Feed per tooth calculator

Comprehensive Threading CalculatorsEfficient and accurate threading is essential in machining, whether you’re performing internal or external threading. Here, you'll find a complete set of threading calculators designed for machinists and engineers, covering threading RPM, pitch, feed rate, milling, cutting speed, and thread rolling diameter calculations. Use these tools to streamline setup and achieve precise, high-quality threads on any material. Each calculator includes formulas for clarity and to ensure accuracy in different threading operations.1. Threading RPM CalculatorCalculate the ideal RPM for threading operations based on surface speed and thread diameter. Proper RPM selection helps maintain thread quality and prevent tool wear.Formula: RPM = (1000 × Surface Speed) / (π × Diameter)Surface Speed (m/min): Thread Diameter (mm): 2. Threading Calculator (Pitch)Determine thread pitch based on threads per inch (TPI) for precise threading requirements. Pitch is crucial in setting accurate lead distances and thread profile specifications.Formula: Pitch = 25.4 / TPIThreads per Inch (TPI): 3. Thread Milling CalculatorThis calculator helps you find the correct feed rate for thread milling operations, factoring in spindle RPM, feed per tooth, and the number of flutes.Formula: Feed Rate = RPM × Feed per Tooth × Number of FlutesSpindle RPM: Feed per Tooth (mm): Number of Flutes: 4. Threading Speed and Feed CalculatorCalculate both RPM and feed rate in threading operations based on surface speed, diameter, and TPI. Proper speed and feed rates are critical for achieving optimal thread integrity.Formulas:RPM = (1000 × Surface Speed) / (π × Diameter)Feed Rate = RPM / TPISurface Speed (m/min): Diameter (mm):

Therefore, it is necessary to compromise and select the speed that best apply to the material. Large deviations will result in a shorter life and reduced cutting ability. Too low a speed is always better than too high a speed.If the deviations are too large, a frequency changer can be installed in order to get variable speeds. A frequency changer can be installed by most electricians.Speed, Feed & Tooth AnglesSpeeds are listed in SFPM (surface feet per minute).Feeds are listed in inches per minute.SFPM can be changed to RPM (revolutions per minute) based on the blade diameter as follows:RPM = SFPM x 3.819 divided by the blade diameter in inchesFeedChip load per tooth is independent of the speed. The correct feed can theoretically be calculated from a chip load of 0.004″(0.1mm) per tooth per revolution. In practice, the maximum feed is determined by the stability of the machine, the clamping and the capability of the motor. The chips are also an important factor determining the feed and they should always be the correct color and shape. Basic feeds listed in inches per minute can be found in the table on the previous tab. This is the basic feed and it can and should be increased by production cutting on stable machines or by using special blades.ChipsToo low a feed:Proper chips are not formed, only “metal crumbs”.The blade is worn excessively and life is reduced.Too high a feed:Discolored chips that weld in the gullets.There is great risk that the blade will break.The correct feed:The chips are nicely rounded, uniform and bright.Maximum use and benefit of the blade.Chips:FluidsFluid is used for cooling, flushing away chips and lubrication.Use a recognized product and follow the suppliers instructions carefully. Sawing is a “hard” machining process that demands a mixture of 6-10%.Fluids should be applied in generous amounts on both sides of the blade during cutting. The nozzles must be pointed directly at the cutting point. The cutting process must never be commenced without fluids. If it is, the tooth tips will burn or “pick up” may occur, either of which reduces blade life substantially.Stability in fixture/viceA stable circular saw is the most important basis for obtaining good cutting results.Stability must be present in the machines main bearings, column and vice. A lack of stability leads to vibrations in the machine and/or

Trace allows you to machine 3D Edge contours. You can select Edges from the model or Sketch geometry. This single line engraving can be used for scroll work or text. You can machine on center or use left and right compensation. Using left and right compensation might create disconnected passes at the corners due to sudden changes in the Z position.
