37 CypCut Laser Cutting Control System
plate will stay in the "Reference height", and follow cutting after
detecting in the board. Commonly is used for cutting metal plate.
The setting pattern of "Reference height" is that save the parameters
by the path of “CNC” _ “BCS100” _ “save reference height when follow
outside plate”, when the laser head move to the appropriate height.
③ Piercing mode
Direct Cutting
Piercing and cutting use the same parameters, which are commonly
used for thin board cutting.
Two stages piercing
Piercing and cutting use the same parameters, which are commonly
used for thick board cutting,. You can choose whether needs
progressive piercing.
Progressive piercing
Based on stage piercing, the piercing method of variable defocusing
amount is used, i.e., slowly fall when piercing, and this method is
commonly used for thick board cutting. During stage piercing, the
piercing time can be set to be a small value, such as 100MS. At this
time, actual piercing time = 100MS + the time required for slowly
falling to the cutting height from the piercing height.
Three stages piercing Based on stage piercing, conduct another stage piercing. You can
choose whether needs progressive piercing. And this method is
commonly used for thick board cutting
④ Cutting Parameters
Cutting Height
Set the height from the laser head to the board during cutting.
Cutting Gas
Set the type of auxiliary gas used in cutting.
Cutting Pressure
Set the pressure of auxiliary gas during cutting, and use it with
proportional valves or multiple valves.
Peak Current
Set the peak current of fiber laser, i.e., diode power. Peak power
determines the maximum cutting power that machines can reach. As
for a cutting machine with a power of 500W, if its diode current is set
to be 80%, the diode power it can reach during cutting is 500W *
80% = 400W.
Cutting Power
Set the laser power used in cutting, i.e., the duty ratio of PWM
modulation signal.
Cutting Frequency
Set the carrier frequency of PWM modulation signal during cutting,
i.e., the laser number within one second. The larger the value is, the
more continuous the laser.
Cut focus
The position of focus far from Sharp-tongued of cutting head nozzle.
Piercing time
Delay for piercing plate, so make cutting more fully.
Laser off delay
Delay for ensuring complete cutting before laser off.
The definition of piercing parameters, such as pressure and power and so on are similar to
the cutting parameters, which can take effect only when the option of “2 stages” in ③ is
selected.
Piercing speed
Set the speed from piercing height slow down to the cutting height
