Cutting performance of cemented carbide cutting tool in turning high-density fiberboard

摘要

In order to provide a scientific and reliable guidance for wood processing industry, the effects of cutting parameters on cutting forces, cutting temperature and tool wear were studied when turning high-density fiberboard by use of cemented-carbide cutting tools. The results showed that cutting forces (normal force and radial force) and cutting temperature are not affected by the cutting parameters in the same way: cutting forces decrease with increasing spindle speed, whereas cutting temperature increase with an increase of the spindle speed. However, there is a positive relation for cutting forces and temperature, to the feed per turn when cutting. The wear of the cemented-carbide cutting tool is shown by two mechanisms: Mainly adhesive wear but also abrasive wear, showed by loss of carbide-grains and by cracking and chipping, respectively. This study also indicated that higher-speed cutting is beneficial for wood-processing; evident by reduced energy for cutting and higher efficiency in production.
