The effects of feed rate, cutting depth and rake angle on surface roughness and power consumption were investigated and modeled. Neuro-fuzzy methodology was applied and shown that it could be useful, reliable and an effective tool for modeling the surface roughness of wood.Thus, the results of the present research can be successfully applied in the wood industry to reduce time, energy and high experimental costs.展开更多

The results indicated: The variations of wood surface roughness had the effect on the wood color of some kinds of species of trees on working operation, with the surface roughness decreasing, the brightness and luminance exponent increased, the hue angle increased lightly, but the variation of color saturation was different to the different wood color hue of species of trees.展开更多

This paper presents an attempt to use Haralick method to evaluate manufactured wood surface roughness through the utilization of imaging processing and pattern recognition techniques. Through the use of the methodology presented in this paper, We can give features of wood surface by spatial dependence matrices. The preliminary results indicated that the method has the advantages of non-contact, three-dimensional, high-speed. This method can be used in classification and in-time measurement of manufactured wood products.展开更多

This paper gives an extensive review of methods used previously to measure wood surface roughness, and concludes that computer vision is the most suitable technique. The preliminary study shows that computer vision method has the advantages of a noncontact, three-dimensional measurement, high speed and well correlates with stylus tracing method. This method can be used in classification and in-time measurement of wood surface roughness after being improved.展开更多

Ten pointsbased mean roughness of the planed surface of Douglas, Hinoki, Beech and Padauk was measured by using the laser displacement meter and the stylus instrument to clarify the characteristics of both instrument. The measured roughness from the laser displacement sensor at the processing speed of 6 m·min-1 for forth wood specimens coincided with the value obtained from the stylus instrument by using a proportion coefficient between them.展开更多
