Heidenhain programming ?

If you have a good enough meter, you can monitor the voltage, one leg at a time, and it will store and recall the high and low reading. My Fluke does this. This will tell you if a leg is dropping too low.

According to your program, your drilling in .4480" with a .750" cutter. at 2500 rpm. then clearing a 2.008" circular hole.
possible overload condition, seeing as your running on a phase convertor?
what material ( i ask this because of the slow 8ipm feed)? and is the cutter center cutting?
have you tried small peck amounts?

<<<,


No yah didn't

every time you post there are new details, it is very difficult to try to help if you do not clearly and precisely explain the problem.


Ok

Does it stop a the same point in the program?

can you restart the spindle by stopping the program[STOP key, manual mode,spindle cw switch]?

will the program ALWAYS run with no part in the machine?

If you fire the spindle and walk away,will it randomly stop?



BTW, you only need an m3 at the beginning of the program

roseng, I'm milling the inside and outside of a intake manifold which is aluminum casting. The inside is already hogged out and I'm milling the inside dia. to 2.004 and then bring the tool which is .500 dia, two flute to the outside of the intake and cutting the outside dia. to spec. I haven't tried doing smaller pecks as this program has run several times in the past with no problems. the spindle seems to stop about the same point each time, always in the cyc section of the program and not during any L moves. Gus suggested trying it in manual mode to see if the spindle stops. I'm going to try that and will get back later.

found the problem!!!! Today I thought I'd load a program from the previous owner to see if his program would run the full program without stopping and it did. that told me something was wrong in my programs. I then started to really look at his programs vs mine and noticed that he didn't have M03 programmed at the end of every line of code. I then noticed that his programs only showed the M at the end of each line of code. So with that info I went into my programs and deleted all the M03 except the beginning M03 and then left the M05 at the end. That fixed the problem. Ran my programs without any stoppage, so it looks like I corrected the problem. I tried 2 different programs and they both ran good. I guess the program saw each M03 at the end of the lines and got confused and stopped.
Want to thank everyone for their help. Being new to this CNC programming sure is fun ha ha. Anyway I might be slow to learn, but I don't give up easily.

Again Thanks Guys.

hmmmmm, the m3s shoooooooudln't cause that, I frequently have orphan M3's in my programs[from adding sections, troubleshooting pieces, or starting mid program for one reason or another]

Hey if it works now, awesome!

hi guys i love all this talk. being a non cnc,er i learn something every day.
thanks and keep it up

Well the spindle started stopping again after running correctly thru several milling's. I decided to reduce the spindle speed from 2500 down to 1500. the spindle speed was showing 3750 on the controller, so thought that maybe was too high. Reduced it to 1500 and the spindle speed on the controller shows 2500 and I ran several programs without any more problems. I don't understand it, but if works I won't complain.
