How to avoid cutting machine cutting thin plate Angle at burr

In the use of the process of cutting machine for cutting stainless steel, using air or nitrogen gas, auxiliary gas at the end of the machining Angle of shape or material can produce a burr on the back. This is what reason is caused?

rate is set by NC cutting machine cutting head movement, but in the mobile end of shaft Angle of conversion or processing, processing speed is influenced by cutting machine features and slow down. In general, cutting equipment power set is fixed, so the processing speed slow down the location of the place, can damage the balance of power and speed, Excess output power) , lead to burr. So how to solve this problem? Basically has the following three methods:

1. General machining conditions

on the set of processing conditions, try to reduce the cutting speed of cutter, to reduce the difference between the cutting speed of the entire process track. Cutting speed in both large and small, the output power is to set the corresponding as burrs with less quantity. Using the downside of this approach is that the average speed decreases, the whole processing time.

2。 Modified trajectory

ultra range trajectory design, make the cutting speed is not reduce at the end of the Angle department or department. For example, to do the programming for at sharp corners circular overtravel processing program. When did ring processing, trajectory in the processing direction transformation, will become a process of gradual change, to avoid the sharp decline in cutting speed. End USES annular distance, hole processing order, which can also be the condition of lower cutting speed incised the inner hole. But when the Angle near a product, or Angle of the medial and lateral are products, not allowed to use this method.

3。 NC control

according to the above problem, has developed the corresponding control function. Namely, through the real-time detection of metal cutting machine cutting speed and output power with cutting speed change automatically adjust to the appropriate value of the function. When the cutting speed at sharp corners to slow down, the output power also reduced accordingly. At the end of the process is the same, the output power will decrease as the cutting speed reduction and automatic.
