4.7.4. Introduction to the Cam with Rotary Cut Function

The function curve of the cam with rotary cut function could be divided into sync area and adjustment area.

Sync area: Feed axis and rotary axis make the motion at a fixed ratio (Linear speed of knife is usually equal

to that of the cut surface), and material cutting takes place in sync area.

Adjustment area: Due to different cutting length, position need be adjusted accordingly. Adjustment area can

be in the following three situations based on various cutting length.

 Short material cutting

When cutting length is less than the knife roller circumference, the rotary cut curve for any cycle is shown

below.

For the cutting of the short material, rotary cut axis must accelerate first in adjustment area, and then

decelerate to the synchronous speed.

 Equal length cutting

When the cutting length is equal to knife roller circumference, the rotary cut curve for any cycle is shown

below.
