ASDA-A3

 Create E-Cam curves without synchronous speed zone

This kind of E-Cam curve is only suitable for applications using pointed cutters and can only be

created by ASDA-Soft. The setting interface is shown in Figure 7.3.7.8. The specification

settings for the rotary shear are as follows:

1. Gear teeth ratio: set the gear teeth number of the motor (A) and gear teeth number of the

cutter (B).

2. Number of cutters (C): set the cutter number based on the rotary shear mechanism.

3. Cutter diameter (d1): set the cutter diameter based on the rotary shear mechanism.

The cutter radius is the distance from the cutter shaft center to the cutter end; the cutter

diameter is two times of the cutter radius. This value does not change with the cutter

number and the software will calculate the circumference drawn by the cutter end.

4. Encoder diameter (d2) and encoder pulse number (N): set the diameter and pulse per

encoder revolution. The command resolution can be calculated with these two values.

If you know the master axis’ gear ratio, entering the encoder diameter and pulse number

are not required. You can simply input the values for P5.083 and P5.084.

5. PUU number per motor revolution: set the PUU number per motor revolution (slave axis)

after E-Gear ratio conversion (P1.044 / P1.045).

6. Cutting length (L): set the material cutting length. To avoid generating an unsuitable rotary

shear curve, the software automatically limits the cutting length by referring to the ratio (R)

of the cutting length (L) and the arc length between cutter ends (a); R = L / a; R = 0.3 - 3.
