9.4.2.4 Electronic Cam Data for Cutting Thick Material
In above rotary cut application, there is only one contact point for the cutter and the material, regardless
of the thickness of the material. In this way, only one synchronizing point is required when designing the
electronic cam. For thick material cutting, such as soap or steel plate, the velocity relationship between
cutter dropping and the material moving should be considered. When the material enters the sync area,
the material moving speed will equal to the moving speed of cutter, ensuring that the cutting plane is flat
and vertical to the conveyor. The below diagram illustrates the operation angles between the cutter the
material. V1 is the material moving speed; V2 is the cutter dropping speed; and the grey curves indicate
sync area (cutting area). When the thickness of material is equal, the contact angle between the cutter
and the material (angle θ) is a fixed value. In addition, the cutting angle α varies during the cutting
process. The velocity relationship can be described by the equation below:

According to the diagram below, the cutter rolls through non-sync area and syn area. In sync area, the
horizontal moving distance (L) of the cutter should be the same as the moving distance of the material,
and the horizontal moving distance can be obtained by the equation:
