Abstract

A two-dimensional geometric theory for maximizing lumber yield from logs was developed. Centered cant sawing solutions for both circular and elliptical shaped logs were derived. Sawline placement for maximum yield is dependent upon the diameter of round logs or upon the cross-sectional axis of elliptical logs. The width of the face of the cant is equal to 0.707 times the diameter or parallel-axis of the log. Slab thickness is equal to 0.147 times the diameter or perpendicular-axis of the log. It assumes circular and elliptical log shapes and provides a method that may substantially reduce computation time when applied to computerized log breakdown decisions, samples.

Özet

Tomruktan maksimum kereste randımanı elde etmek için iki boyutlu geometrik teori geliştirildi. Daire ve elips şeklindeki tomrukların merkezileştirilmiş prizma biçme çözümleri elde edilmiştir. Maksimum randıman için biçme hattınm yerleşimi yuvarlak tomrukların çapma veya elips şeklindeki tomrukların enine kesit eksenine bağlıdır. Prizma yüzeyinin genişliği 0.707 x tomruğun paralel ekseni veya çapı'na eşittir. Kapak tahtası kalınlığı 0.147 x tomruğun dik ekseni veya çapı'na eşittir. Teori daire ve elips tomruk biçimlerini varsayar ve bilgisayarlı tomruk işleme kararlan uygulandığı zaman hesaplama zamanını tatmin edici düzeyde azaltan bir metot sunar.
