GENERAL TOLERANCES IN THE FOUNDRY
Differences admissibles in mm for Dimensions in mm
The average general tolerances applied are TF 15 for the DIECASTING and TF 18 for SANDCASTING
Some particularly fine tolerances can be exceptionally obteined on certain dimensions
Unless otherwise specified, the remainders are counted in addition to the primary casting with the following values:
- minimal ..1% - 30' - normal .....2% - 1° - emphasized 5% - 3°
AMOUNT OF CLEARANCE (mm) ON FACE ACCORDING TO ANGLE AND LENGTH
These values are important as they modify to (+) or (-) the forms of pieces
