Observations : Nota 1 : la cote repère S est hors tolérance, pour information la cote se situe à l'entrée d'un des 4 trous Ø4.
Nota 2 : suite a vos remarques nous avons effectué une mesure de rugosité dans la zone elliptique cote repère AN qui s'avère être hors tolérance. Cette valeur est simplement due au pas d'usinage, par conséquent en réduisant le pas par 2 ou 3 la rugosité serait conforme. Pour information l'outil utilisé dans cette zone est identique a celui des zones 1 et 2 ou nous obtenons une rugosité de 0.007 à 0.008.

CONTROL - fitting tool to maintain the part without deforming it - minimum of contact to avoid to mark the part - use of the super ACC ZEISS machine to get the precision
MACHINING - fitting tool to get the 1µm flatness - setting of the tool (diameter, radius, position in X and Y) - milling strategy to get the best roughness possible - feedrate, cutting speed - good speed to obtain the good following of the axis
COMMENTS
We know now that it is feasable in the precision asked but it has required : - a lot of developments to get the precision and the roughness required - a lot of time to machine the standard part
Any change in the design implies changes in the process and development of the manufacturing
MACHINING OF A COMPLETE STRUCTURE
PROBLEMATIC - the aim is to manage to produce parts according to the drawings in a limited time - It implies to have a reliable processDIFFICULTIES - It is necessary to reduce the number of operations at the minimum - It will be necessary to monitor the tool wear for a complete structure - The design of the milling has changed. The radius at the bottom decreased from 3,15 mm to 0,5 mm, thus the type of milling tool is different.The milling strategy has to be reviewed to get the good roughness Example : the path of milling to mill the cross should be divided by 2,5 to get the same roughness
STATE OF PROGRESS
- The milling operation is validated in term of roughness- The turning operations are validated- The flatness in milling and turning is validated
-We are in a process of validation of the exact position of the milling tool (X, Y) This is the last point to be able to launch the machining of a complete part.
