ABSTRACT

The main factor influencing tool life in particleboard machining is mineral content, and therefore the aim of this investigation is to study the issue and evaluate the tool lifetime by machining different particleboards Also, the change of the mineral content of particle boards over a time frame of 30 years and the geographic origin of the boards should also be taken in account. For this purpose, the mineral content was determined on 600 samples which were produced between 1989 and 2018 in different countries. The influence of the mineral content to tool lifetime was examined with cutting tests at a special series of industrially produced boards with known recycled wood composition. Machining conditions and cutting material have been the same during the investigation. A comparison of the amount of recycled wood which is used in production of particleboard showed a higher mineral content for an increasing proportion of recycled wood, and thereby also an increased wear on the tools.

摘要

刨花板加工中影响刀具寿命的主要因素是矿物质含量，因此本次调查的目的是研究这个问题并通过加工不同的刨花板来评估刀具寿命。此外，刨花板的矿物质含量在30 年和董事会的地理起源也应考虑在内。为此，对 1989 年至 2018 年间在不同国家生产的 600 个样品进行了矿物含量测定。矿物含量对工具寿命的影响通过对一系列工业生产的具有已知回收木材成分的特殊板材进行切割测试来检验。加工条件和切削材料在调查期间是相同的。
