The high definition and precision of a laser-cutting process increases its sensitivity to small disturbances from Mother Nature, namely, temperature, humidity, barometric pressure, and pollution levels inside a facility. Adverse environmental conditions may feel uncomfortable for humans, but most industrial laser machines are designed to operate at both ends of extreme conditions of temperature, atmospheric pressure, and humidity. However, the processes generally respond to variations in environmental conditions with variations in outputs. Process parameters and methods must be as tolerant as possible to such variations, or they must be optimized with each condition change. Good documentation over the years can reveal the true impact of weather on operations, downtime, productivity, profitability, and quality.
