Josh K. Posted October 1, 2014 Report Share Posted October 1, 2014 I have no idea what it is. We call it a light house.... We used a "Harvey Tool" T-Slot cutter. Quote Link to comment
Mattndew76 Posted October 1, 2014 Report Share Posted October 1, 2014 I have a couple Harvey carbide T-slot mills. Decent price and quality. Quote Link to comment

Josh K. Posted October 30, 2014 Report Share Posted October 30, 2014 Fun part I made today. Stock was 6" dia x 8.25". Finish wall thickness was 0.074".... 2 Quote Link to comment
mklotz70 Posted October 30, 2014 Author Report Share Posted October 30, 2014 Wow!!! Was the center diameter interpolated or bored? Quote Link to comment
Josh K. Posted October 30, 2014 Report Share Posted October 30, 2014 Bored. It's 8" deep, 3.468" dia, +/-0.001" concentricity of 0.002" the full length. I beleive this is the easiest of the 4 part numbers. One is +/-0.0005". Fun stuff. I'll post them as I go... 1 Quote Link to comment
q-tip Posted October 30, 2014 Report Share Posted October 30, 2014 Well that's a nifty part Quote Link to comment
datrod Posted October 30, 2014 Report Share Posted October 30, 2014 That's some cool shit Josh.. Quote Link to comment
q-tip Posted October 30, 2014 Report Share Posted October 30, 2014 I wish taking pictures of the garbage I work on wasn't a federal offense or I could show you guys some of the big stuff. Its funny really, one of the parts I make for the military is itar controlled yet I've seen it on the discovery channel but if I have a picture of it I'm done. 1 Quote Link to comment
]2eDeYe Posted October 30, 2014 Report Share Posted October 30, 2014 Take a picture of the discovery channel :D Quote Link to comment
q-tip Posted October 30, 2014 Report Share Posted October 30, 2014 I don't remember what show it was, it was actually the military channel, it was something about subs or nuclear powered things, and it was also about 5 years ago. 1 Quote Link to comment

mklotz70 Posted November 10, 2014 Author Report Share Posted November 10, 2014 Very cool! Did you do multiple setups or 4th axis to get the injectors ports? Quote Link to comment
captaingamez Posted November 10, 2014 Report Share Posted November 10, 2014 That is very nicely machined! Im with Mklotz, Did you do that with 4th axis? Quote Link to comment

captaingamez Posted November 11, 2014 Report Share Posted November 11, 2014 Rotary. jealous... lol Quote Link to comment
Mattndew76 Posted November 11, 2014 Report Share Posted November 11, 2014 wish it was a rotary that I could rotate and machine on simultaneous . Quote Link to comment
mklotz70 Posted November 11, 2014 Author Report Share Posted November 11, 2014 Is it still considered 4 axis if it's not simultaneous? Since your rotary doesn't do simultaneous, it's like having a really convenient 2nd setup? Do you have to switch work offsets once the rotary is repositioned? The limitation is do to the machine control's abilities? If it was a round tube you were working on, you could just use the rotary as the Y axis and do it simultaneously.......correct?

q-tip Posted November 11, 2014 Report Share Posted November 11, 2014 With the machines we have it retains the offsets when the b axis rotates to its desired angle. But we also set out z offsets from the center of the b axis. Its all in how you program it. Edit: we have hbms* 1 Quote Link to comment
mklotz70 Posted November 11, 2014 Author Report Share Posted November 11, 2014 Okay.....so it will reposition and keep going without any manual intervention. Still beats the heck out of having to mount to another fixture! :) Quote Link to comment

Edit: we have hbms* Okay.....so it will reposition and keep going without any manual intervention. Still beats the heck out of having to mount to another fixture! :) When programming in multiaxis (4+) situations, it is always easier to program from a central point. Meaning, the intersecting point of all axis datums. For example, we program a setup on a 4th axis tombstone where there is only one offset, that offset is the central point of the rotary axis, the central point of the z axis and the central point of the x and y axis. Programming this way allows us to simultaniously machine 4 different parts at the same time, all with multiple compound angles that can not be done in less than 3 operations on a 3 axis. Or for example a set of parts that requires two pieces and each needs an op1 and op2, meaning 4 setups would normally be required to make them. This way, I set the machine up one time, on one offset, and it makes all 4 parts all day long until we have enough. It stops every 2 hours to allow us to remove complete parts, rotate ops1 to ops2, and put in new raw stock. All this also has to be programmed with backlash, meaning that before going to any rotary position point, the rotary axis stops, or goes to -30* prior to that position in the offset. This ensures that it goes to exact position, as opposed to just directly going to that position from any direction. Quote Link to comment

Edit: we have hbms* Mike I use solid model representations in the programming stage too so I can see if any crashing may occur during part rotation. All off of one CPL. 1 Quote Link to comment
