CNC Machining Knowledge

What is CNC machining?
CNC (Computer Numerical Control) machining is a manufacturing process where pre-programmed computer software dictates the movement of factory tools and machinery. This process can control a complex series of operations like turning, milling, and drilling with high precision.
What's the difference between 3-axis and 5-axis CNC machining?
3-axis CNC machines move along three linear axes (X, Y, and Z), suitable for simpler parts. 5-axis machines add two rotary axes, allowing tool access from multiple angles, ideal for complex geometries and reducing setups.
What is the difference between milling and turning?
Milling uses rotating cutting tools while the workpiece remains stationary, ideal for creating flat surfaces, slots, and complex 3D shapes. Turning rotates the workpiece while a stationary cutting tool removes material, perfect for creating cylindrical parts.
What factors affect CNC machining cost?
Key factors include material type and cost, part complexity, tolerances required, surface finish specifications, quantity ordered, and setup time. Design optimization can often reduce costs significantly.
What is Design for Manufacturing (DFM)?
DFM is the practice of designing parts with manufacturing processes in mind. It involves considering factors like material selection, part geometry, tolerances, and surface finishes to ensure efficient and cost-effective production.
