Medium Density Fiberboard Machining and Wear Behavior of Injection‐Molded Ceramic Composite Wood Cutting Tools

Abstract

Wear behavior of four different ceramic composite cutting tools was studied in peripheral milling of medium density fiberboard. Tools were previously manufactured by near net-shape ceramic injection molding with subsequent debindering and sintering. Cutting edge rounding and recession were investigated for defined cutting parameters and distinct cutting distances. Cutting forces were measured dependent on tool material and feed travel. Wear characteristics of ceramic cutting tools were investigated by SEM. Ceramic injection-molded tools were successfully applied in wood-machining operations. Wear mechanisms changed with different ceramic composites used. Results of microchamfered ACY tools showed superior lifetime compared with standard WC-Co tools.

Effects of geometric angle and cutting speed on cutting forces and tool wear of ceramic cutting tools during peripheral up‐milling of high‐density fiberboard

“…Currently, in the wood machining industry, cemented carbide tools have been most frequently applied as they provide good blend of hardness and toughness at a reasonable price [5]. However, cemented carbide tools fail to meet the need of high speed cutting, consistent cutting quality and long service life in modern wood machining, because they are vulnerable to high centrifugal force from high spindle rotation and the mineral contents in wood-based material such as acids, hydrocarbons and tannins which will react with them easily [6][7][8][9]. Consequently, these lead to strong corrosion in the cutting area of the tools.…”

“…Thus, taking the lifetime of the cutting tools, the efficiency of the industrial production and the quality of the product into consideration, manufacturers are actively seeking other alternative for machining wood-base material. Diamond cutting tools, with their excellent hardness, offering improved service life, are an ideal cutting tools for wood-base materials machining, but their high prices make diamond cutting tools themselves less interesting [9].…”

Cutting performance of cemented carbide cutting tool in turning high‐density fiberboard

“…Among them, ceramic cutting tools are seldom applied in wood processing due to its poor toughness [9]. Diamond cutting tools with the highest hardness of 10.000 HV are used by a number of enterprises, but the heavy price raises the production cost seriously [10]. Cemented carbide cutting tools, as the most widely used wood cutting tools, consist primarily of a large volume fraction of fine grain refractory metal carbide in a metal binder, which have shown incomparable advantages.…”

“…Thirdly, their heat resistance means cemented carbide cutting tools can retain excellent physical and mechanical properties at elevated cutting temperatures. Finally, its price is attractive to most enterprises [11][12][13][14].…”
