Weak point analysis

Machine tools, handling robots and other manufacturing machines must meet certain rigidity requirements. Only in this way can the required production quality be met.

With complex assemblies, the question often arises as to which components have the greatest influence on the overall compliance at a given point.

We answer this question by FE-simulation of different expansion stages of the assembly.

Using a classic milling machine as an example, these expansion stages could look like this:

• milling spindle
• milling spindle + quill
• milling spindle + quill + sleds
• milling spindle + quill + sleds + moving stand
• milling spindle + quill + sleds + moving stand + Machine bed (complete machine)

At the end of the calculation, a diagram is created showing the compliance of the individual expansion stages. The largest jumps in the diagram indicate weak points in the assembly. With this knowledge you can optimize your products in a targeted manner. You save time in design, avoid prototype costs or damaging warranty claims.
