New Experimental Expression of Durability Dependence for Ceramic Cutting Tool

Abstract

Durability of the cutting tools is very complex process that is influenced by more factors. To the Identify these factors is necessary execute many experiments. The technical science defines the basic method for determining durability of the cutting tool according to results and knowledge F. W. Taylor. The Literature from renowned authors indicates that durability of the cutting tool is defined on the base of T-vc dependence. T-vc dependence like a elementary durability dependence was described according to Taylor´s graphics dependence VB=f(s) for different cutting speeds in 1906. From this theory were later derived others theories, that became the basis of theories durability of cutting wedge for the different cutting materials. For the durability identification of the cutting tool are in technical practice used two basic tests. The First is the short-term durability test and second is machining long-term test method. Both these tests have some advantages and some disadvantages that are described in Introduction of this paper. This paper describes how to create and analytically express new durability dependence for ceramic cutting tool on the base of vc-VB dependence. This dependence consists from vc - cutting speed and VB - criterion of blunting. The whole procedure and its analytical expression is the subject of this paper.

Implementation of Integrated Management System in Order to Enhance Equipment Efficiency

“…Todic et al [20], Durdan et al [4] and Krenicky [11] implemented multifactorial monitoring methods for evaluation of complex variation of characteristics. Cacko & Krenicky [2], Panda et al [15,16], Olejarova et al [14] and Prislupcak et al [17] provided analysis of exposed parts technical characteristics in order to determine the operating status and durability, Jurko et al [10], Monkova & Monka [13] and Valicek et al [21] developed methods and gave examples of the evaluation of particular properties.…”

“…An even more difficult situation is when a single system of standards is already implemented in the organization and is functioning successfully and the moment when the consumer demands from his supplier the introduction of a quality management system according to the industry standard (for example, ISO/TS 22163:2017 [9]). Thus, there is a contradiction between the need for the development of integrated models that allow for the analysis of dynamic evolutionary processes occurring at the interval of the product lifecycle management (PLM) [1,16,18] of sophisticated products, and the insufficiency of the existing regulatory and methodological support for the synthesis of such models in order to manage these processes. The solution to this problem is proposed to be sought in the creation and use of logical system-wide evolutionary models that must take into account the dynamic, parametric, economic, energy and operational processes occurring in each particular complex technical system [5,10,12].…”

Criteria for the Optimization of Production Processes in Machining of Metallic Materials

“…Economics and optimization of the production, new modern industrial machinery equipment, new manufacturing fixtures and new technologies have nowadays increasingly wider application in the manufacturing and industry [19,20]. All the relatively new technologies appeared in the second half of 20. century, however, new technologies appear every day.…”

Properties Prediction of Linear Block-Polyurethanes Based on the Mixtures of Simple Oligoethers

“…Jurko et al [6,7,8] studied mechanical deformation of materials during processing and operation, Valicek et al [21] developed method of the deformation evaluation. Cacko & Krenicky [4] and Panda et al [13,14,15,17] analyzed thermal and tribotechnical characteristics of mechanically exposed parts in order to determine their operating status and durability.…”

“…In addition, block-polyurethanes based on oligoethers have increased hydrolytic resistance, frost resistance, more resistant to microorganisms, and therefore are of particular interest. Therefore, the relationship study of linear block-polyurethanes (BPU) based on mixtures of oligoethers structure with strength, deformation, rheological and tribotechnical characteristics, mathematical prediction of their behavior in different operating conditions, taking into account the quality indicators of the material, is of great practical importance for use in industry [3,4,14,16]. It was found that main characteristics that determine the properties of linear block-polyurethanes are their molecular weight and the concentration of rigid segments in a macromolecule [11,13,19,20].…”
