Oh Geeze... I better back up the truck. Wire Vs. Sinker... in the job shop.
I think these guys have covered most of the major points. EDM machines are great, but they can be expensive and a pain in the ass to keep going if you don't really need one. I would also lean towards a wire before a sink, there's really not a lot of crossover in the capabilities Ime. One more...- 007Rob

Solidworks: extruded cut but not normal to the sketch plane?
If I'm understanding correctly, you should be able to create a plane on the 45 degree axis. If you use that plane to create your sketch you should be able to drive the cut normal to that with all the normal options/features -

Reaching correct dimensions when not roughing with full wire width.
Depending on the precision needed, and other factors I've dealt with this a few different ways. Sometimes I will just run the first roughing pass twice, since the first pass without the wire buried leaves extra material running the pass a second time will reduce the amount leftover. I have...- 007Rob

Easily grind on a CNC using electroplated wheels
Can you show any examples of some grinding jobs done this way in a VMC? I have run into jobs where it could be a good solution, but the uncertainty factor has usually pushed us to go other directions.- 007Rob

3d probing on machine
We tested software from Hexagon a while back which uses this concept. You pick the measurement points on a 3d model, then the software will first calibrate those vectors on a calibration sphere before measuring the points on the part. It seemed to have a lot of potential, we did run into some...- 007Rob

Tracking spindle hours - NGC
I'm trying to track the spindle run time on some of our machines. We have a few different machines on the next gen control. On the settings page you can get the info on run time since the machine was powered up, but nothing for the actual spindle hours over the life of the machine. I found one... -

Drilled hole repeatability issue
Are you using a spot that matches the tip angle of your drill? I'm wondering if your drill is walking a bit when it engages the material which could create the inconsistency.- 007Rob

Advice on annular cutter for 3" hole please
I would probably just use a hole saw if it's only .750" thick in 1018 -

Machine brands and thier controls
No, they are not all like that. Ok I would recommend familiarizing yourself with the controls of any machine tool before you try to operate it. -

Mori Shakes Aggressively
Are you sure it's a mechanical issue? I've run a high speed Mikron before where if you had a program with a tight tolerance and short point to point moves, the acceleration/decelerations were so aggressive at full rapid it would shake the sheetmetal and it sounded horrible. The solution was...- 007Rob

SolidCAM hangs up at Generating G-Code or Simulating
I use Solidcam but haven't run into this particular issue. Do you have your temp folder setup on your local computer? We had it setup on the network before and it would cause weird issues when the connection would drop out from time to time. Another thing I have run into in the past with... -

WIRE physical location
Agreed I've never really heard of contaminated water being an issue, but for maximum precision temperature control can be a factor. As well as there are a lot of control boards inside a wire machine, so if it's an older machine and the shop gets really hot you could see an increase in part...- 007Rob

Effects of shallow cut while trouble shooting
What is a "threader"? It sounds like you are talking about deflection. Because of the extra material on a roughing pass, the tool can get pushed away from the material a little bit. So if you re-run it again without changing anything it can still remove some material even at the same offset...- 007Rob
