1. Set the power to 65%-70%  
Set the minimum power and maximum power because the speed of cutting a straight line is faster than the speed of cutting a corner. We said that the faster the speed, the shallower the cut.  Therefore, in order to cut through the sample, we usually set the minimum power and maximum power.  
2. Set the speed to slow
We all know that the faster the speed, means the higher the processing efficiency, so we will increase the power to improve the speed as far as possible when cutting general materials, but acrylic is different, too fast speed will make the section is not smooth, concave and convex, so in order to cut a smooth effect.  We need to keep in mind when setting parameters: increase power, reduce speed.  
3. Do not blow when cutting  
Appear a lot of people when cutting acrylic, cut white, that's because he used a blow when cutting, so if you want to cut out the effect of smooth, please turn off the air, at the same time also want to remind you, when not blow cut acrylic, please must be in the guardian, because without the strong blowing flame retardant, in the process of cutting material is easy to fire,  If fire is found, please turn off the machine in time.  
4. Overhead cutting  
When cutting acrylic, if you want to avoid the melting edge problem caused by the reflection of the honeycomb plate, we can use overhead cutting to solve the problem.
