Abstract
The shearing experiments of honey/wax matrix were performed with two different sets of full scale paired knives: a wedge-shaped knife system (375 mm long) and a panel knife system (200 mm long), at different shearing velocities. To compare experimental results, the data were recalculated to the length of paired knives of 430 mm as the typical dimension of a frame. Increase in the double wedge-knife velocity from 300 mm/min to 600 mm/min caused an increase in the apparent shearing forces from the range of 195-400 N to the range of 380-600 N, respectively. If the shearing force in the double panel knife is recalculated to the full length of a frame of 430 mm, the expected force magnitude would be in the range of 730-1150 N at the shearing velocity of 300 mm/min. The range of forces that damaged the foundation overlapped the range of the cutting forces occurring during the shearing process with the panel knife. Factors influencing the damaging of a foundation were: wax foundation age, cleanliness of the blade surface, sharpness of the cutting edge, and the presence of cocoons.
