Are you proving out the program while filming? kind of curious what is happening that the mill spindle keeps skipping or executing more segmented movement during simultaneous machining. Figured you have you hand on feed-hold and sort of pushing the machine through the cut gradually while running through the program. Also looks like DMG CTX / NTX? would love to see more videos and perhaps some reviews. I have some experience running Mazak Integrex machines so would be cool to learn more.
Hello in this case I just had one shot here. Unfortunately I didn’t had the right settings for the five axis movement in MasterCAM. If they are right the movement will be smooth. Even when you have the hand on the wheel to slow down when it gets scary 🤣 I stated also in a Mazak I200 the most time i spend on a Mori NT4250 now CTX1250 Each great machines in they’re segment. Thanks for the great feedback 👍
Hello the most CAM softwares have conventional Prime Turning included like MasterCAM, GibbsCAM, ESPRITCAM etc. there is also an code generator called (tool path) which you can order at the Sandvik homepage. If you want to use the y-axis there is just Gibbs for these tools so far.
Even a old CNC from 1999 can do it but not with the controller supplied back then. You can retrofit a CAM package tho for a lot less money then buying a new machine.
This strategy looks like it has the potential to greatly increase tool life because the corners of the tool would be used equally and for only half of the cutting time. Compared to an ever-widening right-to-left strategy where one corner may take a majority of the wear. I suppose it depends on workpeice rigidity. Eager to try this, what do the internet machinists think?
depends on the part, material, depth of groove, width of insert,... some materials don't form chips so easily, some will form thick strings that will jam in the groove, causing overheat of the insert, also i wouldn't groove stainless or similar materials this way since the resistance could cause the ring to vibrate bit too much and break the insert, also this way the sides if the insert are in constant contact with sides of the groove, causing friction which means heat, also the bottom diameter of the groove holds "the rest" of the unsupported workpiece, means that if you do one groove that ends on small diameter and then continue second that is on the unsupported side of the part, things may get nasty really fast
Then you get a small entering angle, hence thinner chip, way smaller than the feed value. That’s why you can apply huge feed per revolution like 1,5 mm/r, depending on depth of cut. It is like milling with round inserts with small depth but higher feed. Cheers
Hello It depends on the machine of course. But I found that the b-axis is more stable with heavy turning than the turret in some cases. You have good eyes my friend the tool on the turret has a wiper radius so therefore the surface is better. Feed rates are totally the same on both tools. Maybe because the camera sits on the turret it appears maybe a bit different Cheers
