Suspected Sources of Variations (SSV's) | Tool for pinpointing | Technical solutions |
|---|---|---|
Poor hole preparation | VS | Change hole production method |
Poor machinability of material being reamed | VS | Change reamer material ; try cobalt containing HSS or carbide |
Poor machinability of material being threaded | VS | Adjust operating parameters and chaser geometry to suit material being threaded |
Poor machinability of material being threaded | VS | Using chasers with roughing and finishing throat often helps |
