- Step-by-step Workflow
Our CNC Machining Process
We align part programming, fixture planning, and inspection cycles to deliver consistency across production batches for large-format components.
Advanced algorithms optimize tool paths, minimizing tool wear, reducing cycle times, and improving surface finishes. This involves strategically planning the sequence of movements and cuts to enhance efficiency.
Modern CNC machines often utilize 5-axis or even 6-axis capabilities, allowing for complex geometries and intricate shapes. This reduces the need to reposition the part, ensuring higher accuracy and a more refined finish.
CNC machines may integrate adaptive cutting strategies, where cutting conditions (speed, feed, depth of cut) adjust dynamically based on real-time sensor feedback or cutting force monitoring. This helps prevent tool breakage and ensures optimal material removal rates.
Specialized techniques like high-speed machining enable faster spindle speeds and advanced feed rates. This increases material removal rates while maintaining fine tolerances and reducing thermal distortion.
Some CNC setups incorporate in-process measuring systems (like laser scanners or probe-based systems) to check the part’s dimensions as it’s being machined. These systems can send real-time data back to the machine, allowing for automatic adjustments during production.
CNC machines with automated tool changers enhance efficiency by switching tools automatically without operator intervention. This allows for uninterrupted multi-operation machining without downtime, improving productivity in complex jobs with several cutting tools.
