Hello
thank you for entering in my post
I'm running this cnc milling
As you can see on my picture we have this raised jig, I asked to my manager and also to an engineering of my shift about this 245mm platform to raise this jig and nobody could give me a good reason why they made this platform
From the lowest operation to Z limit minus (as you can see on the picture) we have 250mm so we don't need that 245mm platform, perhaps we need it only 10mm or 20mm higher just to be sure that the angle head reach the lowest operation
How close we could work to Z limit minus?
If I can take this platform out we may ruduce the operation by 2 tools.
As you can see on the top of the engine case we have a sump rail that is the very top part and the cap-face that is that bottom in the middle of the case (signed in black). We are doing the roughing-out and finishing with 4 tools to reach the cap-face because otherwise we get Z limit plus if we use the same tools as for roughing-out and finishing, but if we take the platform out we could use only 2 tools.
The finished depth between the sumprail and the cap-face is 210mm so if we use the same tools with their enough lenght of 220mm, (in addition I don't understand why they made these 2 tools 250mm long) we should be able to do this 2 operations, roughing-out and finisching cap-face, with only 2 tools
Do you like my idea? Are you agree with me that that platform is an engineering manufacturing mistakes?
Any suggestion according it will be very appreciated
thank you in advance for your helpLast edited by hoezap; 28-07-2012 at 02:12 AM.
