...and it's working like a charm

Why just .3 deep? i'd go full dept, 12% stepover .05 step up first of all, try to get a variable pitch endmill, they are way much stable, and perform better than a regular 4 flutes, yes they cost more but the payback will be in time and problems savings you can start around 1500-2000 RPM AS much coolant as possible feed + or - 80ipm All theese are for a good rigid machine and setup

basically the same thing from a different foundry

Exact i want to avoid typing the setup sheet name each time

I'm glad that I've found this topic , anybody find a way to change the default "save as" name, now it's the machine description, i need i to be "NCFILE/OPERATION/TOOLPATH-GROUP-NAME" ? TIA it's nearly 2AM here, I'm pretty sure it's an easy fix but i did not find it...

It's achievable via C-Axis but the speed is limited to your machine ability to handle really high feedrates at high precision with C-Axis engaged tweek the machine by ptogram it with a C-axis face contour toolpath and turn on the ramp option just install a normal tool in the turret and tweek the tool offset, you may need to find a way to override the C-axis connection limit switch in the PLC IMHO at the end, an offset jig is WAY more reliable and easier

Ca fonctionne avec un axe "C" je l'ai déja fait sur un tour Okuma utilise le toolpath circ mill avec un ramp équivalent a ton avance normal et chaine le diametre voulu ca demande un peu de gymnastique mentale mais ca fonctionne

That's what i usually do , but in Mazatrol and IGF you can control the overlapping feederate in the system parameter I have the answer from IHS, Mastercam cannot change it because this movement don't have it's own flag An enhancement request has been ask by IHS, hope to have it done in the next 15 years Thanks

My parts are generally between 36in and 70in diameter its the same ratio as you but on a larger scale

no matter how much stock i leave the problem is the tool geometry FYI between 0.010 and 0.050 depends on the part

I'm calling the Lathe gurus here, I want to know if someone find a way to increase overlapping feed rate in lathe's Roughing cycle with small passes at high RPM it doesn't makes a big difference but with .750 DOC at 25 RPM it's looooooooonnnnnnnnngggggg for now i turn overlapping off and make a semi-finish pass but the tool suffer in vertical walls TIA Martin

I did a lot of buttress threads on an old Okuma Cadet, I've always get good result with straight infeed and the exact shaped ISO insert (SECO) in the G71 line set "B" at "0" then M32 M75 will be your cutting infeed pattern if the cuts are too rough change the M75 by M74, it will decrease the DOC (and be longer to run too)

Buttress threads

a good old Niagara SR420 solid carbide rougher is the way to go slow feed slow RPM a lot of coolant and they can take a huge cut in inconel

I had the same issue, but it seems fixed since the last Nvidia Quadro driver update *crossed fingers*
