Cutting Speed

Cutting speed refers to how fast the laser cutting head moves along the cutting path, typically measured in inches per minute (IPM) or millimeters per minute. Optimal cutting speed depends on the material type, thickness, laser power, assist gas type, and desired edge quality, with thinner materials and higher laser power allowing faster speeds.

Too slow a cutting speed wastes machine time and introduces excessive heat that can distort surrounding material and create a wide heat-affected zone; too fast a speed produces incomplete cuts, dross, and ragged edges. Modern CNC laser systems automatically adjust cutting speed based on programmed material parameters, but experienced programmers understand the fine-tuning required to balance speed and quality.

Optimizing cutting speed is one of the most important factors in achieving both economic and quality objectives in laser cutting operations.
