Feed To Workpiece Given Machining Time Formula:
| From: | To: |
Feed To Workpiece Given Machining Time is a machining parameter that represents the distance the cutting tool advances along the length of the workpiece for every revolution of the spindle. It's a crucial parameter in machining operations that determines the material removal rate and surface finish quality.
The calculator uses the formula:
Where:
Explanation: The formula calculates the feed rate by dividing the total length of the workpiece by the product of machining time and spindle rotational frequency.
Details: Accurate feed calculation is essential for optimizing machining processes, ensuring proper material removal rates, achieving desired surface finishes, and maintaining tool life. Proper feed rates prevent tool breakage and ensure efficient machining operations.
Tips: Enter length of workpiece in meters, machining time in seconds, and rotational frequency of spindle in Hertz. All values must be positive numbers greater than zero.
Q1: What units should I use for the inputs?
A: Use meters for length, seconds for machining time, and Hertz for spindle rotational frequency. Ensure consistent units throughout the calculation.
Q2: How does feed rate affect machining quality?
A: Higher feed rates increase material removal rate but may reduce surface quality. Lower feed rates provide better surface finish but increase machining time.
Q3: What is the relationship between feed and spindle speed?
A: Feed and spindle speed together determine the cutting speed and material removal rate. They must be balanced for optimal machining performance.
Q4: Can this formula be used for all machining operations?
A: This formula is generally applicable for turning and milling operations where the tool moves linearly along the workpiece length.
Q5: How does feed rate affect tool life?
A: Excessive feed rates can cause rapid tool wear and breakage, while too low feed rates may cause rubbing instead of cutting, also reducing tool life.
