Tool life observed during milling as the indicator of MDF machinability. The tool life in the wood industry is very different, depending on the cutting material and therefore tool life is one of the most important criteria for assessing the machinability. In the article this aspect of MDF machinability was tested and characterized. The results of experiments can be used in future for the comparing other materials to MDF in terms of machinability.
Galvanizing treatment as a method to protect tools used in teaching processes. This paper presents the use of zinc coating applied on surfaces of wood machining tools - exhibits in teaching processes. Analyses were conducted to determine resistance of applied coatings to the action of various environments, which in an accelerated manner assessed suitability of coatings as a method of tool protection, mainly in terms of their contact with users. Very advantageous effects of zinc coating application were observed in the analyzed variant. Galvanizing processes and the resulting coatings made it possible to identify defects in the material structure of the tools, being the most frequent results of intensive operation and wear.
The quality of the machined surface in the drilling process laminated chipboard. In this study trials were made eighteen durability tools for different values of the parameters analyzed cut. Based on the results obtained from the study, the influence of selected parameters on the cutting surface quality. Proposed mathematical models using ANOVA, allowing to estimate the surface quality in the test cutting process.The quality of the machined surface in the drilling process laminated chipboard.
