Lathe program

[Metals and materials]

I am very new to making lathe program. I have to program a hemisphere for production, turn an ID.  Here is the picture. SO far, I was able to program a bit. But it feels like the program is not good enough. Axis/spindle combination is lower and left. If anyone could help me that would be awesome. I am attaching file as well. 

Issues I am facing is all the time, there comes the warning that my tool is embedded in stock. If I change rough direction, it won't work at all. 

Here is the file.

I made  a few changes to get closer to the end result. I don't have 2023 loaded so I cannot send it back.

The tool geo for T0303 will have to change to something that has more clearance on the back angle, this is where all the collisions are coming from.

Only when it gets closer to the drill point.

I drove the drill deeper to remove more material.

Changed Stock Recognition to Remaining Stock in op2 to stop the tool from starting past center

Changed lead in for op2 to feed into cut

As mentioned earlier, the tool geometry for op2 needs more clearance at the back

 

Hope this gets you in the right direction.

Greetings,

In the attachment you will find your part with some changes.

This can only use you as reference if you want better program we should talk about tools, mat and so on.

So what I did is:

Drilling with D52 tool to the max depth
Opening the hole with normal ID turning (much faster)
Removing center with Face grooving tool and doing final pass with the same tool

This is my solution for your product at the moment

Also you can check how I did set up and so on.

Speeds and feeds aren't correct so please do not use them,. Once again it's just an reference so you can see how it can be done.

I hope this can guide you on the right path

Also be careful  with the things which @AHarrison1 said in earlier message.

Kind regards.

Ivan.

...yeah so my intention was not to do the work for him, but point out why he/she/it was getting the errors and collisions

and as you stated

...not lead, guide.

If he/she is new to the lathe programming 

one example program won't hurt at all

Still this program wont work well (won't say why), because at one pont you smash your inserts over and over again

 

Some people needs example to find the right path.

To others you can just give small hint and they will figure it out what to do.

This is much helpful. You both showed me a good path and example. It's a good guidance. @AHarrison1 @BehindYou Let me work on this now. 

Just a small recap of what I will be doing. 

drill deeper, change stock recognition, change lead in, change tool. 

after drilling, open with normal ID turning and remove center with grooving tool. Finish with grooving tool as well. 

Let me try this. Will mess around parameters to find what's happening.
