INTRODUCTION OF A COORDINATE MEASURING MACHINE AFTER A RESPONSIBLE OPERATION USING THE MES SYSTEM AS A WAY TO MINIMIZE THE NUMBER OF DEFECTIVE PARTS IN THE MANUFACTURE OF PRODUCTS

Posted in 2021, ENGINEERING, Issue №9 (111) September 2021 | 0 comments

The article states that at the moment, the use of a coordinate measuring machine (CMM) after a responsible operation of the technological process is relevant. MES systems are used to solve the problems of creating a production schedule and optimal equipment loading. They solve such tasks as increasing the reliability of the execution of specified production order deadlines, increasing the speed of order execution and the efficiency of equipment use. The article examines the option of implementing CMM after a responsible operation of manufacturing a product in order to promptly detect inconsistencies in the geometric parameters of the product with the requirements of regulatory documentation. A graph is constructed that visualizes the time spent on manufacturing a part during the introduction of CMM and without it, both in case of detection and in case of non-detection of defective products. According to the results of analyzing the graph, it is formulated that the introduction of CMM after a responsible operation into the technological process together with the use of the MES system will minimize the number of defective parts at the output and reduce the time spent on their manufacture. In order to visualize the sequence of operations of the technological process of manufacturing a product when implementing CMM after a responsible operation, this technological process is presented in the form of IDEF3 notation. It is indicated that the introduction of CMM after a responsible operation into the technological process is relevant in the aspect of the development of Industry 4.0 tools.

METHODS OF PROTECTION AGAINST CAVITATION EROSION

Posted in 2021, ENGINEERING, Issue №9 (111) September 2021 | 0 comments

Ensuring cavitation safety remains a relevant task in relation to hydraulic structures. In practice, it is known that many hydraulic structures during operation fail before the deadline due to insufficient resistance of concrete and reinforced concrete structures to aggressive environments. Methods of protecting hydraulic structures from the effects of cavitation are divided into three groups: preventing the occurrence of cavitation; affecting the flow structure; ensuring cavitation resistance of the lining of structures. The article discusses some of these methods and solutions that reduce the effects of cavitation erosion. However, the problem of the negative impact of cavitation on hydraulic structures has still yet to be solved. An extensive number of methods for combating the negative effects of cavitation is considered in the scientific literature. Nevertheless, after analyzing both domestic and foreign literature, this problem remains insufficiently covered.

METHODOLOGY OF CALCULATION AND ORGANIZATION OF AUTONOMOUS POWER SUPPLY OF INDIVIDUAL FACILITIES VIA RENEWABLE ENERGY (IN MOUNTAINOUS AREAS)

Posted in 2021, ENGINEERING, Issue №9 (111) September 2021 | 0 comments

The current article proposes a methodology for calculating and organizing an autonomous power supply of individual objects from renewable energy sources in mountainous areas is proposed. The calculation is based on the energy ratios in the generator-storage-consumer system for various time intervals (hour, day, month, etc.), taking into account both daily and seasonal changes in the parameters of generation and consumption; a calculation algorithm is proposed.

The article examines the organization of autonomous energy supply to the consumers of renewable energy sources, which includes the main stages and parameters of the functioning of an autonomous energy complex (energy, man-made, environmental risks of mountainous zones) as well as their analysis from the point of view of possible deviations from the permissible limit values according to technological standards. Also, an algorithm for organizing autonomous energy supply from renewable energy to individual consumers is proposed taking into account the specifics of mountainous zones.
