Dear everyone I personally and really thank you all for your sound advises and suggestions. This is great teamworks, also good for future people to look at us and our situations. I work very hard in the Eduaction Institute for engineering students with Mastercam v9.1 and the old machines for their execrises. I only started to learn the Post Process file writing/modifications, one and half months ago at the advices and encouragements of the teachers as well I am only one student to do this Post tasks. I did managed and succeeded on Latest version of Post (MPMaster v9.13) for Fanuc machine. So I do not ask for free posts or seek to 'steal' from you. The reseller told me that he do not know very much about Heidenhain TNC 155. I had to do on my own efforts to gain further experiences and new skill with endeavours and without giving up. I now know that the members of eMastercam are great people. However Heidenhain TNC 155 is more fussiest ever I have seen. The control won't operate over a tiny error then the programs become frozen. I use MPHied_c v9.13 because it is almost acceptable to TNC 155 than the other post files, even supplied files by the reseller and some of you. Here's the file which I had tried on MPHeid_C Post v9.13 But the problem - I tried to insert the hard core of 'strf' on liner movement - feed to suit the TNC but on line 10 & 11 show double 'F', if I remove 'strf' then 'F' on end of lines 13 to 17 disappear, then TNC won't run without "F" or on double "F". Please advise me by showing me the hints and line numbers in the Post, please do not give/supply me your post files, as I must learn and overcome the difflicults. 6 TOOL CALL 1 Z S1000 7 L X-20.000 Y+71.000 R0 FMAX M 8 L Z+20.000 R0 FMAX M03 9 L Z+10.000 R FMAX 10 L Z+0.000 R F F100. <-- see "F" "F100." = double 'F' 11 Y+51.000 R F F1000. <-- see 12 CC IX+20.000 13 C X+0.000 Y+31.000 DR+ R F <--- must have 'F' on end of circular movement 14 L X+15.000 R F 15 CC IY-16.000 16 C X+31.000 Y+15.000 DR- R F 17 L Y+0.000 R F This is an correct example of old NC file which TNC 155 operate effectively and perfectly. 6 TOOL CALL 1 Z S1000 7 L X-20.000 Y+71.000 R0 FMAX M 8 L Z+20.000 R0 FMAX M03 9 L Z+10.000 R FMAX 10 L Z+0.000 R F100 11 L Y+51.000 R F1000 12 CC IX+20.000 IY+0.000 <-- note to Dave Thomson 13 C X+0.000 Y+31.000 DR+ R F 14 L X+15.000 R F 15 CC IX+0.000 IY-16.000 16 C X+31.000 Y+15.000 DR- R F 17 L Y+0.000 R F Note: Dave, Can you tell me where and which line numbers of MPHeid_C file as you mentioned "Find where this is output - pcir - and force i and j using *i, *j" Also I was able to solve the problem on the drill cycle set up but the TNC 155 rejects this below NC file because of no height references, please notice the numerical figures of height references and feed on end of TNC 155 NC file example - How can I solve the problem or write down the file?

I tried to used the MPMaster v9.13 Post for Bridgeport 4 Axis Horizonal Milling Machine with 320D control Can anyone advise me how to set the constant WCS with only G54 but no variability with the others -G55, G56, G57 and etc. Thanks in Kind Advances Regards Terence

The MPHeid_C worked well and I am still working on Post Processing File for an Educational Institute as TNC 155 made very, very fusses after some trials. I hope that you may be able to give me some assistances or hints. Here's an example of TNC 155 NC Profiles with some notes to you: 10 L Z+10.000 R FMAX 11 L Z+0.000 R F100 <-- Note: "R" must be used before feed rate 12 L Y+34.000 R F1000 <-- " " 13 CC IX+3.000 IY+0.000 14 C X+0.000 Y+31.000 DR+ R F 15 L X+15.000 R F <-- "R" & "F" must be used at the end after rad. compensation 16 CC IX+0.000 IY-16.000 <--- Must have 'IX__.____ IY__._____' together at same time 17 C X+31.000 Y+15.000 DR- R F 18 L Y+0.000 R F 19 CC IX-6.000 IY+0.000 20 C X+29.243 Y-4.243 DR- R F 21 L X+4.243 Y-29.243 R F 22 CC IX-4.243 IY+4.243 23 C X+0.000 Y-31.000 DR- R F 24 L X-25.000 R F -- -- -- -- -- 41 CYCL DEF 1.0 PECKING ) 42 CYCL DEF 1.1 SET UP+1.020 ) Please note the 43 CYCL DEF 1.2 DEPTH-15.000 ) cycle def. must 43 CYCL DEF 1.3 PECKIMG+2.000 ) be input as the 45 CYCL DEF 1.4 DWELL+0.000 ) TNC 155 won't 46 CYCL DEF 1.5 F1000 ) operate on ISO so tell me how to block "R" & "Q" Can you tell me how to do on Pst?

To anyone who may be able to assist or give advices to us. As I am placed into special tasks for the Educational Institute which it has introduced the Mastercam V9.1 to the Engineering CAM/CAD courses to phrase out the old versions and old Post files. As requested, I, a student, am starting to learn in a month ago and work on changing the latest Post files for them. I succeeded on one machine but the other machines, I am seeking the suitable Post files for bridging between the machines and Mastercam v9.1. The Educational Institute has - *ANCA Vertical Mill Machine with ANCA 2000 Control(Australian) *Cintimatic (1960) Mill Machine with ANCA 2000 Control (1988 and Australian) *Okuma Lathe LC10 with Okuma OSP500DL Control (1982) *Zenford Vertical Mill Machine (1982) with Siemens Sinumerik 820M (1988) *Latest one - DMU 50 eVolution 5 Axis with Siemens 840D. Our reseller told us that he could not provide due to lack of knowldges on these machines. I hope that anyone can give us the solutions on the types of Post files to match with them. Thanks in Kind Advances Sincerely Terence

Big apologies to you for my big clerical mistakes on the name of Post file - should be MPHeid_C v9.13 not MPMaster. But big thanks to some of you for heap helps as I have learnt alot from you. My reseller told me sometimes ago that I have to do/work out on my own to meet the machine/ control's systems. I hope that I would get some further advices. Here's my rewritten questions Can anyone help or give advices/suggestions/ instructions to me on how to change the MPHeid_C Post Processor file/program to suit the Heidenhain TNC 155 and Mastercam v9.1? I had tried to change the MPHeid_C Programs to meet the requirement of this control for Bridgeport vertical Mill machine 'Interact 1 Mk 2' (18 years old!) at the Educational Institute where the engineering students use Mastercam v9.1 and this machine with Heidenhain control for their exercises. But no success! On header - must have the profile like 0 BEGIN PGM MM 1 TOOL DEF 1 LX.XXX RX.XXX 2 LBL X 3 MXX 4 L X_.____Y_.____ R__ FMAX MXX 5 LBL X 6 TOOL CALL X Z SXXXX ETC But for circular interpolation must be IX_.____ IY_.____ not I_.____ J_._____ Also the correct Drill Cycles profile to suit. I hope that any of you can help us. Sincerely Terence

What is the chances of Mastercam being ported over to an UNIX/LINUX even an OSX Environment. I have read of people trying to use a CAD package within Vmware or WINE but it is cumbersome and really isn't a good use of resources. Windows XX is a non moduler fairly unreliable OS which really doesn't allow for optimiztion of the OS for a CAD package. And Unfortunately the Intel based CISC processor due to Microsofts need for backward compatibility is not as powerful as it should be. (Protected mode stuff). The Clone PC has its idiosyncrasies within the different components. Thus sometimes leading to a big head ache when looking for compatiblity. Anyway I would really love to run Mastercam on a indigo SGI box. Thankyou sorry about my raving.

Is Mastercam (V9) supported within a Simultaneous Multi processor environment. Basically if we went out and bought a multiprocessor (Intel based architecture)machine would it improve the performance of Master Cam. If so what facets within the Mastercam package would best benefit.
