Effect of Moisture Content and Cutting Speed on Shearing Properties of Four Almond Tree Varieties

In this research the effects of moisture content and cutting speed on the specific shearing energy and shearing stress for four variety of almond tree (Mamayy, Rabi, Sefid and Shahrodi12) was investigated and results the each any the varieties were compared with each other. Shear properties of almond wood varieties in this study, using a universal testing machine manufactured STM20 Sntam was determined. Knife bevel form of one-sided and edge angle is 40 degree.The characteristics at three moisture levels of 18, 25 and 45% (w.b.) wet basis, three cutting speed levels of 20, 30 and 40 mm/min and in three size 6, 9 and 12 mm were determined. The results of analysis of variance (ANOVA) showed specific shearing energy and shearing stress to all test factors were response significant (P
