Servo Tube Cutting Basics: Why Length Tolerance Matters
Servo tube-cutting tolerance has a direct impact on fort assembly fit and should be controlled as a daily core process.
In toy fort PP tube sets, unstable cut length can cause frame looseness and uneven corner stress. Servo cutting with routine blade checks helps keep assembly fit and repeatability in control.
Tolerance Strategy For Assembly Fit
In fort tube systems, unstable cut length leads to uneven node stress and visible frame skew after assembly.
Set tolerance bands by tube role and validate insertion-force consistency during first-piece checks.
Daily Control And Preventive Maintenance
Blade wear, feed drift, and sensor offset should be checked by shift to avoid silent drift in length output.
A short first-piece and last-piece comparison record gives quick evidence for line stability before lot release.
Servo Cutting SOP Checklist
1. Define tolerance band by tube function role.
2. Run shift-based blade and sensor checks.
3. Archive first-piece and last-piece comparison records.
