How to calculate the feed center feed speed
The selection of the tool and the determination of the cutting quantity are the important contents in the numerical control processing technology. It not only af
Feed speed also has two G94 F100 means a minute distance of 100 mm. The other is G95 F0.1 that the spindle per turn, the tool feed size of 0.1 mm. Selection of Cutter and Determination of Cutting Volume in NC Machining
spindle speed: one is G97 S1000 said a minute spindle rotation of 1000 laps, which is commonly referred to as constant speed. The other is the G96 S80 is constant linear velocity, is determined by the workpiece surface spindle speed.
Spindle speed = 1000Vc / πD 2: Maximum cutting speed of the tool (Vc): high speed steel 50 m / min; superhard tool 150 m / min; coating tool 250 m / min; ceramic diamond tool 1000 m / Min 3 machined alloy steel Brinell hardness = 275-325 high speed steel tool Vc = 18m / min; carbide cutting tool Vc = 70m / min (eat knife volume = 3mm; feed f = 0.3mm / r)
