I am knew to the haas does anyone know how to do a pocket cycle using the g150 my pocket is 4x4 .250deep with .250radius on the corners.

[WITOMCIO]

Use 1/2 carbide end mill(.250 radius), predrill .500 or bigger(better) hole for clearance at X0.Y0.If step .300 is too much change J0.3 to J.15.
It is not machine proven program so be carefull running it.
hope it helps.
Subroutine O502 can be changed to cut different shapes nad sizes.
I believe , you have to use Radius Geometry offset of .250 for tool # 1.

Copy and paste program below and you are all set

Thanks for the reply I kind of understand how this program is running I just dont quite get the F50. and also the line on G150 P502 G41 D1 Z-.25 R0.05 J.3 K.01 F10. also say I wanted to add another pocket on the same pcs. using the same 1/2 inch cutter how would I add this to this program. my origin is in the same spot as my last pocket was my knew pocket center is going to be X-4Y-6 that is distance from the 4x4 pocket. this pocket will be 2X2 .250 deep. thanks again. Iam still trying to figure out this cnc thing.

If oyu have access to HAAS operators manual , G150 is fully explained.Maybe on HAAS website www.haascnc.com. If not let me know , I can post it tommorow from my manual.
G01Z.01F50. is just safe way to get .010 above part, and can be omitted.
G150 and so on , executes pocketing of profile defined in subprogram O502.
By adding X-4.Y-6.(watch out for decimal point, if you new in this) in the command G150 and defining new contour of another pocket by for example O503 you can do another pocket.
Not knowing how familiar are you with basic G codes, especially G90 and G91
is kind of hard to help.
Basicly command G150 works like this
You must tell in this command what is you pocket contour , by calling subroutine Pxxx, establish entry point by defining position X Y, how deep is the pocket by value of Z, what kind of step you going to use on pocketing, and other parameters like tool compensation, Z step(Q value) , return point (R),etc.
Good luck

hello witomoci thanks for the input it does makes sense to but I am not at the level of programing jet I guess I will still keep on using the manual way of cutting the pockets using g02 and g01.thanks again
buy any chance do you know if theres a way I can purchase a software that I can download on my computer to just play around on progaming some parts using g code and also have some kind of simulation to see how the part is cutting, i hope these makes sence. thanks again.

what are you using to comunicate with the machine "software"

[raymond1]

what are you using to comunicate with the machine "software"

I have no idea what you mean. the way i program my part is I write the program then I look and see if runs good on a hass simulator then I go the cnc HAAS download my program and run my part. I am trying to purchase a software simullar to the hass machine that I can download on my laptop so I can just practice.

[jackson]

you can down load demos of several different ones, but the reason i asked what your using to comunicate is because i wright all my programs in my comunication soft ware and it has some great featurs like back plot, program calculater, geometry calculator, and even estimates the time it takes to run the program

You can download this free simulator here http://www.cncsimulator.com/. I machine a lot of pockets and found the G150 to be very useful and a lot easier to use then hand coding the contours. Once you figure it out, you'll love it. Good luck.
