and may be applied to both textile and non-textile materials. The language of origami is used to describe designs and inspire new design. laser pre-processing of cashmere cloth which facilitates surface patterning through laser interventions in the manufacturing cycle. laser sintering on textile substrates which applies additive manufacturing techniques to textiles for the generation of three-dimensional surface patterning and structures. A method is developed for determining optimum parameters for laser processing materials. It may be used by designers for parameter selection for processing new materials or parameter modification when working across systems.

Mainly used for decorative purpose in the textile industry, lace is a type of lightweight, openwork fabric. The process of lace manufacturing is complex but much of it has been highly automated with the advancement of modern technology. One exception is the lace cutting operation which is used to cut the wide lace webs (as wide as 3.8 m) knitted from automatic knitting machines into individual lace breadths. Currently, lace cutting IS carried out by skilled operators or a low speed mechanical cutting system, leading to high cost and increased product lead times. Therefore the lace cutting operation has become a bottleneck of the whole process oflace manufacturing and its automation is highly desired. Based on the combination of machine vision and laser cutting technology, two automatic lace cutting systems have been developed in Loughborough University, which have fully demonstrated the feasibility of replacing the slow and expensive traditional lace cutting methods. However, the edge quality of the lace cut by these systems is not satisfactory enough to meet the requirements of demanding lace markets. In this thesis, based on the investigation of the effect of handling tension on lace cutting edge quality and the microstructure of lace, a strategic lace cutting solution has been presented. The cutting strategy is aimed at tensioning and exposing the loop thread by strategically tensioning and cutting individual threads. The loop thread is considered critical to cutting lace with a high quality finish. To automatically implement the cutting strategy, a machine vision system has been developed. An automatic lace transport and tensioning rig has been designed and manufactured. The long term aim of this rig is to be able to transport and tension lace continuously for lace cutting and apply localised tension on individual threads with the vision system providing feedback for tension control. The work in this thesis has been limited to manual adjustment of the rig to prove the initial ideas for this concept. An integrated vision guided, pulsed laser cutting system for lace cutting has been developed, based on which two types of representative lace have been cut. According to the assessment results of using a combination of user trials, microscopic and newly developed measurement techniques, the lace cut by this newly developed system has shown significant improvement in cutting edge quality, when compared to the lace cut by the previous laser cutting systems.

Carbon fiber-reinforced plastics (CFRPs) have gained widespread popularity as a lightweight, high-strength alternative to traditional materials. The unique anisotropic properties of CFRP make processing difficult, especially using conventional methods. This study investigates laser cutting by ablation as an alternative by comparing two near-infrared laser systems to a typical mechanical machining process. This research has potential applications in the automotive and aerospace industries, where CFRPs are particularly desirable for weight savings and fuel efficiency. First, a CNC mill was used to study the effects of process parameters and tool design on machining quality. Despite high productivity and flexible tooling, mechanical drilling suffers from machining defects that could compromise structural performance of a CFRP component. Rotational feed rate was shown to be the primary factor in determining the axial thrust force, which correlated with the extent of delamination and peeling. Experimental results concluded that machining quality could be improved using a non-contact laser-based material removal mechanism. Laser machining was investigated first with a Yb:YAG fiber laser system, operated in either continuous wave or pulse-modulated mode, for both cross-ply and woven CFRP. For the first time, energy density was used as a control variable to account for changes in process parameters, predicting a logarithmic relationship with machining results attributable to plasma shielding effects. Relevant process parameters included operation mode, laser power, pulse overlap, and cross-ply surface fiber orientation, all of which showed a significant impact on single-pass machining quality. High pulse frequency was required to successfully ablate woven CFRP at the weave boundaries, possibly due to matrix absorption dynamics. Overall, the Yb:YAG fiber laser system showed improved performance over mechanical machining. However, microsecond pulses cause extensive thermal damage and low ablation rates due to long laser-material interaction time and low power intensity. Next, laser machining was investigated using a high-energy nanosecond-pulsed Nd:YAG NIR laser operating in either Q-Switch or Long Pulse mode. This research demonstrates for the first time that keyhole-mode cutting can be achieved for CFRP materials using a high-energy nanosecond laser with long-duration pulsing. It is also shown that short-duration Q-Switch mode results in an ineffective cutting performance for CFRP, likely due to laser-induced optical breakdown. At sufficiently high power intensity, it is hypothesized that the resulting plasma absorbs a significant portion of the incoming laser energy by the inverse Bremsstrahlung mechanism. In Long Pulse mode, multi-pass line and contour cutting experiments are further performed to investigate the effect of laser processing parameters on thermal damage and machined surface integrity. A logarithmic trend was observed for machining results, attributable to plasma shielding similar to microsecond fiber laser results. Cutting depth data was used to estimate the ablation threshold of Hexcel IM7 and AS4 fiber types. Drilling results show that a 2.2 mm thick cross-ply CFRP panel can be cut through using about 6 laser passes, and a high-quality machined surface can be produced with a limited heat-affected zone and little fiber pull-out using inert assist gas. In general, high-energy Long Pulse laser machining achieved superior performance due to shorter pulse duration and higher power intensity, resulting in significantly higher ablation rates. The successful outcomes from this work provide the key to enable an efficient high-quality laser machining process for CFRP materials.

Through manipulation of the materials and creation of sculptural forms, the knowledge in textile design was used to develop alternative methods for working with materials of animal origin. The project touches the issue of consumption by accentuating the fascinating features of animal materials and proposes a way of taking care of materials looked upon as disposals. It questions how we value what resources we have in our surroundings and how we use them. Or more important – how we are not using them.

Estas espécies foram caracterizadas no que tange às suas propriedades físicas de teor de umidade, densidades aparente e básica, e estabilidade dimensional. Foram também realizadas análises de espectroscopia por energia dispersiva de raios-X (EDS) para a determinação da composição química qualitativa e semiquantitativa das espécies. Os ensaios de aplicação da tecnologia de corte a laser nas espécies de madeira foram realizados em amostras de espessuras variadas: lâminas de 1 a 5 mm. As análises dos parâmetros do processo de corte a laser mais adequados para cada espécie de madeira e espessura de lâmina foram feitas com o auxílio de imagens de micro-estereoscopia. Dentre os parâmetros definidos estão a potência do feixe de laser, a aceleração e as velocidades de movimentação dos bocais de corte, o fluxo de saída do jato de ar, e a distância focal. Para a verificação da aplicabilidade destes parâmetros em marchetaria foram executados cinco painéis, variando a espessura das lâminas e a complexidade dos desenhos reproduzidos. As composições dos painéis foram baseadas no trabalho do artista gráfico M. C. Escher.
