Design engineers can benefit by learning to use the programming tools of CAD systems. It is possible to increase their productivity and implement their ideas effectively. Moreover, they can focus on the important product development stage instead of consuming time in routine tasks. In the light of these considerations, the current paper presents the possibilities that derive from the use of the programming resources that are available in different CAD systems, and especially the ones related to product design and fabrication. Two CAD-based applications were developed via such techniques, and the case studies found in this work prove their validity and usefulness. Well-known, commercially available CAD systems were used for these purposes, namely SolidWorks™ and Rhino™. The development of the applications was achieved via the CAD-based programming tools such as the application programming interface of SolidWorks™, by using Visual Basic for Applications programming language, and Python™, a textual programming language combined with Rhino™ 3D modeling tools.

As modern industry advances, the demand for more time and cost effective machining is rising. In order to achieve high levels of standard during machining it is necessary to employ sophisticated techniques for precise prediction of various important parameters that relate to the machining processes. Such technique is the implementation of finite element modelling (FEM) which can become a valuable tool for researchers and industry engineers alike. In this work, the 3D modelling of Al7075-T6 drilling process with solid carbide tooling is being presented. DEFORM3D™ finite element analysis (FEA) software was utilized for simulating the drilling process based on frequently used cutting conditions; cutting speed of 100m/min and feed of 0.15mm/rev, 0.20mm/rev and 0.25mm/rev respectively. In order to approximate the complex phenomena that occur during drilling, the most critical factors were considered in the presented model such as the developed friction, heat transfer and damage interaction between the tool and the workpiece. Additionally, a validation of the generated results for thrust force and torque was performed by comparing the simulated results with experimental data. Three drilling experiments were carried out with the aid of a CNC machining center and a four component dynamometer in order to acquire the experimental values of thrust force and torque. Most of the simulations yielded results in accordance to the experimental ones with the agreement percentage reaching 95% in most cases for both the thrust force and torque, confirming the validity of the models and the accuracy of the simulated results.

Jewel design is performed for many years and the designers and manufacturers follow a variety of inspirations. Traditionally the designs are generated based on the artistic sense of the creator, while at the same time a number of manufacturing restrictions apply. Nowadays, a series of advanced Computer Aided Design, CAD based tools are available in order to generate impressive concepts. Although, it is possible for designers to interface a CAD system and implement their design digitally, some prefer to use the programming capabilities offered by the CAD software developers. This is the way forward, in order to create unusual geometries for the jewellery industry and at the same time to develop the capability for generating a complete family of geometries that can satisfy even the most demanding customer. In the current paper, the latest approach is presented together with a case study.

Traditionally interior design is based on the inspiration generated by the designer who acts as an artist and engineer at the same time. Today, a number of digitally developed forms can be used with an aim to offer unusual geometries. Computational design technologies can be used in order to fully automate the generation of a design based on a series of parameters that can be altered within specific limits. In such a way, families of forms and proposals are made available and more opportunities for products dealing with interior design can be produced. These forms require the use of modern 3D printing technologies for their construction due to their geometrical complexity and their digital development. In the present paper, computational design will be presented together with a case study in the area of interior design.

There are numerous engineering applications where Glass Fiber Reinforced Polymer (GFRP) composite tubes are utilized, such as desalination plants, power transmission systems, and paper mill, as well as marine, industries. Some type of machining is required for those various applications either for joining or fitting procedures. Machining of GFRP has certain difficulties that may damage the tube itself because of fiber delamination and pull out, as well as matrix deboning. Additionally, short machining tool life may be encountered while the formation of powder like chips maybe relatively hazardous. The present paper investigates the effect of process parameters for surface roughness of glass fiber-reinforced polymer composite pipes manufactured using the filament winding process. Experiments were conducted based on the high-speed turning Computer Numerical Control (CNC) machine using Poly-Crystalline Diamond (PCD) tool. The process parameters considered were cutting speed, feed, and depth of cut. Mathematical models for the surface roughness were developed based on the experimental results, and Analysis of Variance (ANOVA) has been performed with a confidence level of 95% for validation of the models.

In this study, the development of a 3D Finite Element (FE) model for the turning of AISI-D3 with ceramic tooling is presented, with respect to four levels of cutting speed, feed, and depth of cut. The Taguchi method was employed in order to create the orthogonal array according to the variables involved in the study, reducing this way the number of the required simulation runs. Moreover, the possibility of developing a prediction model based on well-established statistical tools such as the Response Surface Methodology (RSM) and the Analysis of Variance (ANOVA) was examined, in order to further investigate the relationship between the cutting speed, feed, and depth of cut, as well as their influence on the produced force components. The findings of this study point out an increased correlation between the experimental results and the simulated ones, with a relative error below 10% for most tests. Similarly, the values derived from the developed statistical model indicate a strong agreement with the equivalent numerical values due to the verified adequacy of the statistical model.

Oral care products and especially toothpastes, are vital for the human daily hygiene. Nowadays tooth brushing is, without a doubt, an integral part of pre-ventative dentistry, but on the other hand the extensive use of toothpastes has a great impact on the environment. Traditional toothpaste tubes have many negative aspects, in terms of usage and recycling. Their modest size, mixed and merged materials, remnant toothpaste inside toothpaste tubes and other tube based containers, make them difficult to disassemble and recycling almost impossible. The main objective of this study, is to investi-gate the disadvantages of the toothpaste packaging and the proposal of new innovative packaging solutions, which will not only reduce the environmental impact that traditional toothpaste tubes cause, but will also be user-friendly. In this paper, a combination of literature survey and market research is being presented. Finally, based on the findings and well-established techniques, a number of innovative, user and environmental friendly toothpaste packaging is proposed.

The present paper examines the application of a holistic product design approach from the Design Thinking point of view. The Design Thinking process follows a number of steps with an aim to develop product design visual concepts around users’ experiences and their needs. The presented case study is focused to the modern jewellery design era. The proposed design was developed by using a series of design thinking methodologies (empathy maps, persona, product design) and creative tools (mind-maps, moodboards, sketches, storyboards, and prototyping). Furthermore, through this holistic design approach an alternative version of future jewelries is achieved, while at the same time it embodies novel technologies and web-based applications. The paper discusses the potentials for reimagining the jewellery products in relation to the Design Thinking Process and CAD-based tools at the same time. Finally, the proposed products provide a novel framework of art and new technology methods for extensive production of innovative art-based products.

Nowadays more and more computer-aided technologies and computational techniques are applied to product design. Jewelry belongs to those products. Jewelry is considered as part of human civilization and adopted to human’s needs. In recent years, computational design is applied in order to overcome the limitations of traditional CAD systems, when reaching an increased level of complexity and geometrical controls. Computational design supports the evolution of creative design and develops models as a form of the computational exploration. Furthermore, additive manufacturing (AM) pieces of equipment are widely used to create models and prototype parts in various applications. AM plays an important role, when developing jewelry models, as it is utilized with an aim to produce high-quality models in rather reduced numbers and complex shapes. In the current paper, a computer-based design tool was applied in order to develop algorithms for the generation of new artistic forms for the design of a set of jewelry. Then, Stereolithography (SLA) technique is chosen for the prototype models construction.

The resources of modern Finite Element Analysis (FEA) software provide engineers with powerful mechanisms that can be used to investigate numerous machining processes with satisfying results. Nevertheless, the success of a simulation, especially in three dimensions, relies heavily on the accuracy of the cutting tool models that are implemented in the analyses. With this in mind, the present paper presents an application developed via Computer-Aided Design (CAD) programming that enables the automated design of accurate cutting tool models that can be used in 3D turning simulations. The presented application was developed with the aid of the programming resources of a commercially available CAD system. Moreover, the parametric design methodology was employed in order to design the tools according to the appropriate standards. Concluding, a sample tool model was tested by performing a number of machining simulations based on typical cutting parameters. The yielded results were then compared to experimental values of the generated machining force components for validation. The findings of the study prove the functionality of the tool models since a high level of agreement occurred between the acquired numerical results and the experimental ones.

The present study investigated the performance of three ceramic inserts in terms of the micro-geometry (nose radius and cutting edge type) with the aid of a 3D finite element (FE) model. A set of nine simulation runs was performed according to three levels of cutting speed and feed rate with respect to a predefined depth of cut and tool nose radius. The yielded results were compared to the experimental values that were acquired at identical cutting conditions as the simulated ones for verification purposes. Consequently, two more sets of nine simulations each were carried out so that a total of 27 turning simulation runs would adduce. The two extra sets corresponded to the same cutting conditions, but to different cutting tools (with varied nose radius). Moreover, a prediction model was established based on statistical methodologies such as the response surface methodology (RSM) and the analysis of variance (ANOVA), further investigating the relationship between the critical parameters (cutting speed, feed rate, and nose radius) and their influence on the generated turning force components. The comparison between the experimental values of the cutting force components and the simulated ones demonstrated an increased correlation that exceeded 89%. Similarly, the values derived from the statistical model were in compliance with the equivalent FE model values due to the verified adequacy.

Due to the fact that simulation of drilling was added in commercial finite element analysis (FEA) software only recently, 3D finite element modelling is an invaluable asset during related researches. The present study employs 3D FEA to model the drilling process of Al7075-T6 alloy with solid carbide tooling, investigates important phenomena that occur during drilling and finally compares the simulated results with experimental data. A number of simulations were performed with DEFORM3D™ software at different cutting conditions; cutting speed of 50m/min, 100m/min, 150m/min and feed of 0.15mm/rev, 0.20mm/rev, 0.25mm/rev. The proposed model takes into consideration certain aspects like damage initiation and evolution of the material, contact interface between the drill bit and the workpiece and standard boundary conditions. Eventually, the acquired numerical data for thrust force were compared to the experimental results for the same cutting conditions and parameters. To obtain the experimental data, a series of nine drilling tests were performed. Upon validation of the numerical data, the temperature distribution on the tool tip – workpiece interface, as well as the chip morphology (shape and curling radius) were determined. Results showed a good agreement between the numerical and the experimental data. Specifically, thrust force and chip morphology exhibited an agreement of about 95% and 90% respectively, which confirms the potential of 3D FEA implementation on machining investigations.

Like most machining processes, drilling is affected by many parameters such as the tool diameter, the cutting speed and feed. The current research investigates the possibility of developing a finite element modelling based prediction model for the generated thrust force during drilling of Al7075-T6 with solid carbide tools. A total of 27 drilling experiments were carried out in order to examine the interaction between three key parameters and their effect on thrust force. In addition, simulations of the experiments were realized with the use of DEFORM3D™ software in order to obtain the necessary numerical data. Finally, a comparison was made between the experimental and the numerical results to verify that reliable modelling is feasible. The mathematical model was acquired with the use of response surface methodology and the verification of the adequacy of the model was performed through an analysis of variance. The majority of the simulations yielded results in agreement with the experimental results at around 95% and the derived model offered an accuracy of 5.9%.

This paper investigates the quality performance of FDM 3D printed models with thin walls. The design of experiments method (DOE) was used and nine models of the same size were fabricated in a low-cost 3D printer using polylactic acid (PLA) material. Two limited studied parameters were considered (extraction temperature and wall thickness), each one having three levels. External X and Y dimensions were measured using a micrometer, as well as four surface roughness parameters (Ra, Rz, Rt, Rsm) with a surface tester. Two optimization techniques (the Taguchi approach and Grey relational analysis) were utilized along with statistical analysis to examine how the temperature and wall thickness affect the dimensional accuracy and the surface quality of the parts. The results showed that high extraction temperature and median wall thickness values optimize both dimensional accuracy and surface roughness, while temperature is the most important factor.

Most universities have included computer-aided design (CAD) pattern making systems education and training in their clothing technology courses in recent years, so as to respond to the actual needs of the fashion world for high-skilled fashion designers and clothing engineers. With the rapid rise in the use of open source software (OSS) in all types of applications, it is important to know if the existing OSS CAD software for garment prototyping development can successfully support the learning process. The present study compares two commercial licensed CAD systems for pattern design (Polypattern and Create) to an open source software, Seamly2D, and to Wild Ginger’s Caveo V6 programme, which runs within an OSS. In total, two licensed and two OSS systems have been evaluated in their weights in accomplishing the garment development of ten different pattern designs. The results obtained for the evaluation of a set of OS and licensed CAD systems are presented and critically discussed.

Nature is a great laboratory where many experiments are taking place every moment. Especially, nature-based design is perhaps the oldest methodology of design with examples from all over the fields of applied sciences. From the conceptual side, product design uses a different approach in nature-based methodology. The proposed conceptual product design concept is dealing with in-store displays that are inspired from nature forms. Those nature-based design ideas can lead to further opportunities for research and marketing success of the retail industry. A number of illustrative case studies of in-store displays are presented in this paper.
