In this paper, a Drill Point Simulation System (DPSS) which is being developed at Northeastern University is presented. By means of DPSS, the geometric models of the helical drill points were shown after inputting their design parameters. Then, the grinding parameters of the helical drill points were produced. According to the grinding parameters, the helical drill points were ground by the SD helical drill point grinder which was developed at Northeastern University. Furthermore, drilling tests were performed on aluminum sheet workpieces to investigate drilling performance of the helical drill points. In addition, the relationships between the geometric parameters of helical drill points and their grinding parameters also were derived.

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.

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.

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.

In the high-speed page printing systems used as peripherals to computers, the paper moves at a speed of around 30 in./s. The printing and punching of the paper has to be done when the paper is in motion. If the punching is not finished in a short enough time, the paper would get torn up by the punchette. In a typical punch assembly as used in modern page printing systems, a plunger is driven forward by the force of a solenoid. Plunger impacts the punchette which in turn punches a hole in the paper which is in motion. To minimize the flight time of the punchette with the object of increasing paper speed, the design parameters of the punch assembly must be carefully selected. In this paper, a model for the punch assembly is developed. The necessary equations for plunger and punchette motion are derived. The design parameters, such as the masses of the plunger and punchette, constants for springs used in the assembly, force generated by the solenoid, and the gap between the plunger and punchette, are varied using a Rosenbrock algorithm to minimize the flight time of the punchette. The results obtained indicate that by the use of a Computer-Aided Design approach optimal values of design parameters can be found before the development of prototypes and experiments.
