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
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
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

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)
If a cad program can save you half an hour of work per day, it will be paid in less than a year...
I will never understand some managing who tries to cut on software, they are the key to get a rentable shop....
I have a lot of "blank" parts just to save time, so all the parts who are similar are programmed with the same method, its a lot easier for the setup man on the floor
