Analisis Gaya Spesifik Pemotongan Sabut Kelapa Muda (Cocos Nucifera)

To design a young coconut trimming machine, it's important to analyze the cutting mechanism of young coconut husk. The aim of this study were to analyze the cutting mechanism of young coconut husk and generate mathematical model of specific cutting force. Sharpening angle, cutting angle and sharpened knife were optimized to get the lowest cutting force. Mathematical model has been generated to estimate the maximum cutting force for one side sharpened knife and two side sharpened knife with cutting angle (θ) at 0Oand above 0O. Based on the analysis of this study, the type of knife that require the lowest cutting force is two side sharpened knife with sharpening angle (β) = 10O and cutting angle (θ)= 30O
