So heres what is really throwing me off. If I rotate the tool plane in a direction that changes the Z it will post out and run fine but if I rotate around Z like in my example above it will not rotate. Attached is a picture of the rotation that worked along with the posted code, G00 G17 G20 G40 G80 G90 G91 G28 Z0. G28 X0. Y0. M79 M11 G90 A0. C0. N1 T1 (0.75 FLAT ENDMILL) M06 G54 G17 G90 G00 A-90.

Hey thanks for the reply. So I am using all of my rotational planes from a single point that is my G54. When I try and run this code on our machine it will run it but it will not rotate the C axis it just cuts as it would if the G68.2 was not there. I have tried to contact Methods a few times for OKK support but I guess they are still learning about the machines because it usually didn't lead to any answers to my questions.

Hi, I was wondering of someone could help me out with the coding of G68.2 in mastercam. So I am currently trying to machine a part on an OKK table-table machine that the back side of the part sits just outside of the machining area. My plan was to machine half the part then rotate the table so the back is in the front and accessible by the cuter. So my G54 is set to the center of rotation on the A and C axis, then I have my second Rotated coordinate system in the same location just rotated around Z at 180 deg. When I create any tool paths with this rotated coordinate system it does not actually rotate anything A and C stay at 0 instead of posting A0 C180. However if I do the same process and rotate the coordinate system around the A axis 90 deg it will and post A90 and C0 which would be correct. If anyone knew what I was doing wrong with the 180 degree rotation I would appreciate the help. I posted Pics of my 2 coordinate systems and the posted code. Thanks for any help I can get.

I was wondering if anyone who has experience with G68.2 would be able to figure out why my posted code keeps throwing up "5462 illegal command in G68.2". I tried moving around my G54.2 P1 and the G05 P10000 commands but I am still getting the error. I posted the code below. I appreciate any help I can get. G00 G17 G20 G40 G80 G90 G91 G28 Z0. G28 X0.

Thanks for all the replys its all super helpful info. So what I have gathered so far is this... Rotary Dynamic Fixture Offset (G52.2) is used for 3+2 axis work and it can not be combined with G43.4 (TPC) but it can be combined with Tilted Work Plane Comp (G68.2). In order to use simultaneous 5 axis machining we would use Workpiece setting error comp (G54.4) and this can be used combined with G43.4 (TCP). So all of this has raised a few more questions about setting up the work piece and translating our Mastercam WCS to the machine. For Rotary Dynamic Offset and work piece error compensation I was under the impression that we would set our G54 to the true machine center of rotation for X Y Z (we have a trunnion table). Then for the fixture offsets we will set those to where the part is located on the table which is not at the center of rotation. Then in Mastercam I can put my WCS on the model that corresponds to where I set the offset of either G54.2 or G54.4 depending on our operations. I attached some pictures of our 2 offset screens on our Fanuc controller. Thanks again for all the help! ).

So I tried moving the G54.2 to right after the G55 and I still got the same error when it hit the G43.4 line. If I run the machine simulation on the Fanuc controller it will play through the entire thing without any errors... Thanks for the replys. G00 G17 G20 G40 G80 G90 G91 G28 Z0. G28 X0. Y0.

Hi, We have recently added Dynamic Fixture Offset to our OKK VP600 machine and I am having trouble getting our code to work. I have tried going through our OKK distributor and MasterCam post distributor but as of now no one has known what the issue is. Whenever I run a code that has a G54.2 in it I get an error that says "Illegal command in the G43.4/G43.5" If I take the G54.2 line out the will run but then it is not accounting for the offset in G54.2. I posted a sample of our code below, Id appreciate it if anyone could take a look and see if they know what is missing or in the wrong place. Thank you.

That was how our post processor posted the code out. I was just reading up on using FPM verses inverse time. Ill bring this up when I talk to our post processor developer about our other issues. Thanks for the info

This post processor was bought for this machine through our mastercam distributor. I currently have a service ticket in with them but still haven't heard anything. While I am waiting I figured i could post here to see if I could learn anymore info and if it was actually the post processor or if I was doing something wrong. Thanks for the reply!

I recently started trying to perform multi axis operations on our OKK VP600 5axis. Up until this point all of our 3 axis operations worked fine with our mastercam 19 post processor. Earlier I tried to run a simple multi surface code that when I ran it threw up error"PS5421 illegal command in G43.4/G43.5" on our Fanuc series 310is-model A5 controller. The simulation in master cam went fine and the simulation on the machine went fine. I've never had any issues running multiaxis codes on our other machines which have a rotating head as opposed to this machine which has a trunnion table. I posted a sample of my code below. I know this has something to do with TCP but I am unsure how to fix this. G00 G17 G20 G40 G80 G90 G91 G28 Z0. G28 X0. Y0. M79 M11 G90 A0. C0.

This is my first time trying to create a custom thread mill in mastercam 19. I followed some previous forms/tutorials and am still having issues. I am trying to get it to create a single point insert thread mill (Kennemetal 5593134). I have tried 2 ways so far first I tried importing the tool file that i downloaded from kennametals NOVO app which gave me the correct geometry however the threads that mastercam was overlaying did not line up. Second I brought in a DXF of the tool and sketched out half the profile then tried to create a tool with that but it came up with a different geometry and the threads did not line up again. I attached some pictures as well as the stp file of the tool. I would appreciate any help I can get on here especially knowing if this tool is even possible to use with mastercam thread mill tool path. Thanks!
