1. What is Tool Life Calculation?

Tool Life calculation determines the period of time for which the cutting edge retains its cutting capacity between sharpening operations. It's a critical parameter in manufacturing processes to optimize tool usage and production efficiency.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L \) — Tool Life (Second)
• \( tb \) — Machining Time For Tool Life Production (Second)
• \( Nb \) — Batch Size (units)
• \( Nt \) — Number Of Tools Used (tools)

Explanation: The formula calculates tool life by dividing the total machining time (tb × Nb) by the number of tools used (Nt).

3. Importance of Tool Life Calculation

Details: Accurate tool life calculation is crucial for production planning, cost optimization, and maintaining consistent product quality in manufacturing processes.

4. Using the Calculator

Tips: Enter machining time in seconds, batch size as a positive integer, and number of tools used as a positive integer. All values must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect tool life?
A: Tool life is affected by cutting speed, feed rate, depth of cut, workpiece material, tool material, and cutting conditions.

Q2: How is tool life typically measured?
A: Tool life is typically measured by the actual cutting time until tool failure or until a predetermined wear criterion is reached.

Q3: What is considered a good tool life?
A: Good tool life varies by application but generally means the tool lasts through the required production run without excessive wear or failure.

Q4: How can tool life be extended?
A: Tool life can be extended by optimizing cutting parameters, using proper cooling/lubrication, selecting appropriate tool materials, and maintaining equipment.

Q5: Why is batch size important in tool life calculation?
A: Batch size determines the total production volume, which directly affects the total machining time and therefore the tool life calculation.
