There are two types of rigid tapping on a lathe. The first is on center line of the main spindle using a static tool holder. This type requires the rigid tapping option to be turned on. The second is rigid tapping with a live tool, which is usally stadard on a live tool lathe. By the looks of the alarm the machine is generating, you are running main spindle rigid tapping code. Is this a live tool lathe?

Yep. 0.0015" we've seen this issue from the old SL-3's up to the NZ-2000's

I've worked with Mori-seiki lathes for 20 years, and found this to be common with all models. We predicted this condition to the point in which we would offset the x axis in the negative direction by 0.0015" after returning from lunch and make adjustments untill the machine warmed back up. Once warm, the machines are extremly accurate. Hopes this helps.

Hey guys, faily new member here. I thought I would share. We have a dilema! We have (2) Mori-Seiki NZ2000 T2Y2 on order, along with a NT3200. We are wondering how we are going to drive these monsters(It gets better). We currently use 4 different software packages to get the job done. Fanuc capt for lathes, Master cam for live tool lathes, part maker for swiss lathes, and cimatron for our mills. Why we have accumualated all these different packages is beyond me, evolution along with personal preference I guess. We are being asked by management to get on the same page, and pick one package everyone can use. (easier said than done) Any way, I called our Master Cam re-seller and asked them if master cam was working on the mill/turn support. They also told me that X3 would support the mill/turn. (Multi-tasking, as they referred to) due out in April. Any Suggestions on our current library on Cam packages to choose from?

Sorry Guys, I failed to metion that we are going to use WTO adjustable angled rotary Tool. Rodney J

Hope this is an easy one for all the veterans. We have a project which involves drilling (4)45 degree holes in the face of a part. We have a Mori-Seiki NL-2500Y Lathe to acomplish this feat on. Not real tuff to write this path long hand. We would like to simply create the point geometry and the tool path with mastercam. Has anyone had to do anything special with the machine definition to accomplish this. Any help would be greatly appreciated. Rodney J

What brand name of grooving tool are you using? We do alot of small parts, and found that P.H horn tools do well. Rodney J.
