| Research Abstract |
For the purpose of making the machinability of constructive sugi LVL clear, circular sawing tests were conducted. From the experimental results, the following results were clarified. 1) Tool wear progression for cemented-carbide tipped saw in circular sawing of constructive sugi LVL was slower than that for lauan plywood (Type II) and faster than coniferous plywood. 2) The proper sharpness angle of cemented-carbide tipped saw for constructive sugi LVL was approximately 65 degrees (cutting angel : 85 degrees). 3) The tool wear progression for cemented-carbide tipped saw in circular sawing of constructive sugi LVL was the slowest at K01.
