What are the types of speeds in which the engraving machine acceleration is adjusted?

The types of speeds in which the engraving machine acceleration is adjusted include the take-off speed, the spindle speed, the turning speed and the acceleration setting.

How to adjust the acceleration of the engraving machine?

Open the genuine engraving control system and enter the manufacturer parameters - input password - plus, take-off speed, uniaxial acceleration - turning acceleration - jerk:

1. Engraving machine take-off speed: This parameter corresponds to the take-off frequency of the drive motor. The so-called take-off frequency is the highest frequency at which the drive motor can start work without acceleration. Reasonable selection of this parameter can improve the processing efficiency, and can avoid the low-speed resonance of the stepper motor with poor motion characteristics; but if the parameter is selected large, it will cause the brake to be stuck, so it is necessary to leave a margin. . In the factory parameters of the motor, the take-off frequency parameter is generally included.

However, after the machine tool is assembled, the value may change due to the quality of the assembly, and it is generally reduced, especially when doing load motion machining. Therefore, the setting parameter is preferably determined after referring to the factory parameters of the motor.

2, engraving machine uniaxial acceleration: used to describe the acceleration and deceleration of a single feed axis, the unit is mm / sec square.

This indicator is determined by the physical characteristics of the embossing machine, such as the mass of the moving part, the torque of the feed motor, the resistance, the cutting load, and so on. The larger the value, the smaller the time spent during acceleration and deceleration during exercise and the higher the efficiency. Usually, during the setup process, start setting a small amount, run for a period of time, repeat various typical movements, pay attention to observation, and if there is no abnormal situation, then gradually increase the value. If an abnormal condition is found, lower the value and leave a 50%~100% insurance margin.

3, engraving machine turning acceleration: used to describe the acceleration and deceleration ability of multiple feed axes linkage, the unit is mm / sec

Square. It determines the maximum speed of the woodworking engraving machine when doing circular motion. The larger the value, the greater the maximum allowable speed of the woodworking engraving machine when doing circular motion. Usually, for a machine composed of a stepper motor system, the value is between 400 and 800, and for a servo motor system, it can be set between 600 and 1000. If it is a heavy machine, the value is smaller. In the setting process, start setting small, run for a period of time, repeat the various typical linkage movements, pay attention to observe the condition of the engraving machine, and if there is no abnormal situation, then gradually increase the height. If an abnormal condition is found, lower the value and leave a 50%~120% insurance margin.

4, engraving machine jerk: used to describe the acceleration of a single feed axis, the unit is mm / sec square.

Such as the mass of the moving part, the torque of the feed motor, the resistance, the cutting load, etc. are accelerated. The larger the value, the smaller the time spent during acceleration and deceleration during exercise and the higher the efficiency. Usually, during the setting process, the default setting is started and run for a period of time. After the running-in period, the stepping motor can be adjusted to between 2000-25000, and the servo motor can be adjusted to between 25000-40000, which is an important value affecting the speed.

How does the acceleration of the engraving machine increase the influence of the spindle speed?

1. Increasing the spindle speed will result in more heat of cutting: the heat of cutting has a very large influence on the service life of the tool. Why does each material have a reasonable cutting line speed? It is to limit the generation of cutting heat.

2, increase the spindle speed can reduce the amount of knife per revolution per tooth: the amount of knife per revolution per tooth = feed rate / (spindle speed * number of teeth), reduce the amount of knife per tooth per revolution can reduce the cutting force To make the processing smooth.

3. Increasing the spindle speed can increase the output power of the spindle motor: It can be seen from the power curve of our spindle motor that the higher the speed, the greater the output power, and the smoother the processing.

In general, it is beneficial to have a higher spindle speed, but at a reasonable speed range because it is the most important factor in tool life.
