Normally this is a function that's tied to Ctrl + Mouse wheel. Are you sure your control key isn't stuck?

Sorry, all of this info was for Opti-Rough I thought this was what you were using. I have never used Area Roughing. Looking at the 'Help' parameters page it looks like the "Add Cuts" button just below stepdown does something similar to what I was describing above. Like I said though, I don't really know this toolpath.

I have seen this happen for a couple of different reasons. Mostly settings that might be hard to understand. 1. Skip pockets smaller than. (This is mentioned above.) This setting takes into account stock so you have to be careful with that. 2. Helix Radii. It's important to note that this is radial and does not include half the tool size. Typing in .250" with a .500" tool will generate a hole in the part 1.00" in diameter. 3. Steep/Shallow settings. 4. Not using Stepup. This is the setting that gets me almost every time I have this problem. Stepdown looks down until it violates a floor, then it deletes that last step. Meaning if you're within .950" of the floor and step down is set to 1" it will not cut the last section because it's less then the stepdown value. The best way I have found to negate this is to turn on stepup and set it to the same value as the stepdown, meaning it will look both up and down for material getting rid of that last bit of material. Hope this helps, Caleb

Kevin, the issue with the G68.2 may be the code following it. The post I'm using for an Integrex is not setup properly and posts code on the K line that is past 360 degrees occasionally, looking something like this. G54 M108 M212 B10. C20. M107 G68.2 P1 X0. Y0. Z0. I0. J10. K380. G53.1 P1 G97 S2139 M3 G43 H#3020 X-.6858 Y.0534 Z.0764 This throws the machine into a similar alarm state. In your example I can see that you're using A-90. however your I is a positive value. Maybe try switching this either to a negative value or possibly 270 degrees. The moves it makes during this mode can be extremely dangerous, approach this with caution. With Regards, Caleb

Colton, I took a quick look at this. It seems to me that it's the way MC is interpreting the diameter of the tool vs the angle. I got rid of the taper angle in the path and it works fine. With an endmill it's using actual diameter (of shank) which is .375" (hence the .007" overcut you're using in the first path, because the cutting edge doesn't extend all the way to the shank) Where with the thread mill it's better taking into account the taper of the tool, using the tip size instead of shank size. I hope this helps. Caleb

Like this? Limits.zip I'm using a conical limit switch down the center of the part with the setting of the upper and lower limit at 9.405 so it locks the B axis and C is still allowed to move.

I don't happen to use blade expert. Perhaps somebody who does will chime in.

If you're trying to define an oval form tool this is a Barrel form tool in Mastercam. Mastercam has a 2019 and 2018 description of all of the Emuge tools that are available. I've attached the 2019 version. If you need to make a different one I would suggest using one of the predefined tools and editing it to suit. Emuge-circle-segment_inch_2019.tooldb

Arc Filter/Tolerance. you could just set Minimum arc radius really high and it would turn them all into linear lines.

I've seen this confusion quite a bit in forums over rest material with the tool starting inside. There is a special rule that isn't clearly defined when you use Optirest. The boundary chain must be used, and the strategy is locked to inside. All you have to do is select the compensate to, Outside and type in value that at least exceed your tool size. Edit: If you're an official Mastercam user on the website you can go to Univeristy.Mastercam.com,Mastercam Webinars 2017, Stock Model and Opti-Rough Webinar. It goes over in detail the problems you're seeing.

What are you doing with the RAH? Just drilling... or milling too?

There is a much better editor IMO. Sublime Test 2. It's a tool for programming in other languages, but has some tools that significantly help with edits. It has a little bit steeper learning curve then CIMCO. But, It is free and has more flexibility. Some of the key things it has is multiple cursor, fuzzy searching, regular expressions, and better multi program sync. It was recommended to me by a Mazak engineer and I don't think I will ever go back to any of the other editors.

As gcode said, there is not default hotkey. There is an additional button that does the same thing in the bottom right hand corner. I occasionally click on these by accident. Perhaps that was it?...

Here is how you get sharp corners into that part. Like what was said, this is going to require a minimum of four axis. For-Ecam.mcam

Clamping and unclamping is not for locking out rotaries. This function is for full 5x programs. As default the machine is in a clamped state. If you command a rotary move the rotary unclamps, moves to the designated position, and reclamps. If you wanted to make a full 5x cut this would be a problem as the machine would unclamp and clamp on every line with a rotary move in it. So, to create smooth 5x motion unclamping the table until you're done with 5x, then reclamping is what is required. Do not try to use this as a lockout system! It is not what it is intended to be used for.

OptiRough does this sometimes because of stock. If you stock turned on it uses -Stay Inside only andeverything is then controlled by the containment boundary.

...and higher rollover rates. Here is what that means. https://en.wikipedia.org/wiki/Rollover_(key) You can also bind macros to particular key strokes, which can be beneficial. Plus, they light up... who doesn't like something shiny?

I use a logitech G502 and love it. I really prefer the corded mice over bluetooth as the slight delay messes with me sometimes. I use a combination of claw grip and palm grip depending on how long I'm programming. For anyone who doesn't know what I'm talking about here is a link to the description of the different grip styles. I keep my mouse around 4000 DPI which is fairly fast. Standard button layout for me. I'm using this on a steel series mouse pad, highly recommend this. Fairly cheap and extremely smooth action. Once the mouse is calibrated to it the input is a lot more predictable. https://www.epicgear.com/en/technologies/types-of-mouse-grip As a side note my keyboard is a Corsair Strafe MX Cherry Red. The mechanical keys plus high rollover rates really help with Mastercam when only using the left hand on the board and some strange key combos that don't come up on regular keyboards. Plus the mechanical input guarantees input everytime. Really a must have for me.

The easiest way to do this is to just type in fields below this column what you want. To actually change that that section you need to change your configuration file to imperial. Then it will open the imperial taps file. A much easier way to do this is to go to the standalone tool manager and change that to imperial, as this won't try to adjust everything else to imperial, such as, geometry and other things on screen.

I also have one, but it just sits unused. I prefer my gaming mouse and keyboard setup. I have the same exact setup at my house, on which I play video games. So my setup makes sense for me as hand positions and feel remain the same.

Is this just a C axis lathe, or do you also have a Y axis?

I did a simple drawing of my own to see the problems you had and if I could figure it out. It appears as though this is due to the size of the endmill. So in practice your walls and radii are perfectly drafted to the center of rotation, with walls always being perpendicular to center. This creates a problem for the endmill as it is offset by the radius of the tool. so in practice the smaller the endmill the closer the walls will be to the drawn size. At an endmill size of 0 the part would be a perfect match. C-axis contour does not use Y axis while milling as that axis is the substitution, and there-in is the problem.

I've been programming a lot lately in full 5x and been running into a problem. This is on a Mazak Integrex I300 but I've seen it on my other posts for 5x. So the issue is the rapid moves between cuts. The machine shudder steps in the rapid and immediately smooths back out for the cut. When I turn on endpoint display I can see that it is creating 5x rapid moves, however the moves aren't really close together, they're spread out between points. This issue becomes quite a bit worse with the 3D paths with tilt to avoid turned on. Is there a way to avoid this or a setting I'm missing?

I work in the same sector. I don't think I would consider FBM for anything we do. The tolerances we deal with tend to push me away from FBM. Also, the setup is super finicky. You have to get everything perfect before it will function, and even after that you're going to be editing what it puts out quite a bit. From what I've seen of it, it still has a ways to go before being a fully functional part of Mastercam. I would hold off on it. However, me just saying things on this forum doesn't make them correct, I'd encourage you to try it out for a little bit, see if you can make it work. If not you will have all the reasons for yourself and be able to show your boss the problems. If it works you gain a powerful tool to do the simple programming for you. And hopefully share some of that knowledge here.

I asked this question about a week ago in an unpinned location. I got a response with this link. It's only up to date to 2017. https://www.dropbox.com/s/yf1f24epmubsfqg/ModuleWorks_-_Documentation.chm?dl=0 Thanks to scottm085
