In this paper, the mechanism of a slotting spindle head for the implementation of rectilinear motion based on a rack and pinion is considered. A three-dimensional modeling procedure of the slotting head elements for a multioperational machine tool of the drilling-milling-boring type has been carried out. 3D models of the rack and pinion were built in the integrated CAD KOMPAS using its built-in geometric core. An assessment of the stress-strain state in the engagement zone is given using the finite element method. The concept of increasing the load capacity due to the proposed version of the teeth envelope surface with curved axoids is analyzed. An analytical apparatus for determining the basic design parameters of a rack and pinion transmission modified version is proposed. The calculation of the geometric parameters for the end profile of the gearing teeth is experimentally realized, taking into account the found value of the disk milling cutter diameter for teeth cutting by the copying method.

“…When machining parallel spline shafts, their profile is formed as a result of generating around the spline by the cutting edges of the tool when rolling without sliding the centroid (initial straight line) of the workpiece (Fig. 2.3) [39,40]. During the generation motion of the centroid, the provisions of the theory of conjugate profiles must be fulfilled:…”

“…The final value of the size of the mounting bore diameter of the cutter is taken as one of the largest nearest numerical values of the normal range of sizes of mounting bore diameters of the arbor-type cutting tool: 19,22,27,32,40,50, determined by GOST 9472-70. After establishing the dimensions of the keyway t k and b k following GOST 8788-58 for the selected hole diameter, it is necessary to check the following condition: 3.…”

The monograph deals with the design, calculation and modelling of gear cutting tools. Calculation forms are proposed for the creation of tools structures working by the methods of form-generating and form-copying. Three-dimensional and parametric models of worm wheel hob and worm spline cutters, shaper-type cutters and interlocking disk milling cutters in the environment of integrated CAD KOMPAS-3D and APM WinMachine using specialized applications "CAD Mills" have been built. Calculation forms for determining the geometric, kinematic and design parameters of worm wheel hob for the manufacture of spur and helical gears based on the original contour profile of a standardized gear rack are given. An interactive design of a worm wheel hob in the KOMPAS system was carried out. The design stage of determining the characteristics of the flank-shaped tooth profile modification to reduce the noise level and increase the service life of the gear transmission has been effectively implemented. An interactive procedure for designing a worm spline cutter in the KOMPAS environment for finishing spline shafts is proposed. At the stage of replacing the theoretical profile of the cutter tooth edge with an arc of one circle or tangent arcs of two circles, an express procedure for calculating the magnitude of the error is used. Computer design and research of the shaper-type cutter using the application program "Shaper cutter" in the KOMPAS-3D environment was performed. It is shown that for non-standard shaper-type cutters it is possible to use a standard helical copier of a gear shaping machine if the angle of teeth inclination is 15 0 ±0.5 0 or 23 0 ±0.5 0 . A comprehensive study of interlocking disk milling cutters using the application program "Disk milling cutter" in the CAD KOMPAS contour was carried out. Parametric models of the disc cutter design are built using the syntax of the CAD APM WinMachine. The parametric models of a single-and double-relief tooth, as well as the involute profile of the tooth lateral surface, have been identified.

“…The proposed criterion allows evaluating the technical level of hydraulic devices, depending on their design and operational parameters. It can be done at the CAD (Computer-aided design) stage [46]- [49]. This criterion is based on common methodological principles based on the data given in the relevant directories or technical specifications for the design of the product.…”

A basic purpose of a good healing patch is to reduce the reproduction of bacteria in the wounded area with minimal effect of mechanical properties. This study focuses on the basic mechanical and biomechanical properties of the material for a healing patch application with a new composition of biodegradable ingredients by using the estimation of hyperelastic models to fit with the experimental data and the comparison between the commercial Aloe vera gels and original Aloe vera leaves. This project was started with a material selection which is gelatine and Aloe vera leaves as the main ingredient. Secondly, the specimen sets undergo a uniaxial tensile test to obtain the raw data. For numerical phases, the conventional theory of large deformation based on hyperelastic constitutive equations and Stress-Strain Energy Theory were identified. The final step for this project is curve fitting between experimental data (Ogden and Mooney-Rivlin hyperelastic models). New parameters were carried out for healing patch materials made of hybrid biomaterials from the hyperelastic theory. The Ogden and Mooney Rivlin trends were closely followed by the curve fit presented with a minor difference. Overall, the original Aloe vera leaves' values were Ogden (α=1.8792, µ=0.1881 Mpa) and Mooney-Rivlin (C1=0.0713, C2=0.0304) respectively. The significance of this project is to expand the knowledge about mechanical properties of natural polymers for wound healing application instead of depending on semi-synthetic polymers.
