Outside Cutting
Used to cut sheet directly from the outside without piercing it.
It mainly used in cutting thick sheets or parts with high precision.
Cool Delay
Blowing time at cooling point.
Cooling Air
The used gas during blowing.
6.5.6 Over-arris Parameters
Setting over-arris parameters is used to avoid over-burning from uneven
distribution of laser energy on faces and arrises during cutting a rectangular tube.
In cutting a rectangular tube, rotation of the tube causes the uneven distribution of
laser energy on faces and arrises. Then over burning occurs. Setting over-arris
parameters is used to solve the problem.
Peak Power
Used to set peak current during over-arris cutting by adjust the laser device via the
analog quantity.
Air Pressure
The pressure ofauxiliary gas during over-arris cutting.
It should be used together with proportional valve or multi-valve.
Cut Frequency
The carrier frequency of PWM modulate signals during over-arris cutting, namely
the light emission times in one second.
Over-arris Height
The distance between the nozzle and the material during over-arris cutting.
Duty Cycle
In per unit pulse cycle, the ratio of light output time to the unit pulse cycle time.
Sensitivity
The sensitivity of the cutting head during over-arris cutting.
Over-arris Speed
The cutting speed during over-arris cutting.
