  Cut speed	The actual cutting target speed.
  Peak power	Adjust the laser through the analog quantity to set the laser intensity during cutting.
  Cut frequency	When cutting the carrier frequency of the PWM modulation signal is also the number of times the light is emitted within one second. The larger the value, the more continuous the light is emitted.

       Caution

       The speed power curve is an incremental curve, and the added values need to be increased sequentially and 0 and 100 cannot be modified.

     • Select a group of speed and power values, and click Delete to delete this group of values.

       The left curve box synchronously adds or deletes the corresponding nodes.

   To restore the curve to the default curve, click Clear.

During machining, the system will automatically adjust the speed and power/frequency matching relationship according to this curve, without other manual operations.

Lead Line Technics

Used to select the lead method and set lead parameters.

1. Select the lead method, the lead method is described as follows:

   Lead Method	Description
   Lead line technic	Since the lead fall slowly lifts the height of the pierce, parameters such as the power of the lead need to be increased accordingly to ensure that the pierce can penetrate.
   Fall slowly	In the initial stage, the slow speed leads to high energy, and the large amount of slag can easily cause jitter with the movement. The influence of slag on the capacitance can be reduced by raising the cutting head to the height of the lead.
   Circle	In order to remove the area with excessive slag, but it is not necessary to consider the cutting effect.

2. According to the selected lead method, set the corresponding parameters. The parameters are described as follows:

   Parameter	Description
   Cut speed	The actual cutting target speed.
   Peak power	Adjust the laser through the analog quantity, set the peak current during technic cutting, and correspond to the peak power during technic cutting.
   Cut frequency	The carrier frequency of the PWM modulation signal during technic cutting, that is, the number of times the light is emitted within one second.
   Duty cycle	The duty cycle of technic cutting.
   Lead line height	The position where the Z-axis starts to fall slowly.
   Stable distance	▪ The distance for lead line cutting at cutting height. Calculation formula: stable distance = lead length - fall slowly distance. ▪ When the set value is greater than the length of the lead line. Calculation formula: stable distance = lead length - 3mm.
   Speed	The cutting speed of the lead circle.

Accurate Machining

Set the slowly start and stop technics.

Parameter	Description
Enabled slowly start	Used when poor cutting occurs during the initial stage of thick plate cutting. If fine adjustment is not enabled, the effect is equivalent to the original slow start.
Enabled slowly stop	Used when dragging the end stage of thick plate cutting elements. If fine adjustment is not enabled, the effect is equivalent to the original speed.
Sharp corner	Used when the corners of the primitives are sharp and easy to burn. Peak power, frequency, duty cycle used to cut sharp corners in and out for a short distance. ▪ Angle: The maximum angle of a sharp corner between line and line/line and arc/arc and arc. ▪ Length: The length of the sharp corner deceleration section and the length of the sharp corner acceleration section (refer to the length of a single end, not the sum of lengths).
Arc corner	It is used when the corner of the primitive is an arc and there is dross. For primitives whose curvature radius is less than or equal to the set radius in the graphic, the peak power, duty cycle and frequency can be set independently.
Accurate cutting	It is used when high power machine thin plate cutting (when the auxiliary gas is high pressure gas such as nitrogen and air) corners hang slag.

Finely adjust the technic at the start and end of cutting to improve problems such as burn through, impermeable cut or over burned slag.

Caution

The slowly start and stop technic conflicts with the following three machining technics.

• During fly cutting and high-speed micro-joint, the slowly start and stop technic does not take effect.
• When lead fall slowly takes effect, slowly start technic does not take effect.
• When the slowly start and stop technic is in effect, the speed power regulation is not in effect.

Counterbore

Through the counterbore technic function, the section effect of the precious metal can be guaranteed, and the counterbore can be directly machined to avoid drilling and chamfering.

This technic is only supported in large graphics/medium graphics/small graphics/L1/L2/L3 layers, not in marking and global parameter layers.
