The newest progress on whorl cutting technology is one kind has special geometry appearance (two tine have different outline) bit. This kind of combination makes the journey number that forms complete whorl decreases than odd tine cutting tool be as high as 40% , still added cutting tool life at the same time. Although it is told on the technology,be razor blade of a kind of many tine however, but the razor blade of whorl of dentition of twin of Snap Tap TT (with tall hill) overcame age more with the tradition cutting tool is relevant a problem of couplet, cause as a result of cutting muscularity namely brace up quiver. Compare with photograph of traditional razor blade, the length of cutting blade clench the teeth of TT razor blade is shorter, reduced cutting force and decrease brace up quivering risk. And as a result of the distance of form of the tooth on TT razor blade to the brim (T dimension) shorter, the whorl that is machined is OK more approach steps leading up to a house. Another advantage are TT razor blade be in the standard 16 model semifinished product is ground come out, so other that much tine razor blade needs norms the semifinished product with bigger, higher price. The key of efficiency of cutting of TT razor blade is a kind " rough machining tooth form / finish machining tooth form " design, among them rough machining tine compares precision work apparently come shortly. Accordingly, the deepness of lead whorl is a lot of less than the 2nd whorl. Anyhow, these tine are in go up somehow be the same as outline of finish machining dentiform is semmetry. The leading edge with the more perpendicular than showing photograph of the 2nd tine of the outline of the first tooth that cuts work and outline of finish machining of the whorl that finish. TT razor blade finishs two kinds of different cutting the cutting that is not two likeness that finish different deepness. Every tine is to be efficiency to undertake optimizing, and actually every tine cooperates to give complete tooth look with be being machined as soon as possible each other. Additional, every tine excision is almost identical alluding data will maintain the equilibrium that delivers a knife to be filled up. This is not to say this kind of new cutting blade external form wants a journey to be able to be machined only give a complete whorl, it excises one fraction only, volume general interest is equal, bit finishs radial feed through a few journeys.

08- - it is with 16UN whorl exemple compare feed. Whorl of tooth form of Snap Tap twin requires 4 travels, and cutting tool of traditional odd tooth form requires 7 travels. Feed forms a table 1 and 2 give out two kinds have representative cutting feed. 75% the distance of application and efficiency whorl is pitch, and TT arrives be being cheated so that let the position is pitch 100% to 135% . This is in the light of great majority application character consideration is normal let the position. TT razor blade is more businesslike than much tine razor blade because its position letting a knife is clear,be shorter (age bit amounts to pitch more normally 200% or more) . In fact, the efficiency that improve is considerable. It is for example in an experiment, the Snap Tap TT of qualitative grade of material of a CP500 with minutely 90 meters linear velocity uses 6 journeys cutting the BSW Whitworth whorl of every inches of 11 teeth of material of 316 stainless steel (diameter 1 inch, length 1 inch) , and the odd tine razor blade of CP500 material qualitative grade needs 11 journeys. Life of cutting tool of TT razor blade is taller, every cutting blade machines 640 and the life of odd tine cutting tool is 568. similar, the 2nd experiment is the TT bit that uses qualitative social estate of material of a CP500 with minutely 190 meters linear velocity is on mild steel workpiece turning 1.
5ISO whorl (9-mm is long) need 4 journeys. Be compared and character, corresponding odd tine cutting tool wants 7 routes. Every blade can machine TT razor blade 900, and traditional razor blade machines 600 only. CNC Milling
