When you say Horz arc on lead in/off you mean this page and put 0 to turn off? I don't see an off...

Thanks guys for the honest feed back on this... I think I am going to start with a new post and go from there... Here is a picture of the gouge ... The You-Ji's have Fanuc 18i-TB and Oi-TC controls...

Hello, Lately I have been having bad issues with surface high speed .. I have scrapped three parts now ($20,000).. The more and more I look into the gouging issues the more and more I find that most people I talk to have stop using this because of these issues.. Why? Here are my settings .. The crash never comes up in backplot or verify.. We don't have Vericut or G code software .. But I sent the NC code to a friend who had Vericut and couldn't find it... How many people here have these issues? How many people here use high speed surface toolpaths? The main programmer here at one of the places I program for told me that there Mastercam dealer told him to only use old school flow line if you don't want to gouge part... I can send the nc code or file for people to test or look at.. I like the surface high speed because it makes programming easier.. I don't have to make 1000 separate surfaces for every feature so old school flow line will work.. Also I was told not to use solids for geometry that surfaces are safer... Is this all true? My boss wants to change to another cam software or program the old way with flow line.... I can't scrap another part here.. The crashes have been on a You-Ji VTL lathe with live tooling and Niigata horizontal machine.. The post are 8 to 10 years old.. But I was told this isn't the issue... Thanks

That is what we do already... They do thousands of programs here every year and most are all just cut a paste and hand write the code. I ask why do we have Mastercam then.. That is the one problem /question and it is why they brought me in here.. For instance when a program needs a rev change or something more.. and you go back to the 5 year old Mastercam program it really show you nothing about how the original MC code was produced... So what I am trying to do is to have manual entry's and text file linked to Mastercam so when they do post it is all there for the most part.. Most of the stuff is special drill stop go cycles and z depth moves on special arcs at certain points.. And sub programs with only certain code.. Things that are really hard for Mastercam to do in the post so that is where text files and manual entry come in... At least they are in the Mastercam operation tree... I spent 3 days trying to figure out how they did one program from 4 years ago because the guy who did was gone... It was just add z moves at a certain point on the arcs in many places... It would have been easy to make a manual entry or text file for this.... Even a note in the operation tree would work... Posts are there biggest issues because the ones they are using now are 5 to 10 years old or older.. They have over 20 different types of machine that is a huge $ problem for posts... So I am working to get this fixed.. I have most posts ready but need to test... Thanks

Hi, Where in this post is the text output code controlled? I want to remove some lines that it posts when I use a text file for code.. Basically I want it to only post what is in the text... I know I can just put the code in the manual entry area but what about when it is longer then 750 characters and then I want to use text file. Where... or can I change this in the post... ? We have X6 W7.. This is what it post like now... N10 G91 G28 Z0. M05 < -------------------- This line needs to be gone ----------------------> N20 G28 X0. Y0.

Tried those setting same thing.. If I use old school surface contour it looks fine but the code is huge and take for ever... I would think I could use the new high speed stuff...

It is definitely the finishing 1/2 ball endmill... I just ran that tool only and it has some gouging..

Hi, I have this part that I am using surface high speed waterline to rough and finish it... I wanted to use opticore to rough but it was taking way to long to regenerate.. I left it for 2 hours and it was still going... We have a $5000 HP Z800 pc... I am getting what looks like gouging with the finish 1/2 ball endmill waterline .015 step downs... I see it on the verify (Look at pics). Is there a setting that I need to change? It is running on a horizontal Niigata.. The material is Graphite.. You can see what the part looks like after the lathe on one pic...

When you say gouge setting you mean here? In the gap setting?

Great thanks those worked... I was trying to use surface high speed tool paths..

Great thanks that tool should work.. But the problem is to get Mastercam to work with that tool... I have had no luck yet.. It just acts like the under cut part is straight 90....

Hi, Is there a way to use a full radius slotting mill to surface this part? It has a under cut radius.. Or would it have to be 5 axis or 4 axis positioning to make this? The part is small only 1 1/4" long and the radius are .020 and 1 mm.... I know I can have a special form tool made but it is $500 and they don't want to spend that...

Perfect thanks...

I live in Portland Oregon area and high end programmers can make $35 to $45... I have been in manufacturing since I was 10 in my dads shop.. The problem today is everyone just wants to program and use cad/cam and make as much as possible sitting at a desk... Companies are finding out that you can be the best Mastercam and other Cad/Cam programmer and not understand how to correctly make the part or hold the part.. Maximum material removal comes to mind it is lost in most new programmers and machinists today.. I get paid very well and I mostly just teach new programmers and machinists about how make and hold the parts.. And make the Cam system work like the shop wants... In the next 10 to 20 years manual machinist are going to be very hard to come by and will be a dyeing trade.. One of the companies I contract program for has the manual machinists making the most money out of all CNC operators and programmers.. Every new programmer and machinist should learn how to run a old worn out manual lathe and old manual mill and understand things like climb and conventional cutting and understanding and feeling how it cuts.. I was so surprised at how many new programmer's and so call machinists didn't know the difference between climb and conventional cutting...

Hi, I have a older horizontal post for a Niigata machine. I know where the use pitch for taping is on the MPmaster posts but how or is it controlled on these older posts? Can it be added to these older posts? Or is it best to start over with MPmaster? We have X6..

Thanks.. In the misc values great.. How hard would it be to add this to a old post? Probably be better just to make my MPmaster post work with my Niigata's..

You know how to fix this with the MPmaster post?

Ok thanks.. I am finding out from other sources that these older MPfan posts are a lot harder to fix this issue then the MPmaster... I might start over and use MPmaster...

Hi, We have a Niigata horizontal mill.. When we use transform translate or even on any B move it will post a new WCS (G54).. I though this was controlled in the transform translate page.. But not matter what I change to it still posts a new WSC for each B move... Where can I change this? is this control def or post controlled?

Thanks again Colin you have been very helpful... That worked perfect.. You wouldn't happen to know how to change the R in a canned cycle to post R.0 always? The VTL's use a weird canned cycle where the R can't be bigger or the same as the Z before it.. So they just put a R.0 and it works every time...

I just found out the Q needs to be Q1000 not Q .1... Where do I change this at? Thanks

Hi, We have a You-Ji vertical lathe and for some reason all of it's canned cycles G83, G81 and so on use a incremental R value.. So the R has to be smaller then the Z retract height before it.. But they said the R can be 0 and it will work fine and it just read the Z retract before it... So basically I just need to change the post to always post 0 on the R values with all canned cycles... Where in the post do I change this...? This is how it post now.. N1 M01(17/32 DRILL) G00 G18 G40 G80 ( DRILLS WITH 17/32 DRILL ) G00 T1010 M06 M69 M22 M41 M66 G00 G54 X9. Z.1 C90.
