How to convince management to invest in post-processor

Hi

I am facing a problem, our management isn't convinced that is necessary to buy or order a new post-processor for our new machines which cost less than 1% of the total price of each machine.

CAM provider does have the required experiences to deliver for us a suitable post-processor.

So based on the above, is this logical in manufacturing to accept buying a very advanced machine but refusing to invest in post

How do you deal with that usually, do you build your post in-house? or do you get help from your CAM provider if yes, how much does that cost you?


Thank you.

If you have someone onboard with experience in writing a post for this CAM that is easy.
If not depends on if a generic will work but tiny problems can be big headaches and scrap, hand edits which are expensive.
Hand fixes are bad, someone will screw that up given enough programs and time.
Doing your own post in house may mean a learning cure. That costs real money too although many do not book that.
No idea how many hours spent on a Mcam post but I did it off hours so no cost.
Do you really need a custom post?

Add up all the time it takes to manually edit a program to get it to run in a machine and multiply that times the amount of programs you write a year and give them a dollar value. Most owners just need to see a dollar sign.

Which CAM software are you using and which machine/control is it?

Don’t worry about it. Tell them if your going to be stupid you got to be tough.

Are you a software engineer? Do you know how to write the post processor? If yes its fine.

If not it is very challenging for a complex machine tool. 10/10 would not recommend unless you know how. Editing a post processor? That is a different story and I can do that. Nothing crazy though.

You wouldnt forget to buy toolholders for a new machine would you?

How much would a bad crash cost?

THIS!

+ "management" obviously do not understand what a post is, or they wouldn't be querying your need.
If this is multi-ax (and it probably is), i wouldn't go the home grown route. I'd do my homework and buy a known working one from the post writer.
Explain to "management" that it's way cheaper to do that, than you running back and forth to your reseller with mods and the HUGE amount of time it takes....including the fact that the more complicated/features the machine has, you may not see an issue until way further in the future. Because you maynot have gotten around to be using that feature yet...

A post for that machine can't be too expensive, can it?
I would guess around $2k?
Do they offer a generic post where you can alter it?

I know Mastercam has a bunch of generic free posts (non 5axis) where they are meant to be altered to suit your machine.

Damn.
I'd be putting my 2 weeks notice in if I worked for a company that narrow minded and frugal.

what he said, if they're cheaping out on a 2k post processor, they're gonna cheap out on a ton of other shit. get the fuck out of there asap.

Shop I was working at 15+ years ago bought a fancy new machine, biggest and most expensive they ever had. Had a high dollar repeat job lined up for it, with expensive stock blanks and a lot of time in each part, (cut, flip, cut, stress relieve, cut, flip, cut). I practically begged them to get Vericut or the like, but they refused. I then advocated for careful planning of the process, but the boss ordered us to take the shortest path to starting to make chips, so that's what we did.

First batch of parts came back from stress relief, we did the finish cuts, and found a small gouge that was made during the roughing. Boss said "How could this possibly happen?!" I replied "You didn't get what we needed do to the job right."
