Drive functions
A rotating motion becomes an oscillating motion. You shape the motion profile directly in the diagram, segment by segment.

Two mechanisms coupled by a roller follower
A roller follower couples a four-bar linkage and a one-bar linkage. The example shows how ASOMmini derives the cam curve from both motions.

The task
One curve from two motions
A four-bar linkage and a one-bar linkage are given, together with their motion sequences. A roller follower on the coupler of the four-bar linkage connects the two mechanisms. The task is to find the curve it describes relative to the one-bar linkage. Due to the relative motion, this curve can become quite complex and cannot always be used as a cam plate without modification.
What ASOMmini shows here
- You specify the drive functions, and from them ASOMmini draws the curve of the follower relative to the one-bar linkage.
- ASOMmini draws both possible curves of the follower – one for each contact point of the roller.
- Change a drive function or move a bearing, and the curve changes along with it immediately.
Your benefits
Derive cam curves from the motion
As early as the conceptual design stage, you see how every specification affects the shape of the curve.
No curves by hand
You do not have to construct the contour point by point – it results from the motion. More on analysis
Assess feasibility early
You see early on whether the curve becomes too complex to be used directly as a cam plate.
Reuse
You export the curves as a list of points in text format.

Chebyshev straight-line linkage
A Chebyshev four-bar linkage guides a point along an almost straight line. ASOMmini shows how straight: with a coupler length of 20 cm, the straight section lies within a corridor of about 1 mm.
