CAN U POST A SCRERENSHOT OF WHERE IT IS?

You should likely set the Control Definition for Inverse Time feed rates for the rotary movements. You will need to increase the min inverse feed rate in the Machine Definition as well.

Your file has it set set to degrees/min for the 4th axis rotary feed.

You can try using a barrier cream. It might help prevent the reaction.

In your Control Definition under Tool there is a check box "Enable Staged Routines". This is to turn on or off staging the next tool.

Without a file it is hard to make suggestions. 

Have you tried just drilling one hole and doing a transform rotate operation for the remaining holes? 

IMHO you will never hit that tolerance with hardened D2 over that large of an area.

Deboer isn't listing any end mills for hardened steels that I can see.

What material is it? Like @Jobnt said this is a tall task for a part of that size!!!!!!

What machine and what kind of holders are you using?

What end mill brand are you using?

Union Tool makes specific tools for machining hardened materials. 

There is no simulation for lathe.

I want to cut out a cavity of this model out of a basic rectangle stock. 

I created a video for you showing how to create a cavity from a solid model.

Techsmith is no longer I guess

We have a Snagit license here at work, that is Techsmith.

Thank you again for the great help!!!

Glad to help!

I am constantly learning from others here!

@berntd See this video I made of your file.

Build in a half-hour "meeting" to hang out with some good coffee or other motivating thing every week or two,

This is an example of continuous improvement.....have time for everyone to input ideas/ suggestions.

Silence speaks volumes here.

You might find it easier to start with wire frame chaining. Create a Curve on the top edge of the hole you want to cut. Do this on a new level. Then turn off your solid.

Solid chaining works well but  you need to make sure the selection is correct as @AHarrison1 stated above. 

Your file shows each toolpath with 1 solid chain selected, this looks correct.

Work on using Levels to separate your geometry. Move your solid body to a new level and name that level "Solid Model". Then move all your surfaces to a new level and name it "Surfaces". Then if you need any wire frame geometry put that on another level and name it "Wire frame Geometry". This way you can turn on and off the other levels making your geometry chain selection easier. 

Make sure you are in the “Right Gview plane” then select Transform rotate.

Or use Dynamic transform.

Create a standard for levels such as doing them in intervals of 10. Possibly having fixtures on a dedicated level in all files if possible. Have a dedicated level for Notes on the part/ job and programming so anyone that opens the file can view these. 

Implement the use of View Sheets to easily pick views and or levels.

If there isn’t anything currently in use create a logical file storage structure system for storing and accessing files. Try to have all files for each part or job contained in the same folder whenever possible. Have a revision naming policy so everyone follows the same process.

Develop a verification process that everyone will follow when G-Code is created. 

Insist on having comments added in every tool path. 
 

I have HSM Advisor for speeds and feeds. We use a lot of Helical Solutions/ Harvey tools, their machining advisor is excellent.

Two significant firsts in my life back in the 80's were such crap I will never buy them again. One was a Harley Davidson motorcycle and the other was a Hewlett Packard computer.

You forgot to add GibbsCam to that list!!!

You say everything correctly, but I don't have a machine and I don't have the task to go through all the stages, I would like to start by understanding the creation of a machine with similar kinematics in Mastercam, so that at least everything works correctly in Mastercam, if I haven't figured out at this stage where I'm going to the postprocessor to the machine, but I want to figure it out while it doesn't work out on my own, so I'm turning to the community / colleagues, I hope they will respond here or on other forums...

Without a valid Ziptogo file no one will touch this since it reeks of piracy IMHO.

how it should be implemented in Mastercam

The Machsim is more or less just bling unless you have a kinematic aware post processor from Postability or In-House Solutions. Then you have to license the Module Works module for the full Machsim.

Having a tested Post Processor, a matching Machine Definition and Control Definition (these are not part of your Machsim file) are the first steps in Mastercam. The post processor translates the NCI file that Mastercam creates in the background into G-Code for the specific Machine/ Control. The Machsim that you can build and or comes with Mastercam is only verifying the NCI code not the actual G-Code that the machine will interpret. This is why there is a need for verification software such as Vericut or Camplete.

I can show you files that verify fine in Mastercam and on a Machsim but in Vericut it shows the collision as it is verifying the actual G-Code.
