# Troubleshooting Plastic CNC Routing Issues
January 09, 2023
Is your [finished plastic part](https://industrialcustom.com/product-development-services/) not what you expected? When trimming and edges look funky or are too jagged, the root cause is often an issue in the [CNC routing process](https://industrialcustom.com/plastic-routing/).
Luckily, these issues can be avoided – if you know what to look for.
## The Two Most Common Plastic CNC Routing Issues
### Problem: Ugly Cut Edges
### Cause: Worn Tooling
Dull cutting tools create a lot of heat and cannot properly eject chips of plastic, causing them to melt on the cut path. This is the number one problem we see, and it’s also the easiest to fix – it’s time to sharpen your tools or replace them if they’re too worn.
### Problem: Inconsistent Trimming
### Cause: CNC Fixturing
There are two critical factors of fixturing that ensure consistent, repeatable trimming: sufficient fit and vacuum zoning. If the part geometry differs from fixture geometry, the part will not sit on the fixture the same way every time, and the vacuum might not seal properly.
Aside from having a good seal, the vacuum zones need to hold the part in places where part rigidity is lacking.
