@Elvincnc There is some challenges with sending Lathe toolpaths into Machine Simulation, but we are able to simulate turning on the FD style mill with turning table. Here is an example of a DMU Duoblock FD I have.

I have written several dozen of them over the years. Most of the ones I've developed were "mechanical kinematics", where the machine does not use Dynamic Codes. The Dynamic Codes allow you to adjust the machine to track the Rotary and Tilt axes, zero points, and offsets. For a "purely mechanical" 5-Axis Post, I can set one up in about 20 minutes, and they usually require 1-2 days of back-and-forth testing, or less. But the problem is: these posts rely heavily on being able to take precise measurements at the machine. And you must move your geometry in Mastercam, relative to the "center of rotation" on the actual machine. In other words, you must completely configure your virtual world, to match your physical world. That means you must actually measure at the machine, any time your physical geometry is not oriented perfectly at the machine, and you must repost your NC Program for any changes at the machine. Or, alternatively, you must take the time to "dial in your part perfectly" at the machine, and any error in the setup is translated into errors on the part as you move and rotate the tool and/or part in 5-Axis. I've written several 5-Axis Posts that support Dynamic Codes, and to do this right can take days or weeks of effort, depending on exactly what support is required. Dynamic Work Offset, Tool Center Point Control, and Tilted Work Plane, are the "heavy lifting". Now, couple all the Dynamic Code support, with adding Inverse Kinematics (for driving Machine Simulation from Post Processor output), and you are talking a ton of development time, unless you've already developed a "framework" (like In-House Solutions has done with their IKE Posts), for supporting all these codes. Now, throw all of that development and architecture away, and start over with MP.NET, from the ground up...

Sorry, I just have to revisit this statement again. This is basically the guy admitting that many Resellers don't have the Post Development and Debugging skills, in-house, with developers employed by the Reseller. Any competent Mastercam Post Developer, should be able to fix anyone's code, unless they have truly gone "off the rails", but I've only ever seen a couple of instances of that happening. It is true that if you completely hack up all the logic, and "break" the architecture through bad coding (or refusing to listen to good advice and reason), that even a competent Post developer would say no. But that is really much more the exception, rather than the rule. (And sounds to me like a sales scare tactic. "These things are really complicated, and you might break it, so better to just let our dealership change your oil for $120 bucks, rather than you doing it yourself. If you put the wrong oil in, your car might blow up! ) I've got 42 videos on MP Post Development, which are part of my MP 101 Basic Post Processing class. All those videos are available for free, and I promise if you watch them, you will at least learn enough to know "where your skills are at, and what you should attempt to code yourself, versus leaving to the professionals". I'll let you all in on a little secret. I don't develop 5-Axis Posts for customers. Not because I'm not capable, but because of the amount of focused work required. I basically draw the line at 4X Mill and Lathe Posts, and anything more complex I'll use In-House Solutions. If a customer is already using Postability, then that is fine too. In the interest of full disclosure, one of the reasons I love In-House so much is because of their willingness to help machine tool distributors (like Phillips) with Post Support. We can request a Post for just about any machine and configuration, and get a working copy for my Applications Engineers very quickly. Often, in the same day as the request is made. We also get direct support from them when we go onsite for training, in case we discover any Post issues while onsite. Could I build those 5-Axis Posts? Absolutely, given a clear statement of work, and enough time. But my job involves so many things now of which "Post Development" is just a small piece, I'd rather leave the heavy lifting to the professionals. Plus, I have to support and engage with multiple CAM software platforms, including my new favorite. (Can't name it on here, since that is against the rules, which I respect. Hint: it is two letters, and can do a whole lot more than "just CAM").

@JrScottI will agree with @Jake Lthat consistency across all posts does have a fair amount of advantages, and might be the best decision for many users. That being said, I am also very much against the "that's just how we've always done it" rational for decision making, so hopefully I can help to further inform your decision. @SuperHoneyBadger did an excellent job of outlining some of the advantages we have worked hard to build into the IKE posts. I will expand on a few points, I could go on and on, but I will try my best to keep it brief. We have developed our post generate machine simulation to mirror the motion that will occur on each line of code, as it is generated. Where this is specifically advantageous is with approaches and plane transitions, where we are able to simulate advanced controller functions like TCP and Tiled Planes. I made this video a couple years ago when these changes were introduced to show off what was now possible if your interested. Machine Simulation Improvements With Your IKE Post - YouTube Our axis sub has been written to allow support for any machine configuration. It will run on any 5-axis configuration with a rotary table. I have even been able to post and simulate axis substitution on 6-axis machines with very little modification. Having the rotary table perform the rotations, while the universal head is fixed, but with the option to fix that universal head at infinite positions with the tool horizontal. Similar to the machine in this video, but using axis sub instead of simultaneous. Post | Feed | LinkedIn We have a very large number of post switches available for customization, and our posts have been designed with flexibility in mind. Most customizations we do see, are already built into the post on a switch, but we are very much capable of customizing the posts as needed. We also are continually adding more switches and features into the post engine. Despite all the great features available in the IKE posts, I think our biggest asset of IKE is the team behind it. We have a large and experienced team that is ready to customize your machine for your specific needs. We will continue to work with you until you are completely satisfied with your post, and do out best to ensure you have a positive experience throughout. If you want to check out IKE for yourself, we have FREE IKE posts for 3/4-axis Fanuc and Haas mill available to download at this link. Free Post Processors - In-House Solutions (inhousesolutions.com)
