Abstract
Milling a chipboard with a high-speed steel tool. In the paper the results of investigations of wear of a high-speed steel double-bit mill during milling of melamine-faced chipboard are presented. Experimental investigations also identified the effect of the cutting speed and feed per tooth on the value of force parameters in the cutting process as well as on the value of the factor of the chipboard edge delamination. The significance of the effect of cutting process parameters and tool wear on the value of the delamination factor was determined using multivariate analysis of variance. Delamination is the main damage observed during the machining of chipboard. A statistical analysis of the experimental results indicates that the main parameters determining the degree of damage to the chipboard edges are the wear of the tool flank and the cutting speed. Furthermore, the economic cutting speed and the cutting speed corresponding to the maximum efficiency of the milling process are evaluated. The value of the economical cutting speed can be obtained on a standard CNC machine. The cutting speed that ensures the maximum efficiency exceeds the maximum cutting speed that it is possible to obtain on a standard CNC woodworking machine.
