Motion Design

The motion-design can be easy or very difficult. It can be very difficult when many axes must interact.

It is always important to try to improve the motion-design when you need to improve the performance of a machine.

First Steps

There are a number of steps to design a motion. You must:

1.Write a Motion-Specification that satisfies the positional, velocity, acceleration and even jerk requirements for each machine-axis in the machine.

2.Write the motion specification of each motion-axis as a function of the Master Machine Angle. Each motion-axis has a tool that interacts with the packaging or product - for example a 'pusher'.

3.As necessary, split the motion into a number of segments - this is called Segmentation.

Each segment can define a particular action - such as 'Push', or 'Lift', followed by 'Return', etc.

The segments are joined together, end-to-end, so that they describe the motion of a tool over one complete machine cycle.

4.Begin to define the duration of each segment making some shorter and others longer. The total duration remains as 360°.

5.Select a Motion-Law for each segment. The Motion-Law must be able to meet the motion-values as defined in the motion-specification at the start and end of the segment.

6.Edit the motion-values at the start and or end of each segment - using the Blend-Point Editor and Segment Editor - to fully satisfy the motion requirements.

7.Complete the motion design for all of the axes on a machine.
