Chapter 7 Motion Control Programming Home V Equal to the speed of the master axis Distance for which the master axis moves (Length of a cutting) 2. During the processing of cutting materials, synchronization is an important factor. When the bladed of a rotary cutter come into contact with a material, the speed of the blade must be the same as the speed of the material. If the speed of the blade of a rotary cutter is greater than the speed of a material when it comes into contact with the material, the force which pulls the material forward will appear, and the material will be cut smoothly.
If the speed of the blade of a rotary cutter is less than the speed of a material when it comes into contact with the material, the material will be jammed. 3. The design of a synchronization zone affects the operation of equipment. The bigger the synchronization zone is in a cycle, the less time it takes for the slave axis specified to accelerate/decelerate. If equipment needs to accelerate/decelerate in a short time, there will be a great impact on the electric machinery used and the blade used, and there will be an overcurrent passing through the servo used. 4.

After the cutting roller used leaves the synchronization zone, the cutting roller will accelerate.
