In this study, a new method for identifying the key indicators and dependencies in processing images of helical surfaces of conical cutters at the main stages of the production cycle, which is based on the relationships between the shape of the cutting edges, the angle of inclination of the helical flute, clearance angle, color intensity and image brightness, has been developed. Design and geometric parameters were exported from the simulations with the model created by the automated system for designing conical cutters, which determines the dimensions, shape and geometric parameters of the cutting part of the tool. The identified dependencies allow determining the active zone and the transfer coefficient at the interface between the rear surface and the measuring machine and a stable connection is carried out with a group of cutting part parameters obtained from the results of the CAD system. A high-resolution image of the flank surface boundary zone is scanned with an optical camera on a specialized machine, and the improved method was used to quantitatively calculate the boundary The controlled measurements of a set of point coordinates and geometric parameters of the helical surface of a conical cutter forms a system for a comprehensively studying the designs of conical cutters and the physical mechanisms of their production using image analysis based on the developed indicator interpretation system, which is a foundation for a unified digital cyber-physical production system to be developed. The combination of improved performance or expanded functional capabilities with increased rigidity and reliability, which enables the processing of a wider range of structural designs of part surfaces, is the primary competitive advantage of the new generation of cutting tools with unique working surface geometries. These tools are designed and manufactured using a developed cyberphysical system from contemporary tool materials. With the least amount of frames, the new method's application enables the quickest possible identification of findings that are appropriate for monitoring the back surface of the cutting tool class under consideration.

Helical surfaces are important elements of solid end mills. Their production is carried out using multi-coordinate grinding. Shape errors and reduction in the quality of the screw surface appear due to abrasion, high pressure, and wear of the grinding wheel. Therefore, it is extremely important to measure geometric accuracy, to perform linear and angular measurements, and to study the properties of rake helical surfaces. The paper proposes improvements to monitoring of helical surfaces via the use of a new computer vision system for assessing microtexture on helical surfaces after multiaxis grinding on CNC machines. A computer vision system was developed to evaluate defects on helical surfaces after multi-coordinate grinding on CNC machines, and a comprehensive analysis of existing indicators for recognizing the defect was carried out in a guaranteed range of probability of finding a solution of 99.7% for the distribution density of grinds. To verify the developed method, the accuracy of surfaces obtained by using the one was compared with the measurements carried out using specialized equipment for the control of the accuracy of helical surfaces. A new system for monitoring the accuracy and defects of cutting edges, helical front and rear surfaces allows establishing the main geometric parameters of the cutting edges and cutting wedge such as flute angle and rake angle at the apex using key indicators of the difference in color intensity in the focal zone of the image. When developing this approach, it was found that areas with smaller curvature of the rake surface are more susceptible to the accumulation of helical flute pitch errors after grinding. Experimental studies of the system operation were conducted to provide empirical evidence on helical surfaces after multiaxis grinding on CNC machines, demonstrating excellent convergence and defect recognition accuracy. The accuracy of determining the results of the inclination angles of the microtexture surface after grinding at the control point is 2-2.5 degrees, which allows you to form a comprehensive solution for scanning the surface, which will allow you to apply a simple method of control using a camera in reflected light.

In precision engineering, helical surfaces on critical parts of equipment have become widespread. The article proposes an new method and practical recommendations for measuring geometric accuracy, linear and angular measurements, and studying the characteristics of helical surfaces and specialized equipment for monitoring the accuracy of helical surfaces. The uniqueness of the approach lies in the formation of key indicators of classification and filtering of a set of specialized measurement techniques based on scanning and digital image processing. A new method is proposed that makes it possible to adjust the measurement of the coordinates of the profile points of the helical surface in the radial section according to the shape of the focal area on the helical surface obtained by a reflected light camera. The work established new indicators of the effectiveness of tool control for high-speed multi-axis milling based on recommendations for the selection of methods and means of monitoring and control at the stage of technological preparation of production in real time. Criteria and indicators have been formed to eliminate errors at any stage in the process of digital control of images of the helical surface of a cutting tool for high-speed machining. The method consists in determining the law of preserving the shape of the profile, its further rotation and comparison with the original control profile by identifying a new relationship between the focal length and the profiling shape. The shape of the profiling curve is described depending on the angle of inclination of the helical flute, diameter, segmentation of the image in the focal zone and the magnitude of the error when measuring the profile in real time relative to the base profile. In this regard, the work justifies the practical adaptation of the search results for key measurement schemes in comparison with other existing methods for helical surfaces with an rake angle of the tangent to the profile in the axial section. The new level of production creates greater demand for product quality efficiency in a unified digital environment. As an advanced solution, the work proposes a method for compensating for errors in the shape of the focus area. This method allows you to compensate for the error in real time without stopping for readjustment. More accurate results allowed for an increase in accuracy up to 10 times compared to existing methods.
