Introduction:
CNC (Computer Numerical Control) machining is a versatile and efficient method for manufacturing precision parts. To effectively manage production costs, it’s crucial to calculate CNC machining expenses per hour. In this article, we’ll explore how to determine the cost per hour, allowing you to optimize your machining operations.
Formula:
The CNC machining cost per hour can be calculated by adding several components:
Cost Per Hour = Machine Rate + Tooling Cost + Labor Cost
How to Use:
- Enter the machine rate (in USD per hour) into the “Machine Rate” field.
- Input the tooling cost (in USD per hour) in the “Tooling Cost” field.
- Specify the labor cost (in USD per hour) in the “Labor Cost” field.
- Click the “Calculate” button.
- The estimated CNC machining cost per hour will be displayed.
Example:
Let’s say you have a machine rate of $50 per hour, tooling costs of $10 per hour, and labor costs of $25 per hour. The CNC machining cost per hour would be:
Cost Per Hour = $50 (Machine Rate) + $10 (Tooling Cost) + $25 (Labor Cost) = $85 per hour
