4th axis help

[bhayden10]

Good Morning,

I was hoping someone would be able to help me get started in the right direction on programming this part. I have only been to school for the basics so far and I havn't had the chance to do any true 4th axis milling or worked with surfaces very much. I put it in the mcx folder, its called auger. I've tried several different ways but not getting the right results so far and really not sure what the best process would be. My reseller is busy until this afternoon and I was hoping I could get a head start on figuring this out. I have a 4th axis haas vf6.

Thanks

here is an idea if your looking...on the ftp site called augerjpn.mcx...you can change the cutter or stepover to what you want

i have updated this with a curve and a flowline toolpath and hopefully that will help

I would jump in and try, however my company is too cheap to maintain so it will have to be posted in MR1 of V9 for me to open.

I appreciate your input! I am looking at it now and learning what I was and wasn't doing right.

This looks like a lead/lag job. You have to modify the normals on all surfaces (they face inwards). Use 5-axis flowline, with lead/lag, and the 4-axis option. The bead (the auger flight) will gouge on one side with the lead/lag, so you would have to split the surfaces, and do half rotating CW, and the other half CCW. The conical surface would have to be remade. First untrim the bead and fillets. Create edge curves of the UNTRIMMED fillets. Unroll them. Square up the ends so they have the same Y and roll them up again. This is so the 'rulings' are in the X direction. Split the surface and machine it. I'll send a part if I get it done first.

yes i had to change the normals on the surface for a flowline and it worked well...+1000 on splitting the surface on the screw itself...would never have thought of that...thanks John!!

Thanks for the help guys. I'll be waiting to see how you ended up doing it. I would never have been able to do what John is talking about on my own. I appreciate the help!
