ASDA-A3 Motion Control
E-Cam curve
In the E-Cam curve for the rotary shear system, apart from the requirement that the cutter cuts
at the right position, it is important that the master axis and slave axis run at the same speed,
which means the relative speed is zero, so the the materials are not over-stretched when
7
cutting. In terms of cutters, wider cutters require larger synchronous speed zone (as shown in
Figure 7.3.7.3). The proportion of this zone is determined by the cutting length instead of the
cutter width, as shown in Figure 7.3.7.4.
