External Factors that can affect accuracy on Stuga Machines

Sommaire

Back To General Accuracy Guidelines


There are many external factors that can affect the accuracy of Stuga machines. it is incredibly important that these factors are all eliminated as potential root causes.

If you do suspect that one of these factors is potentially a problem, it is equally important to be able to prove and demonstrate your suspicions clearly.

External Factor Description Common Symptoms Link to Page Affected Machines
Temperature change Profiles expand around 0.5-1.0mm per 10 degree in temperature change

If the bar temperature changes between machining and sawing, the bar expands and accuracy is compromised

Operation position randomly out Proving temperature change variance Flowlines

Profile Width Depth of front V and Y notches depends on the profile width

Depth of V notch incorrect on one profile only All

Incorrect link data (Y notch codes) Machine will cut to the depth that it is told Y notch depth correct before welding, incorrect after
