How Do Okuma CNC Machines Work?
Step-by-Step Overview
- Design Creation
- The process begins with a digital design of the desired part, created using CAD (Computer-Aided Design) software.
-
This design is then converted into a CNC program using CAM (Computer-Aided Manufacturing) software.
-
Programming the Machine
- The CNC program, usually in G-code, is uploaded to the Okuma machine’s OSP control system.
-
The commands in the program dictate every movement of the machine – from cutting and drilling to tool changes and speed adjustments.
-
Setting Up the Machine
- Material (workpiece) is loaded onto the machine’s bed or chuck.
- Tools are installed and calibrated for precise operations.
-
Operators check offsets and verify tool paths to ensure correctness.
-
Running the Job
- The operator starts the machine and supervises the cutting or shaping operations.
-
The Okuma system executes the programmed instructions with precision, often allowing for multi-tasking with advanced models.
-
Quality Check
- Finished parts are measured using metrological tools to confirm they meet required specifications.
- Any necessary adjustments are made for consistent, high-quality production.
