1. What is Tool Feed Speed?

Tool Feed Speed is the feed given against a workpiece per unit time in electrochemical machining processes. It represents the rate at which the tool advances toward the workpiece surface during the machining operation.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Feed Speed = \frac{\eta_e \times V_s \times e}{r_e \times \rho \times h} \]

Where:

Explanation: The formula calculates the optimal feed speed based on electrochemical machining parameters to maintain consistent material removal rate and machining quality.

3. Importance of Feed Speed Calculation

Details: Accurate feed speed calculation is crucial for maintaining proper gap control, achieving desired surface finish, ensuring dimensional accuracy, and optimizing machining efficiency in electrochemical machining processes.

4. Using the Calculator

Tips: Enter all parameters with appropriate units. Current efficiency should be between 0-1. All values must be positive numbers. The calculator will compute the optimal feed speed in meters per second.

5. Frequently Asked Questions (FAQ)

Q1: What is current efficiency in electrochemical machining?
A: Current efficiency is the ratio of the actual mass of material removed to the theoretical mass that should be removed according to Faraday's laws of electrolysis.

Q2: How does gap distance affect feed speed?
A: Smaller gap distances generally require slower feed speeds to maintain stable machining conditions and prevent short circuits between tool and workpiece.

Q3: What factors influence electrochemical equivalent?
A: Electrochemical equivalent depends on the workpiece material composition and valence of the metal ions involved in the electrochemical reaction.

Q4: Why is specific resistance of electrolyte important?
A: Electrolyte resistance affects current distribution and machining accuracy. Lower resistance electrolytes generally allow higher feed speeds.

Q5: How does workpiece density affect the calculation?
A: Higher density materials typically require slower feed speeds as more material mass needs to be removed per unit volume.
