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
Arrow head position depends on profile width (Autoflow and Microline only) |
