This paper presents the design strategy for the Computer-Aided Design (CAD) of compact helical gear sets. Using optimization techniques, fundamental gear design parameters such as the number of teeth on the pinion, helix angle, and diametral pitch (or module) are selected subject to constraints on bending stresses, contact stresses, and involute interference limits for both standard and nonstandard gearing. The CAD procedure is illustrated with the help of a design example.

Drill Design

In Part II, a computer program that aids in the design of a twist drill is described, based on the analysis presented in Part I. A true drill and a “computer-designed” drill having identical design and grinding parameters are compared in orthogonal cutting planes. The effects of the design parameters on drill geometry are investigated utilizing the computer program.

The article is to study the development of computer-aided design of X-ray microtomography - the device for investigating the structure and construction three-dimensional images of organic and inorganic objects on the basis of shadow projections. This article provides basic information regarding CAD of X-ray microtomography and a scheme consisting of three levels. The article also shows basic relations of X-ray computed tomography, the generalized scheme of a X-ray microtomographic scanner. The methods of X-ray imaging of the spatial microstructure and morphometry of materials are described. The main characteristics of an X-ray microtomographic scanner, the X-ray source, X-ray optical elements and mechanical components of the positioning system are shown. The block scheme and software functional scheme for intelligent neural network system of analysis of the internal microstructure of objects are presented. The method of choice of design parameters of CADof X-raymicrotomography is aimed at improving the quality of design and reduce of costs of it. It is supposed to reduce the design time and eliminate the growing number of engineers involved in development and construction of X-ray microtomographic scanners.

The use of Topology Optimization techniques has seen a great development since the last decade. The principal contributor to this trend is the widespread use of Additive Manufacturing technologies to effectively build complex and performant structures over different settings. Nevertheless, the use of Topology Optimization in Design for Additive Manufacturing processes is not simple and research aims to fill the gap between theory and practice by evolving at the same time both approaches, workflows, and design software that allow their implementation. Since a strong connection between methodologies and tools exists, this work proposes a method to assess computer-aided design tools or platforms. This can be applied to sustain the key phase for selection and adoption of the computer-aided tools in industrial settings embracing Additive Manufacturing. The workflow for Topology Optimization implementation, the structure of the proposed evaluation approach, and its application, are presented to demonstrate effective usability. The automotive case study is the redesign of internal combustion engine piston to benefit of metal Additive Manufacturing based enhanced product performance. A preliminary finite element model is defined and a Topology Optimization based redesign is concurrently set up through four different commercial computer-based platforms. The method accounting for the assessment of required operations for the design optimization is applied to perform the tools selection phase.

This article provides a mathematical framework based on the basic law of gear kinematics for calculating the tooth geometry of arbitrary gear types. The described algorithms are illustrated by means of practical applications, especially nonstandard gearings. The computed geometry is exported as a point cloud with integrated STEP-modeling. Thus, further analysis of the generated gear types are possible, e.g. by computer-aided design or finite-element software tools as well as manufacturing on 5-axis-CNC or forging machines.

JSC Almaz-Antey in the implementation of the integrated design of complex electronic systems, particularly radar systems, it is required to solve the problem of choosing and optimizing the design parameters of radar devices, including antenna systems, transmitter-receiver paths of radar systems (radar), algorithms and devices for digital generation and processing of radar signals, and radar systems in General. Currently there is no domestic computer-aided design systems that solve these tasks in the complex. Therefore, to solve such problems, the Concern’s enterprises are used by a number of disparate software solutions with their own development and their foreign counterparts. Due to the restrictions caused by the sanctions, the closed scope of the work, as well as in import substitution, highly relevant is the creation of CAD radar, allowing to solve the above problems in a continuous end-to-end loop design. The development of CAD radar conducted by the JSC Almaz-Antey, its subsidiaries and companies with expertise in the design of the radar, using their existing backlog. The paper shows the General architecture of a domestic computer aided design in full cycle end-to-end radar systems (facilities, stations); the concept of five levels of design in the system being developed and the basic requirements for the implementation of this concept. The specificity of the developed computer-aided design system is most pronounced in activity-based scenarios for the use of the designed product in terms of specific air and space attack and defense, and is implemented in the form of functional simulation of the fighting.
