Traverse Speed in Horizontal and Vertical Spindle Surface-Grinder given MRR Calculator

Traverse Speed Formula:

\[ V_{trav} = \frac{Z_w}{f \times d_{cut}} \]

Traverse Speed (m/s):

1. What is Traverse Speed in Surface Grinding?

Definition: Traverse speed refers to the reciprocating back-and-forth motion of the worktable that holds the workpiece during surface grinding operations.

Purpose: It is crucial for achieving desired shape, dimensional accuracy, and surface finish during grinding operations.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V_{trav} = \frac{Z_w}{f \times d_{cut}} \]

Where:

\( V_{trav} \) — Traverse speed of work table (m/s)
\( Z_w \) — Metal removal rate (m³/s)
\( f \) — Feed rate (m/rev)
\( d_{cut} \) — Depth of cut (m)

Explanation: The metal removal rate is divided by the product of feed rate and depth of cut to determine the optimal traverse speed.

3. Importance of Traverse Speed Calculation

Details: Proper traverse speed calculation ensures efficient material removal, prevents wheel overloading, and maintains surface quality.

4. Using the Calculator

Tips: Enter the metal removal rate in m³/s, feed rate in m/rev (default 0.7 ±5%), and depth of cut in m (default 0.0145 ±5%). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is feed rate given with ±5% tolerance?
A: The ±5% accounts for normal variations in machine performance and setup conditions.

Q2: What affects metal removal rate in grinding?
A: MRR depends on wheel speed, workpiece material, wheel grit, and coolant conditions.

Q3: How does depth of cut affect traverse speed?
A: Deeper cuts typically require slower traverse speeds to maintain wheel integrity.

Q4: What's a typical traverse speed range?
A: For surface grinding, traverse speeds typically range from 0.05 to 0.5 m/s.

Q5: How do I measure metal removal rate?
A: MRR can be calculated by measuring workpiece volume before and after grinding over a known time period.
