Basic CNC

In this video there are three basic CNC programs. The ist is a straight line program. In the 2nd program it is an angular program and the last one deals with a basic circle program.

This is what i want to see. This video contains pure information, no dumdum imformation that nobody asked for. Thank you.

I have watched soo many videos about I and J programming, but this is the video that taught me how to actually use it.

I'm going to my local technical college for this. Thanks for the video. Now I know a little about what to expect.

[snaprollinpitts]

thanks Morris, I always thought that doing this was a lot harder, but you make it look easy

I run cnc everyday and that is a very good starting point all the offset codes need to be learned after you understand how the machine would move otherwise ur crashing people that are complaining bout g54 (vice) g43 (height) g41-42 (left or right cutter comp) that's more in depth and if you already know it that's great but some people are really just trying to understand basic movement

[officialaaronjames]

Great video.. It really seems so simple the way you just explained this!

[hudsonriverlee]

Wow. I am amazed at how much I just learned in such a short period of time. It will be interesting to grab some graph paper, and pre plan a program just to test out my Cnc Machine after it arrives, 25 why sit around.. lol.. I thought the mapping f the circle was going to be several lines long. Well done .. lee from Norway, Maine...

wonderful professor. i wish i had him in my class. i do not understand the one i have in my class. please make more videos. you are the best

[ritviksaxena]

this video was really beneficial for a newcomer like me. Great!

[rufusleers]

Fantastic! Now I'm ready to go crash some machines! (Joking)

[professorjim]

If I remember right, the VMC's I've run that do not require G43 pick up the length offset how you do an M06. But these are older controls, probably few in use now.

Hi there.

While comments below indicate it's not perfect, it's a perfectly good staring point and it really is appreciated.  Some of the constructive comments are helpful additions also, which this comment isn't ;).

Many thanks...  Clark

[literoadie]

Thank you very much, a very helpful video!

[maravatio]

Thank you very much for this interesting video!... Very well explained!!!.

Thank you very much for adding the tutorial.

Since I recommend this video to persons who are absolute beginners and who will later be in a seminar I conduct, I should point out that what Mr. Morris labels "Home" is "Work Zero" in my notes. In the old, old days we would have called it "Absolute Zero" but contemporary CNC has a hierarchy of absolute systems. The machine system is the bottom (ground) system of the hierarchy and the work system is the top system. I suspect that if Mr. Morris were demonstrating on an actual machine he would have found the zero offset from machine zero to work zero and put it in the 01 Settable Zero Offset and included G54 in his first motion block.
   With regards to compensation for tool length offset, if Mr. Morris set up the machine with the tool as a reference onto itself (relevant for setting the zero offset in Z), there is no length offset to consider. This would explain why there is no D-code (or G43 and an H-code if you are thinking Fanuc). Of course, he would be in crash city if he changed to a tool of longer length.

When to use incremental values in a program. In a book I read it was calling certain parameters in the word to develops a radius, in incrememtal. U E, I K ect...

[professorjim]

G93 is usually Inverse time federate. Equal to 1/the length of time it takes to complete the move. Used to coordinate feed between linear and rotary axis movements.

[giuliobuccini]

As I know I and J parameters are to be specified in relative coords even when G90 command is issued (source: LinuxCNC 2.6.7 manual, page 252). Otherwise you have to issue the command G90.1 before.
Anyway great introductory video to fix basic concepts!

[manojdhanda]

thank you sir i did not have solid basics but i achieved which is sufficient for my exam

[JohnDoe-otle]

Hi, great video. Shouldn't we have G02 X2 Y3 I2 Y2 (x and y after G02 are for end point).
