Login with my Xometry account Tolerance stack up question
F
Hi all, I’m new to the world of tolerance stack up and working on a snap-fit assembly with five injection-molded ABS components. In prototypes I’m encountering inconsistent engagement forces, likely due to tolerance accumulation across mating features. How can I use GD&T or tolerance analysis software to identify and control critical variations? Are there any beginner-friendly best practices or tools you’d recommend to ensure consistent performance?
