1. What is Cutting Ratio?

The Cutting Ratio is defined as the thickness of metal before cutting to the thickness of metal after cutting. It is a fundamental parameter in machining processes that helps determine material removal efficiency.

2. How Does the Calculator Work?

The calculator uses the Cutting Ratio formula:

Where:

• \( r_c \) — Cutting Ratio
• \( a_c \) — Undeformed Chip Thickness (m)
• \( t_1 \) — Uncut Chip Thickness (m)

Explanation: The cutting ratio represents the relationship between the chip thickness before and after the cutting process, indicating how much the material is compressed during machining.

3. Importance of Cutting Ratio

Details: The cutting ratio is crucial for understanding material behavior during machining, predicting cutting forces, optimizing tool geometry, and improving surface finish quality in manufacturing processes.

4. Using the Calculator

Tips: Enter both undeformed chip thickness and uncut chip thickness in meters. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical range for cutting ratio values?
A: Cutting ratio typically ranges from 0.1 to 0.8, depending on the material being machined and cutting conditions.

Q2: How does cutting ratio affect machining performance?
A: Higher cutting ratios generally indicate better material removal efficiency, while lower ratios may suggest excessive material compression and higher cutting forces.

Q3: What factors influence the cutting ratio?
A: Cutting ratio is influenced by workpiece material properties, tool geometry, cutting speed, feed rate, and cutting fluid application.

Q4: Can cutting ratio be greater than 1?
A: Typically, cutting ratio is less than 1 as the chip thickness after cutting is usually greater than the uncut chip thickness due to material compression.

Q5: How is cutting ratio measured experimentally?
A: Cutting ratio can be measured by comparing the actual chip thickness after cutting with the theoretical uncut chip thickness using precision measuring instruments.
