Feed Formula:
| From: | To: |
The feed formula calculates the distance the cutting tool advances along the length of the workpiece during cylindrical turning operations. It is derived from the relationship between workpiece diameter, length of cut, and machining conditions.
The calculator uses the feed formula:
Where:
Explanation: The formula calculates the feed rate based on the geometry of the workpiece and specific machining conditions represented by the constant K.
Details: Accurate feed calculation is crucial for optimizing machining processes, ensuring proper tool life, achieving desired surface finish, and maintaining dimensional accuracy in cylindrical turning operations.
Tips: Enter diameter of workpiece in meters, length of cut in meters, and constant for machining condition in meters. All values must be positive numbers greater than zero.
Q1: What is the constant K in the formula?
A: Constant K represents the distance moved by the tool corner relative to the workpiece during a particular machining condition and is specific to the machining setup.
Q2: How is the constant K determined?
A: The constant K is typically determined through experimental measurements or provided by machine tool manufacturers based on specific machining parameters.
Q3: What are typical feed values in machining?
A: Feed values vary significantly based on material, tool type, and machining conditions, typically ranging from 0.05 to 0.5 mm/rev for most turning operations.
Q4: How does feed affect machining quality?
A: Proper feed selection affects surface finish, tool wear, machining time, and dimensional accuracy. Too high feed can cause poor surface finish, while too low feed can increase machining time excessively.
Q5: Can this formula be used for other machining operations?
A: While derived for cylindrical turning, similar principles apply to other machining operations, though specific constants and formulas may vary.
