The steps for creating a cam are explained by means of a sample application that describes a rotary table with eight slots (45° division). Inside, there is a component that is fused ultrasonically. The welding tool is fed in by a linear drive after the rotary table has turned. After welding, the linear axis returns and the rotary table continues turning.
Work steps
Rotary table turns 45° (duration: 400 ms)
The welding head is moved down by a vertical axis of 250 mm (duration: 200 ms).
Start welding (duration: 1200 ms).
The welding head is moved up by a vertical axis of 250 mm (duration: 200 ms).
A cycle time of 2000 ms results from total times.
The application is implemented by means of a virtual mas that runs continuously (modulo). The end value of the axis is projected according to the cycle time of 2000 ms. The rotary table is achieved as a cam (modulo; end value: 45°). The vertical axis is also achieved as a cam (restricted; end value: 300 mm). The welding process is controlled by a tappet.
