Концепции повышения производительности и снижения технологической себестоимости механической обработки деталей машин

Abstract

Приведены результаты исследований производительности и технологической себестоимости обработки сборными твердосплавными лезвийными инструментами с износостойкими покрытиями фирмы Iscar, позволяющими более чем в два раза уменьшить трудоемкость обработки и суммарные затраты по сравнению с применяемыми отечественными инструментами. Эффект достигается увеличением скорости резания и подачи вследствие повышения износостойкости и теплостойкости инструментов фирмы Iscar.

Наведено результати досліджень продуктивності та технологічної собівартості обробки збірними твердосплавними лезовими інструментами зі зносостійкими покриттями фірми Iscar, що дозволяють більш ніж в два рази зменшити трудомісткість обробки і сумарні витрати порівняно із застосовуваними вітчизняними інструментами. Ефект досягається збільшенням швидкості різання і подачі внаслідок підвищення зносостійкості та теплостійкості інструментів фірми Iscar.

In the theory the basic conditions reduce the cost of processing technology and improve productivity through the use of modern cutting tools produced by leading foreign firms of instrumental. Theoretically, it found that an increase in the cost of processing performance varies depending on the extreme, passing the minimum point. Reduce the minimum processing cost value may be due to the increase of productivity using cutting edge tools, characterized-ized by a high capacity for work in high cutting temperatures. The criterion for assessing the achievement of practical processing cost low cost attitude is common to use on workers' wages to the cost of the cutting tool, which takes quite a specific value for a variety of processing conditions. To analyze the possibilities of practical use of the proposed criterion, a complex of experimental researches of technological and cost of processing teams carbide blade cutting tools with wear-resistant coatings company Iscar. It has been established that their use allows for more than twice to reduce the complexity of processing and overall costs compared to traditionally used domestic blade carbide tools. It has been shown that the treatment effect is achieved by increasing the cutting speed and feed due to increased wear resistance and heat resistance values of the company Iscar tools. It was established that during milling the implementation of more features low processing cost than when turning. Moreover, this condition is also taking into account all major cost items, including the cost of workers' wages, cutting tools, equipment and pro-Chie costs, allowing more correctly estimate the cost-effectiveness of mechanical processing, as It accounts for the largest number of cost items. The experiments, experimentally confirmed that the main condition for reducing the processing cost to its minimum value is to increase the processing performance through the use of a heat-resistant and wear-resistant tungsten carbide cutting tools. Practical recommendations for improving the machining of machine parts.
