II.Experimental Results
A.The Results of the Design
In the first stage of the experiment, three designs were made: a straight blade, a curved blade, and a shaped blade. The straight blade design had the least amount of surface area. The curved blade had a wider range of surface area, while the shaped blade had a larger surface area than the straight blade but a smaller surface area than the curved blade. All three blades had the same width, depth and groove depth.
In the second stage of the experiment, the three blades were tested in a CNC machine. The results obtained showed that the straight blade was the most efficient, with a cutting time of 16.7seconds, followed by the curved blade (17.1seconds) and the shaped blade (19.5seconds). The straight blade had the highest surface quality of the three blades, while the curved blade had the highest surface finish. The shaped blade had the lowest surface quality.
B.The Results of the Cutting
In the third stage of the experiment, the blades were tested for their cutting effectiveness. The results showed that the straight blade had the highest efficiency of the three, achieving a cutting speed of 39.7m/min and a cutting depth of 0.25mm. The curved blade had a cutting speed of 38.9m/min and a cutting depth of 0.23mm. Lastly, the shaped blade had a cutting speed of 37.1m/min and a cutting depth of 0.20mm.
C.Summary
Overall, the results of this experiment indicate that the straight blade design is the most efficient for the purpose of root clearing. Of the three blades tested, the straight blade had the highest cutting speed and the best surface quality. The curved blade had the highest surface finish, while the shaped blade had the lowest surface quality. The experiment also showed that CNC machines had a higher efficiency in cutting than traditional cutting methods. This makes CNC machines the perfect tool for root clearing, and for other applications where cutting speed and surface quality are important.
