Article
Brittle materials such as ceramics, glass or single-crystal silicon are extensively used for industrial applications and recently become an object of actual research due to the development of new products and technologies. In cases, where special attention is paid to the surface layer, mechanical processing with a diamond tool is of interest as one...
Article
Parts made of modern brittle materials with high quality finish are widely used in manufacturing of optical and electronic devices as well as crucial assemblies in mechanical engineering products. Diamond machining enables generation of geometry without affecting the functional surface layers by heat. At the same time, brittle material cutting is a...
Chapter
This paper discusses the predictive modeling of a scribing process. The diamond tool geometry is important for this process. As a prototype for the diamond tool, a four-sided pyramid is taken. Some minor changes are made in its geometry in purpose to make the modified tools. The tool geometry is a factor which affects greatly the quality of a final...
Conference Paper
Crucial economy in work-time and human operators’ workload can be achieved by using a fully autonomous robotic complex for power lines diagnostics. In this paper, the mobile robotic complex is presented that consists of a quadrotor unmanned aerial vehicle with rotary wings, wheeled platform and onboard diagnostic devices. The design of the platform...
Conference Paper

This paper is focused on 3D computer simulation of cutting processes for brittle materials and silicon wafers. Computer-aided analysis of wafer scribing and dicing is carried out with the use of the ANSYS CAE (computer-aided engineering) software, and a parametric model of the processes is created by means of the internal ANSYS APDL programming lan...
Conference Paper
This paper presents finite-element simulation of scratching on a brittle plate with functional coating under force loading by a diamond tool. To calculate stresses inside the plate and under the tool tip, a numerical experiment is set up and a parametric task is formulated. The task is solved with use of the ANSYS Programming Dynamic Language. The...
Article
The geometry of a diamond cutter based on a tetrahedral pyramid for splitting sheet blanks is analyzed. An algorithm for cutter design is formulated.
Article
Full-text available
The paper presents the results of computer simulation of silicon wafers under scribe loading conditions. Finite Element (FE) analysis was applied to estimate a value of stresses and spread of defect zone around scratch line. It was revealed that due to impact of diamond tip, a complex stress-strain state is produced in the wafer, which is related t...
