1. What is Total Cost of Tools used given Average Production Cost?

Definition: This calculator determines the total cost of tools used in production based on batch size, production costs, tool costs, and time factors.

Purpose: It helps manufacturers and production planners estimate tooling costs for production batches.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( t \) — Total tool cost
• \( N_b \) — Batch size
• \( C_{pr} \) — Production cost of each component
• \( C_t \) — Cost of a tool
• \( t_s \) — Setup time per component
• \( t_m \) — Machining time per component
• \( N_t \) — Number of tools used
• \( t_c \) — Time to change one tool

Explanation: The formula accounts for tool costs spread across the batch, including setup, machining, and tool change times.

3. Importance of Tool Cost Calculation

Details: Accurate tool cost estimation helps in pricing products competitively, budgeting for production runs, and evaluating production efficiency.

4. Using the Calculator

Tips: Enter all required values with ±5% tolerance. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why include ±5% in the inputs?
A: The 5% tolerance accounts for typical variations in production parameters.

Q2: How is production cost per component determined?
A: It includes material costs, labor, machine time, and overhead allocated per unit.

Q3: What affects tool change time?
A: Factors include tool complexity, machine type, and operator skill level.

Q4: When would batch size significantly impact tool costs?
A: In small batches where tool costs aren't amortized over many units.

Q5: How can I reduce total tool costs?
A: By extending tool life, reducing change times, or optimizing machining parameters.
