Abstract

Drilling is still one of the basic cutting processes that are of particular interest to wood science and technology professionals. As a result, considerable (and very diverse thematically) research has been recently carried out on drilling. The article focuses on the new and quite spectacular approach to drill condition monitoring in wood-based panels machining. One of the most innovative elements in the analyzed research trend is the adoption of the new general methodological assumptions that allow one to define the drill condition monitoring problem as a standard three-class classification. The general effectiveness of the tested monitoring systems (accuracy of classification ACC [%]), ranged between 67% and 82%. The critical classification error (CCE [%]) ranged between 0% and 1.6%. These results seem very promising, yet are still not good enough to develop a commercial monitoring system. A more useful form of obtaining diagnostic data and more effective classification strategies (algorithms) are likely to be required.

Highlights

Drilling in Wood-Based Panels withThe technique of wood drilling has a long history that dates to the Upper PaleolithicPeriod [1] with numerous developments made in this field during these centuries/millennia [2]
From a practical standpoint, quite impossible to imagine the manufacturing of furniture and other interior elements or construction of wooden buildings without effective drilling techniques
The fundamental and traditional research direction, was to study the problem of increasing the hole quality. These studies most often focused on the delamination factor [3] and surface roughness [4,5] in wood-based panel drilling

Summary

Introduction

Drilling in Wood-Based Panels withThe technique of wood drilling has a long history that dates to the Upper PaleolithicPeriod (about 40,000 years ago) [1] with numerous developments made in this field during these centuries/millennia [2]. Drilling is still one of the basic cutting processes that are of particular interest to wood science and technology professionals. Considerable (and very diverse thematically) research has been recently carried out on drilling. The fundamental and traditional research direction (which resulted in a significant development of practical knowledge), was to study the problem of increasing the hole quality. These studies most often focused on the delamination factor [3] and surface roughness [4,5] in wood-based panel drilling. The drill deflection problem (which is the main cause of the hole position error) has recently been analyzed in an innovative way [6,7,8]
