1. What is Feed Of Workpiece Given Machining Time For Facing?

Feed is the distance the cutting tool advances along the length of the work for every revolution of the spindle. In facing operations, it determines how much material is removed per spindle revolution.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ f = \frac{ro - ri}{ns \times tm} \]

Where:

\( f \) — Feed (m)
\( ro \) — Outside Radius of The Workpiece (m)
\( ri \) — Inner Radius of Workpiece (m)
\( ns \) — Rotational Frequency of Spindle (Hz)
\( tm \) — Machining Time (s)

Explanation: The formula calculates the feed rate based on the radial distance to be machined, spindle speed, and available machining time.

3. Importance of Feed Calculation

Details: Accurate feed calculation is crucial for optimizing machining processes, ensuring proper material removal rates, achieving desired surface finish, and maintaining tool life in facing operations.

4. Using the Calculator

Tips: Enter outside radius and inner radius in meters, rotational frequency in hertz, and machining time in seconds. All values must be valid (positive numbers, outside radius > inner radius).

5. Frequently Asked Questions (FAQ)

Q1: Why is feed important in machining?
A: Feed directly affects material removal rate, surface finish quality, tool wear, and overall machining efficiency.

Q2: What are typical feed values in facing operations?
A: Feed values vary based on material, tool type, and machine capability, typically ranging from 0.05 to 0.5 mm/rev.

Q3: How does feed relate to surface finish?
A: Lower feed rates generally produce better surface finish but increase machining time, while higher feeds reduce time but may compromise finish quality.

Q4: What factors influence optimal feed selection?
A: Material hardness, tool material, cutting depth, machine rigidity, and desired surface finish all influence optimal feed selection.

Q5: Can this formula be used for other machining operations?
A: While specifically for facing, similar principles apply to other turning operations with appropriate adjustments for cutting geometry.
