PMMA CNC Cracking
Sorun Belirtisi
PMMA sheet edges chip during CNC machining
Neden Analizi
Dull tools or excessive feed cause cutting forces that chip and crack brittle PMMA edges; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting
Çözüm
Use sharp single-edge tools; adapt feed speed; support the sheet bottom with a backing plate; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Temel Çıkarım
PMMA machining edge chipping is controlled by tools and process; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
