Figure 2.32 Enter Values of Rotary Shear Specifications
Gear Ratio: Directly enter the number of gear and the system will figure out the gear
ratio automatically.
Cutter number (Knife No.) and diameter (Knife Diameter d1): The cutter number can be
changed according to the application and should be equally allocated on the cutter
axis.“Cutter radius” is the distance from cam center to cutter tip, cutter radius times two
is “Cutter diameter”. Therefore, regardless the cutter number, cutter diameter is always
the same. See Figure 2.33. ASDA-Soft will figure out the cutter circumference from the
cutter diameter.
Figure 2.33 The Relationship between Cutter Number and Cutter Diameter
Encoder diameter (d2) and pulse number (Encoder Pulse): Encoder pulse is the pulse
number being sent when encoder rotates one cycle. As encoder diameter and pulse
number are known, the resolution of the command of the master axis can be figured
out, which is the value of P5-84 (when P5-38 = 1). In this case, if pulse number of the
master axis (P5-84) is known, there is no need to enter encoder diameter and encoder
pulse number. Users can directly enter the value of P5-84.
Motor PUU No. per rev.: It is the required PUU when the motor operates one cycle and
converted from E-gear ratio.
Cut length (L): the cutting length of the material, which can be changed by users.
When using the software to create a rotary shear curve, to avoid creating an inappropriate
curve, the software will automatically generate a creatable range based on the ratio of
cutting range and cutter circumference. For example, if cutting length A is much shorter than
