RE: ISO vs conversational code Most of the machines in our workshop are programmed using ISO. We decided to keep the control running ISO codes because it means that once the operators has learned the codes for one machine, he has a good grounding for programming the other machine. It makes it easier regarding cnc training if all the machines talk the same language. Anyway, I've mananged to edit the post to produce the output I wanted. Thanks for the help guys. If anyone needs help making similar changes just post a message & i'll try my best

Thanx for the feedback I think i'm getting nearer to my goal My employers are keen that the control stays in ISO for reasons I wont go into at the moment. After a bit of playing around with the codes & trying a few test examples created using Mcam, I've found that the code it produces isn't actually that different from what we use when manually programming the machine. Below is a liat of the differences that I wish to change if possible??? A) Simple one to start with I want the last M-code of the program to be M30, not M02 - this will rewind the program once it's finished running & makes it a little quicker for repeat jobs. We work on the machine using absolute programming ONLY[G90), but the last few lines of the code that Mcad produces look like this code: N484M5 N486G91Z0. N488X0.Y0.A0. N490M02 Why does it switch to incremental programming(G91) on the last Z move? & is it possible to force it not to do this? and finally.... C) This is regarding tool Z lengths & offsets. The Mcad code includes lines such as this code: N100G99T4L0.R12.5 N102G99T3L0.R5. N104G99T5L0.R5. But these are useless for our machine, as the tool lengths, rads etc... are inputted manually by the operator after touching on the job datum with the specified tool. The reference offsets are entered into a tooling chart on a seperate screen on the control. So I would like to remove the G99 codes & instead, include a G17 on the same line as tool change. The G17 calls the offset of the tool from the reference chart & should look like this N001 T3 M6 G17 I dont even know if any of these changes can be made or even if I've explained it very well. Look forward to hearing your suggestions Thanks [ 04-18-2002, 12:06 PM: Message edited by: -=ViBeZ=- ]

Thanks for reply OPPIZ. I'm not 100% if it uses (G-code) or conversational(m-code) I'm guessing it would be classed as ISO as it uses G-codes for the axis movement & M-codes for spindle/coolant control ect.... I loaded the heid_I.pst & it looks a little more like the manaul code I use to programme the machine. SO my question now is, whats the best way to go about finding & converting the post so that they both match? TIA

I'm just starting out with mastercam & learning to programme using cam software. I'm running through the tutorials provided with the software & have come unstuck on the post side of things. I'm 99% sure that we use a Heidenhain tnc 355 control for our milling machine, but when I choose the MPHEID.PST file, the code it produces is nothing at all like what the codes we use to manually programme the machine Do I need a specific post for this control or I am doing something drastically wrong? Thanx in advance
