Tolerance Stack Up Analysis Step 3
Step 3 shows you how to handle clearances in complex tolerance chains and tolerance stacks.
See the guide for Step 3 as a video below
Which tolerance stack path should you chose?
• When analyzing your mechanical design, it can be challenging to identify the correct path
• In this example, there are two possible paths
• Using RD8's Pathfinder tool will display these two paths
• This creates a risk of conflicting paths - sometimes one path controls, other times the second does.
• Such uncertainty adds no value to the product and can lead to design issues
How To Fix Your Tolerance Stack
• This problem occurs because the design is over-constrained
• Adjust your design so it is not over-constrained
• When the design is fixed with only one controlling path, it becomes possible to make the design robust.
• The first image shows an over-constrained design, while the second does not
• The second image demonstrates a design with a single path, which can then be made robust
