Thank you brother.

Thanks for this breakdown

Superb 🙏🙏

Hello! I am from Bangladesh. I completed my HSC in 2022 with a GPA of 5.00 in general education. I now want to become a CNC programmer and machinist, but I do not know where to start.

There is a technical training center called BKTTC (Bangladesh Korean Technical Training Center) that offers a 3-month machine shop and CNC machine operator course, as well as mechanical AutoCAD 2D and 3D. I have decided to dedicate myself to learning these skills.

Could you tell me about the future of this career path? Is it a stable job? Are there any chances of losing my job? Are there any better alternative careers that I could consider with great potential for growth and earnings? Will learning CNC help me achieve my goals, or will it be a waste of time? I would like a clear and conceptual solution to my situation.

After completing these courses, I want to go abroad to work as a CNC machinist because there is no opportunity for growth or a happy life in Bangladesh. Please give me the best solution for my career. I am looking for your support.

Thank you!

Top notch tutoring

I went to school for this and they didnt explain it this way. Though I passed I took me a minute to realize the puspose of the 1st 4 lines. Thankyou

I DON'T KNOW IF YOU STILL READ COMMENTS BUT THANK YOU, SIR.
I took a photo at work of the first line of the last program i ran, and sure as anything, my FANUC MAG FADAL follows this BASIC PROGRAMMING TO THE LETTER..

FANUC PROGRAM: THIS WORKS, SO BEFORE YOU SAY SOMETHING IS WRONG, YOU ARE MISTAKEN.
HERE IT IS:

N2
T2 M6 G0 G90 X21.102 Y-1.968 S1250 M3;
G43 H2 Z1.T3

CHOOSE TOOL #2 (T2 M6)/RAPID TO (G0)/ ABSOLUTE POINT (G90)/ TO X-AXIS 21.102 AND Y-AXIS OF -1.968/ TURN ON SPINDLE TO A SPEED OF 1,250 RPM/ CLOCK-WISE;

PICK THE HEIGHT (G43)/ OF THE SECOND TOOL (H2) WHICH IS TOOL 2's PROGRAMMED HEIGHT ABOVE THE WORKPIECE. THIS HEIGHT HAS BEEN DESIGNATED AS 1" THROUGH USE OF A 123 BLOCK/ T3 GET READY TO CHANGE TO TOOL #3 IN THE PROGRAM'S SEQUENCING

NOT QUITE SURE WHY THEE PROGRAMMER ADDED IN T3 AT THE END, but it works and that's that. I imagine it is this, though:

T2 is a chamfer
T3 is an endmill

But in the example that I broke down here at the start-- the G43 H2 Z1. T3 block-- the next 6 lines of code run before the tool actually changes to T3, which is an endmill. So I am guessing that the prgrammer could have left that in or out in the programming of the second op (N2). Yes? NO?

Well explained, thanks for sharing valuable knowledge
Stay blessed

thanks for the reminder.🙂

Dope vid

Wow... Very good.. You have a gift for explaining 😊

Thank you

could you make some more programs samples
