In order to increase the machining accuracy of slow tool servo turning of complex optical surface, the optimal design for tool path was studied. A comprehensive tool path generation strategy was proposed to optimize the tool path for machining complex surfaces. A new algorithm was designed for tool nose radius compensation which had less calculation error. Hermite segment interpolation was analyzed based on integrated multi-axes controller, and a new interpolation method referred to as triangle rotary method was put forward and was compared with the area method and three-point method. The machining simulation indicated that the triangle rotary method was significant in error reduction. The interpolation error of toric surface was reduced to 0.0015 µm from 0.06 µm and sinusoidal array surface’s interpolation error decreases to 0.37 µm from 1.5 µm. Finally, a toric surface was machined using optimum tool path generation method to evaluate the proposed tool path generation method.

The purpose of electrical load management in a manufacturing plant is to change the load profile in order to gain from reduced total system peak load and increased power factor. One of the widely taken approaches is to optimize the schedule of electrical equipment operation hours to take advantage of incentives and favorable pricing offered by utilities. In this paper, we present our work in designing and developing a web based tool for manufacturing plants to find out an optimal operation schedule of equipment so as to reduce energy cost. The tool allows users to configure their load by specifying electrical devices and their various parameters. Then the online system will assess power consumption over a certain time period, as well as peak power demand and power factor of the defined load.

Chemical compatibility of self-lubricating ceramic tool materials, such as Al2O3/TiC/MoS2, Al2O3/TiC/h-BN, Al2O3/TiC/CaF2, were analyzed and calculated, and the results were verified by X-ray diffraction patterns. The optimal volume content of solid lubricant was calculated by the thermal stress theory under specific condition. The results show that under high temperature, there were some reactions in Al2O3/TiC/MoS2 and Al2O3/TiC/h-BN, while there were no reactions in Al2O3/TiC/CaF2. To Al2O3/TiC/CaF2, the optimal volume content of CaF2 is 25.1% under specific condition.

The scope of this work is to introduce a software tool for optimization of circular spiral inductors. It is based on compact model, where the physical behavior is described through analytical expressions in geometric programming (GP) form. This paper describes three significant innovations (a) optimization of circular inductor via GP, (b) new expressions for inductance and Q-factor in GP form, (c) globally optimal trade-off curves between maximum self-resonant frequency and inductance values or minimum inductor area and inductance values. The proposed optimization algorithm is flexible because the designers of RF integrated circuits can easily optimize the circular inductor for a desired performance.

Purpose The purpose of this study was to compare machining performance between chemical vapor deposition (CVD)- and physical vapor deposition (PVD)-coated cutting tools to obtain the optimal cutting parameters based on different types of tools for machining titanium alloy (Ti-6Al-4V). Design/methodology/approach The design of the experiment was constructed using the response surface methodology (RSM) with the Box–Behnken method. Two types of round-shaped tungsten carbide inserts were used in this experiment, namely, PVD TiAlN/AlCrN insert tool and CVD TiCN/Al2O3 insert tool. The titanium alloy (Ti-6Al-4V) material was used throughout this experiment. The tool wear and microstructure analysis were measured using a tool maker microscope, an optical microscope and a scanning electron machine. Findings The PVD TiAlN/AlCrN insert tool produces the lowest tool wear that significantly prolongs the cutting tool life compared to the CVD TiCN/Al2O3 insert tool. In addition, depth of cut was the main factor affecting the tool life, followed by cutting speed and feed rate. Originality/value This study was conducted to compare machining performance between CVD- and PVD-coated cutting tools to obtain the optimal cutting parameters based on different types of tools for machining titanium alloy (Ti-6Al-4V). In addition, the information presented in this paper helps reduce the manufacturing cost and setup time for machining titanium alloy. Finally, tool wear comparison between PVD- and CVD-coated titanium alloys was also presented for future improvement for tool manufacturing application.

Shape optimal design methodology has been used as a design tool in the automotive and aerospace industries for quite some time now. In the present work the hybrid natural shape optimal design approach is used along with a nonlinear programming (NLP) technique to find the optimal shapes of electronic packaging components. The design problems are formulated as min-max problems and linear and materially nonlinear finite element analyses provide the function values. The applicability of the developed methodology is illustrated using a design example that deals with the packaging design of a plastic pad array carrier digital package. The results indicate that the methodology can be used either as an effective way of evaluating different design alternatives or refining existing designs.

Due to commercial restrictions, aiming for greater product competitiveness, uninterruptible power supplies (UPS) must exhibit optimal design in order to reduce losses, volume, and noise, as well as increase power density. However, the optimal design of a power electronic converter is a complex and repetitive task, often requiring the use of a computational tool. The main objective of this work is to present a unified computational tool capable of helping the designer to find the optimal design for a given power electronic converter. This paper will show a comparison between two power converter design techniques: the traditional industrial design approach and a multi-objective optimization approach using Pareto analysis. For this purpose, the total performance of a 10 kVA UPS was compared in terms of losses and volumes. The use of the proposed computational tool to optimize the design resulted in a UPS with better power density and efficiency.

With the advent of computers and search and optimization tools such as the genetic algorithm, the ability to manipulate numerous aircraft design parameters in a reasonable amount of time is feasible. From this angle, the lengthy time and effort spent creating and integrating aerodynamics codes, sizing routines, and performance modules, can be mitigated by the use of a genetic algorithm. Consequently, a genetic algorithm has been created and employed as a cost effective tool to explore possible aircraft geometries in the conceptual design process of the aircraft. A program has been developed to address most aspects of aircraft design such as aircraft sizing and configuration, performance, and propulsion, to name a few. These codes have been integrated into a genetic algorithm, which performs the task of searching and optimizing. The adaptive penalty method has been employed to handle all constraints imposed on the design. In addition, adjustments for varying degrees of selection and crossover intensities and types have been studied. A design study has also been carried out to compare an existing aircraft shape with the genetic algorithm optimized aircraft shape and configuration. Results indicate that the genetic algorithm is a powerful multi-disciplinary optimization and search tool, capable of simultaneously managing and varying numerous aircraft design parameters. Moreover, the genetic algorithm is capable of finding aircraft geometries and configurations that are both efficient and cost effective.

Products are becoming increasingly complex; therefore, designers are faced with a challenging task to incorporate new functionality, higher performance, and optimal shape design. Traditional user-centered design techniques such as designing with anthropometric data do not incorporate enough subject data to design products with optimal shape for best fit to the target population. To overcome these limitations, we present an interdisciplinary approach with medical imaging. The use of this approach is being presented on the development of an optimal sized and shaped tool handle where the hand is imaged using magnetic resonance imaging machine. The obtained images of the hand are reconstructed and imported into computer-aided design software, where optimal shape of the handle is obtained with Boolean operations. Methods can be used to develop fully customized products with optimal shape to provide best fit to the target population. This increases subjective comfort rating, performance and can prevent acute and cumulative trauma disorders. Provided methods are especially suited for products where high stresses and exceptional performance is expected (high performance tools, professional sports, and military equipment, etc.). With the use of these interdisciplinary methods, the value of the product is increased, which also increases the competitiveness of the product on the market.

Presented in this paper is a feature-based method for selecting an optimal (minimum yet sufficient) set of modules necessary to form a reconfigurable machine tool for producing a part family. This method consists of two parts. In the first part, a feature-module database is created to form a selection space, where the machinable geometric features identified in STEP are defined as functional requirements (FR’s) and the structural component modules derived from the conventional machine tools as design parameters (DP’s). An inner FR-to-DP mapping mechanism within the database is based on the “Membership Grade Matrix,” which defines metrics to quantify the degree of association between a FR and a DP. Within the confines of the selection space built upon this FR-DP database, the second part of the method involves a two-step procedure for module selection. The first step is to select the modules from this space to construct all the required individual configurations of the reconfigurable machine tool. The second step is to maximize the number of common modules among the originally selected modules through re-selection. A case study on designing a reconfigurable machine tool dedicated to a given family of die molds is conducted and discussed.

Ultrasonic vibration system is the chief component of USM machine tool. Whether products are precisely machined is lie on the performance of the system. To design good performance of ultrasonic vibration system, finite element method is used to analyse the dynamic performance of the system based on theoretic calculation. The dynamic performance of transformer and transformer with tool is analysed respectively, including natural vibration characteristic and harmonic characteristic. The result of FEA is compared with theoretic calculation. The parametric optimization design technique of the finite element analysis package ANSYS is applied to optimize the structure dimension of the piezoelectric transducer and transformer with tool. Then amplitude of the optimized system and the previous system is compared based on laser-CCD sensor for micro-displacement. The optimized system is more superior and has larger amplitude. Last some round holes are machined on kentanium YG8, monocrystalline silicon, PZT. And machining effect of single Micro-USM is got by the test.

The acoustic telemetry used the drill string as a communication channel, which allows data transfer without interrupting drilling operations. This technology suffers from stop-bands that reduce the feasible bands for transmission up to 60 percent. The stop bands come due to the structure of the drill string constructed from pipes and tool joints. In this paper, we optimized the design of the drill string main components, which are pipes and tool-joints lengths, with an aim to increase the pass-bands total bandwidth. Using the verified drill string channel model, we proved that, with optimal lengths of pipes and tool joints, we can make the whole drill string channel bandwidth available for transmission. We also investigated the effect of small deviation from the optimal lengths on the channel transmission bands. The results showed that an increase of more than 138 percent in the available transmission bandwidths compared with standard drill string dimensions.

Abstract We propose a model that aims to fulfill the following three necessities: the demand for refurbishing the existing built environment, the lack of a reliable means to help architects navigate among the numerous possible solutions for low-energy constructions, and the need for a multi-function tool to analyze buildings as complex systems. We introduce the Optimal Refurbishment Design (ORD) model that is a novel tool to help architects with the refurbishment of an existing building or the design of a new one. The ORD shows four innovative aspects. First, it opens the way to passive building design while focusing on affordable solutions. Second, its core component is based on mathematical optimization. Third, it simultaneously outputs optimal thermal mass and insulation of all the required elements in the building. Fourth, it automatically accounts for the user’s needs and local regulations. Unlike most of the approaches in the Literature, the ORD’s outputs are not limited by any pre-defined set of materials or strategies. We tested the ORD using a realistic study case of refurbishment, and found that the renovated house achieved the energy consumption of a Passive House by lowering its annual heating/cooling consumption by 23% with a payback period of less than 5 years.

There are still some product design and development processes in the metal-mechanics industry that continue to be based principally on similar experiences and on the designer's own experience. These designs are, in later phases, generally checked and analysed by means of FEM (Finite Element Method) simulations or other methods in order to verify whether they are optimal. The creation of tools with which to assist design in the initial phase is, therefore, a major step forward as regards facilitating the attainment of good results in the shortest possible time and with the least possible number of design-simulation-redesign iterations. The objective of this paper is to provide a detailed description of a methodology based on mathematical formulation for the creation of tools to assist in the design of moulds or dies in the metal-mechanical sector. The strategy is based on the value analysis of a multitude of variables from a large number of proven optimal designs. The result is an assistancea tool that, by means of a mathematical formulation, attempts to concentrate the experience and know-how accumulated in many previous designs. This tool can be quickly and easily applied in order to check and attempt to adjust a new first design to the criteria of the accumulated experience. An example of the application of the methodology by means of an assistance tool with which to design aluminium extrusion porthole dies is, therefore, shown. Several lines of research, however, remain open as regards other applications of the methodology and its improvement through the introduction of artificial intelligence.

The functionality of compound multiaxis machine tools is becoming increasingly versatile as NC lathes evolve. A single compound multiaxis machine tool functions as a 2-axis NC lathe and as a 5 axis machining center. The compound multiaxis machine tool executes machining such as inclined surface and gear cutting, conventionally executed by dedicated machines with special jigs and fixtures. A survey has shown that most machining executed by conventional compound multiaxis machine tools consists of basic drilling and milling on the orthogonal plane, indicating that compound multiaxis machine tools specifications should be designed to meet these requirements. To improve competitiveness and return investment over conventional NC lathes and machining centers, productivity required for a compound multiaxis machine tool is derived based on the machining time of typical parts on conventional machines. Here, we address systematic analysis and methodology to determine compound multiaxis machine tool specifications from the viewpoints of quality and cost.

A calculation scheme to gain the relationship between the thickness of shrink-fit holder and thermodynamic properties. Based on the theoretical analysis of fitting molder between shrink-fit holder and tool, then the thermodynamic properties of the shrink-fit holder and cutting tool such as contact pressure, equivalent stress and deformation are analyzed at different thickness of shrink-fit holder in static, under cutting force and inducting heating by using the finite element software ANSYS. The results show that the total contact pressure and maximum equivalent stress increased and the minimum thermal displacement difference decreased with the increase of holder thickness. Under the action of cutting force, the contact stress on the tool holder no longer uniformed and the maximum contact stress significantly increased, cutting tool also deformed. Finally a method to determine the reasonable holder thickness is given and it has a practical guiding significance for the design and selection of the shrink-fit tool holder.

An experimental computer system for globally optimal design, called BAGOP, is discussed. This new tool uses the computer algebra system MACSYMA to implement a variety of tests and branching rules in a flexible branch-and-bound framework. Many problems of globally optimal design have been solved by BAGOP, some of them for the first time, and most of them for the first time in an entirely automated way.

Abstract. A recent trend in automotive industry is adding electrical drive systems to conventional drives. The electrification allows an expansion of energy sources and provides great opportunities for environmental friendly mobility. The electrical powertrain and its components can also cause disturbances which couple into nearby electronic control units and communication cables. Therefore the communication can be degraded or even permanently disrupted. To minimize these interferences, different approaches are possible. One possibility is to use EMC filters. However, the diversity of filters is very large and the determination of an appropriate filter for each application is time-consuming. Therefore, the filter design is determined by using a simulation tool including an effective optimization algorithm. This method leads to improvements in terms of weight, volume and cost.

Ultrasonic cutting technique is an advanced processing method of cutting honeycomb materials. An ultrasonic pointed cutter was designed. Combined with the principle of ultrasonic cutting, the mathematical model of the tool was established. Modal analysis of the tool was calculated with the finite element software to study the effects of tool geometry on the natural frequency. The results show that the natural frequency increases as the tool thickness increases, but it decreases as the tool length increases. And it obtained the modal shapes and natural frequencies of the tool which meet design requirements. The optimal geometry of the tool was also determined. Finally, it verified the rationality of tool design by amplitude measurement experiment of the tool.

Purpose: Recently, comprehensive open-source software (OSS) solutions for medical images have been developed. They offer powerful tools for the management, visualization, storage and analysis of images. The purpose of the present study was to present the features and use of OSS in comparison with commercial software solutions when evaluating medical images. Methods: A case study of the development of a tool handle of optimal size and shape using the free OSS “3D Slicer” is presented. Many authors recommend cylindrical-shaped handles to increase comfort, performance and to avoid cumulative trauma, but none have considered the optimal shape of the handle. Hence, we derived a method for obtainingan optimally shaped tool handle based on the power grip hand posture and non-deformed soft tissue. During magnetic resonance imaging (MRI), an outer hand mold was used to maintain the optimal hand posture. 3D Slicer was used for segmentation and 3D reconstruction of MRI. A three-dimensional (3D) hand model was exported to a commercial program for computer-aided design for the optimal tool handle. Results: Measurements of the diameters on 3D reconstruction showed that the position of fingers wasere withheld within small deviations, which maximized maximum finger force exertion. An optimally shaped handle this way provided 25% higher contact area compared with the optimal cylindrical handle. It therefore reduced contact pressure, increased performance and comfort and could probably prevent disorders due to cumulative trauma. Conclusion: This case study supported the use of OSS for medical imaging as a powerful and (mostly) free tool comparable with (usually expensive) commercial solutions.

Compound multiaxis machine tools are used to machine high-value-added parts through integrating milling and turning. Compound machine tools are generally structured based on a conventional NC lathe by incorporating Y axis and automatic tool changer (ATC) components for milling. Due to complexity of the structure and functional versatility required for a compound machine tool, accuracy, productivity, and return on investment (ROI) must be improved over conventional NC lathes and machining centers. In the sections that follow, we discuss design methodology for compound multiaxis machine tools, focusing on the design of an optimal basic structure for high accuracy and high productivity. We propose a box in box structure, a movable column-Y axis, and a boring machine structure. We analyzed static rigidity, dynamic features, and movement accuracy of machine structures theoretically using FEM for three proposed structures. We found that the box in box structure is suitable for compound multiaxis machine tools to achieve high accuracy and high productivity.
