What kind of machine?

Are you seeing rotation collisions that won't really be there?

If your simulation isn't tied to your post, simulation is "sketchy" at best, it misses things....one thing I have is my post gives me clearance moves automatically at rotation and offset changes for my HMC's...becasue I do this in the post, I get crashes that I know are not going to happen....what I am really using the simualtion for is checking clearances between holder, fixtures and parts.....I set my retract value to a large number and run simulation...once I know the clearances I am checking for are good, I set my clearance back to 1" and post.

Not sure if you're seeing something similar.

Review the collisions to see what's actually being reported.

I dunno, I have a 5 axis post from Postability that handles this perfectly without the need of using different tools...

I honestly think you're solution is either getting IHS to address your post issue or garnering a different post...

If that's a purchased post, check with the post writer...they're generally good on support to get the end users output

I think he wants it to cancel g68 , index ,and re issue 68 without a tool change

If that's the case, yeah, post edit all the way

I just opened a SW 2019 file in MC 2020 with no issues. Maybe some setting. Perhaps try something different in Options before opening sldprt in Mastercam?

I tried merging a couple yesterday, then I tried opening them...nothing happened...

I downloaded the files in stp instead, opened fine....this happened to me after installing Update 3.1

If you are using an operation that has a force tool change within a transform, yes, you get all the forced tool changes to post out...

But what you're trying to actually get is still a little unclear to me

Find out if the machine can use pitch....then the feed is      1/no. of threads

1/4-20 would be .050 on the feed

3/8-16 would be .0625 on the feed

Then just set a speed

So its just the simulator ? Nothing wrong with my programming?

Nope...I'll usually post to verify, just to be safe

When programming tombstones I will sometimes make sure same OP faces are not opposite so I can get through Machsim

What sizes?

Generally run our taps at 2k+ RPM when rigid tapping...it's never gets there though

Hello All,

I just want to add my 2 cents here, We also would love to get wear compensation on 3D toolpaths.  Very often we need to add the entry and exit motion manually to get it done.  I know what Jayson is saying but if you look at it, changing the 2D comp will have a very very small effect on the 3D point of contact of the tool on the surface.   This would be very helpful for us when machining large cone shape chamfers or machining angled walls.  The abillity to have or not wear comp would be a huge plus for us.

 

Let us have the option please!

In all reality though, most machines don't support it.....I had a case just this morning, I posted a path with comp but it was a 3D contour and when the control read the G19 it alarmed out...had to remove the comp on/off lines

So what did you want to see different to colors?

The colors pallet, in the Global setup in Cimco provides a good idea....different motions, different colors......makes it easy to visually see what's happening

Folks please share with us what you want to see in Code Expert that help make that your default.

Colors

Backplot ability, ala NCPLOT

Ability to understand machine canned cycles

Ability to understand work offset positions

Ability to deal with Fanuc macros

That would be a good start

Typical regular anodize, doesn't change but a very little.....0001/.0002, if that much.....hard coat, that's a different story...

I have seen threads come back from anodize a mess because of crud that gets into the holes....I have only chased those by hand with cutting taps...

Chansing hardcoat is going to be problematic....typical build-up is .0005/.0007" per surface, that quadrupled on threads...you can find thicker calls of anodize...determined really by time in tank

eia and FTW!!!!

Sounds like it was never saved...

Have you tried saving your file before posting?

Love them....used with the honed inserts, a freer cutting you won't find.

The only thing I use Code Expert for is, Mill/Turn, don't have a choice about that....

all code and post editing I use Cimco

Backplot NCPlot

And it is free!

Not any more

Hey Metallic,, what is this X+?

Something you have to pay for now starting in 2020...so if you're not already using it....and unless willing to pay for it, I wouldn't bother

i see a lot of people use wear, might be a dumb question but what if using a certain size end mill then run out of them and have to switch to a different size?

ive been using control. im guessing this is just for mill also?

what about lathe?

No regrinds here....we may use a different length but don't change programmed sizes

Perhaps its the type of work we do, but that's all way beyond me.  I would like to do some things to reduce setup time here.  However for now its just a matter of indicating fixtures, edge finders, etc. 

It was for me at one time as well 

the other option is do like above, bring in people to get it done...it really does pay for itself.

Hell, the first program I made, I had to explain how the G10 line worked, because up until then, they just hoped and prayed they didn't overwrite an offset in use!!!

We're in the process of moving to a lot of hard fixtures, Raptor, 5th Axis and such....

While importing the G10's, at first there was skepticism that it would be close enough....we did discover that when machining fixtures, we would get the greatest variance. That was directly related to stack ups' not meeting the models...with the hard fixtures, the G10 numbers for X & Z have been spot on....the Y we were chasing but that was related to how it was being references at the machine.....my post has been modified to calculate from the table now and everything going forward will come out that way, giving us a much greater accuracy...

I am trying to get the total setup down at the machine....that's my ultimate weapon for chasing a CAV package.....

This was not accomplished in a day but it's been a constant improvement.... 

To my way of thinking, I'm asking why isn't it done already?

When I started where I am now in 15', they had HMC & VMC posts that required a fair bit of editing after post and had nothing extra for functionality in them...they did have some active reports setup sheets, mostly ironed out but still in need of some minor help...no tool libraries, no holder libraries, no machine sim, nothing else...

While I am the only one of 3 programmers here that programs all equipment, VMC, HMC, Mill/Turns & 5 axis, the most focus I end up is on production HMC work...20 spindles alone. about 40 spindles total and move on the way.

1st thing I did was dial in the HMC post to be edit free....as time allowed, I then did the VMC post, again edit free....tool libraries were next....creating specific tools on the fly and saving them into a common library, it really didn't take long before I had a library teeming with defined tooling....holders were next.....from there, tweaking the setup docs.....then finally the machine models and machsim...(we still need a CAV package though, machsim does have some limitations)

All of this has made my job easier, it has made it not only more reliable but more consistent as well...make no mistake about it, the setup guys appreciate that...I provide to them complete tool lists, p/n's included, tool assembly information, include holder, tool and stick out values, complete G10 offset output into the code...

The time that I have saved by utilizing all that was made available is huge....people are thrilled with how fast a complete job can set turned around from the programming office to the floor...in most cases their experience before all of this was weeks to now in many cases days....

Yes, defining everything single thing that you can, so that it is used over and over and over is nothing but a time savings...

:shrug:

What does the posted code look like?

Backplot can be weird with 5 axis paths and not always completely accurate
