Abstract
An automated method for cutting a plurality of hole features using a plasma arc torch system can be implemented on a computer numerical controller. The automated method can include the steps of: a) cutting a lead-in for a hole feature using a lead-in command speed based on a diameter of that hole feature and b) cutting a perimeter for the hole feature using a perimeter command speed greater than the corresponding lead-in command speed for the hole feature. The automated method can also include the step c) of repeating steps a) and b) for each additional hole feature having a same diameter or a different diameter.
