1. What is Total Cost of Tools Used?

Definition: This calculator determines the total cost of tools used by subtracting non-productive, machining, and tool changing costs from the total production cost.

Purpose: It helps manufacturing professionals understand the actual cost attributed specifically to tool usage in production processes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( c \) — Total cost of tools used
• \( C_p \) — Total production cost
• \( C_{np} \) — Total non-productive cost
• \( C_m \) — Total machining and operating cost
• \( C_t \) — Total tool changing cost

Explanation: The formula isolates the tool costs by removing other production-related expenses from the total production cost.

3. Importance of Tool Cost Calculation

Details: Accurate tool cost calculation helps in budgeting, cost control, and process optimization in manufacturing operations.

4. Using the Calculator

Tips: Enter all cost components in percentage values. The calculator will compute the tool cost percentage.

5. Frequently Asked Questions (FAQ)

Q1: What constitutes non-productive costs?
A: These include setup time, idle time, and other activities that don't directly contribute to production.

Q2: Why separate tool changing costs?
A: Tool changing involves downtime and labor costs that are distinct from actual tool usage costs.

Q3: How accurate is this calculation?
A: Accuracy depends on precise measurement of all cost components (±5% variation expected).

Q4: Can this be used for cost reduction analysis?
A: Yes, it helps identify areas where tool costs might be reduced without affecting production quality.

Q5: How often should this calculation be performed?
A: Regular calculation (e.g., monthly) helps track tool cost trends and efficiency improvements.
