What is التفريز باستخدام الحاسب الآلي الرقمي?
CNC milling is a subtractive manufacturing process that uses computer-controlled rotary cutters to remove material from a workpiece. Unlike traditional manual milling, CNC milling automates the entire process, allowing for intricate designs and highly accurate results.
The CNC Milling Process
The CNC milling process consists of several key steps:
- CAD Design – Engineers create a 3D model of the desired part.
- CAM Processing – The CAD file is converted into G-code, which provides instructions for the CNC machine.
- Material Setup – The raw material is clamped onto the machine’s worktable.
- Milling Execution – The spindle rotates the cutting tool, removing material layer by layer.
- Final Inspection – Quality control ensures the part meets required specifications.
Types of CNC Milling Operations
- Face Milling – Cutting a flat surface on the workpiece.
- Peripheral Milling – Machining along the edges of a workpiece.
- Slot Milling – Creating narrow channels or grooves.
- Drilling & Boring – Precision hole-making operations.
- Thread Milling – Cutting screw threads with high accuracy.
Why CNC Milling is Essential
- Unmatched Precision – CNC milling can achieve tolerances as tight as ±0.001 inches.
- Repeatability – Every part produced is identical, reducing errors.
- Speed & Efficiency – Automates complex machining, cutting production time significantly.
- Versatility – Works with various materials, from metals to plastics.
- Reduced Waste – Optimized cutting paths minimize material usage.
Industries That Rely on CNC Milling
- Aerospace – Producing lightweight yet strong aircraft components.
- Automotive – Machining engine parts and transmission components.
- Medical – Manufacturing prosthetics and surgical instruments with high precision.
