G91 works great for threadmilling as a sub. Use G90 for positioning to the hole, then go into a G91 sub to buzz the hole out. You could use G92, but that's a good way to crash the machine, shifting the work offset around. A good thing to keep in mind is, if you are sending spindle home or to a particular location using G53, G90 should always be added on the same line to be safe. If it modally happened to be in G91, chances are good the machine wont go where you wanted it to go. The same is true for G10L2 (or L20 for additional offsets) work offset setting. If G90 isnt specified on that line, and it was modally in G91, the offsets will be incrementally set! On your canned cycle line, I didnt see a specified G98 or G99 with the G81. BTW, I've been using G82 lately, because you can add a slight dwell to ensure your drill will go to the depth you want it to, and not rapid out when its "close" to depth. We've had that issue on the fanuc 15m. I like using G91 if I'm not using a finish bore canned cycle. If I'm just going in using G1 with a finish bore, I'll m19 the spindle, then G91 X slight move to move the finish bore away from the bore so it dont rub on retract. I have gotten bit on this in a counterbore! After cutting to counterbore depth, if M19, then incrementally moving away, it can pull the insert out of its pocket from rubbing on the counterbore! So back cut a bit before stopping the spindle to avoid insert rub when moving the tool away from bore.
The 2nd line below G90 should be X2.25 *Y-1.25* , not Y-1.75, right? (1,5+2*0,5)/2=1,25 In any case, the dimensions on the left side show that the Y side is 2,5 in long, but the those to the right say that the same side is 3,5 in long. Great video, by the way. Thanks for uploading. EDIT: Ok, I see you've made that mistake on purpose. I've paused the video to examine the drawing more closely and than I've written this comment. Silly me. :D Thanks again.
Hi, I'm new to G code, when you said you that this block is 3.5" by 4.5", Do I have to specify that in the code? How can I lock my axis to that size so the tool don't go above the specified number Exp 3.5" by 4.5" if that was my build plate? If I'm building a new cnc machine and my tool is in the middle, how can I set a homing for the tool? Hope you can help me thanks
No limits on any letter. When the control sees a open parentheses ...(... it ignores all code until it sees a closed parentheses...)... and then it starts paying attention again. So you can put enormous comments if you want to between parentheses and the control will ignore them all.
Regards! Excuse me for interfering, I would like to inquire, Can you help me, Can you offer me some software for home schooling that allows you to learn how to program and draw Cnc, They would like to offer me a note, a handout for learning, to learn how to use the programs, I look forward to your reply, Thank you for your help, I respect you, Zoltán Tóth.
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!
It's sloppy how he explained it. Absolute is easy because X & Y axis is positive all the time by starting at the bottom left of the part. Incremental means you're always moving your tool negative and positive. Which means your starting point will have to be different each time
Great video... i have questiin about gcode in mach3 sorry this not topic here.. am sure you know more about it) your help needs please..i have wrote down gcode by myself on notepad txt format am using x axis as clamping system linear movment in mini injection machine ...i put some codes on it and downloaded in mach3 some x axis movments and i want to use some codes as loop can repeated hole cycle till i turn off reseted button...some guys use m97, m47 but in my case no luck)) any help please??? for example in my case...g90 g1 x50 f 350 G4 P10 X0 x-10 X0 x-11 X0 (these above cycle needs to repeated... any codes as loop???)) Hope some can also help this if knows .. i really appreciated
It is a bit long, but it's worth reading. He was betrayed by his disciple. He was left alone by all his disciples. He was killed for others mistake. He was killed though he was innocent. His own brothers didn't believe in him. His mother had to watch him die. Everyone knew he was innocent but still they killed him. He is to be treated like Kings but he chose to serve us. He still forgave the people who crucified and mocked him and he said Father forgive them for they not know what they are doing. What has more greater love than this?. All for our sake. The man Jesus Christ. He showed us true Love. John 3:16 For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. But There's a happy news. He rose up again after three days just as he told. There is no greater blessing than having God as our Father. He's coming back soon. Let's all repent and turn from our old ways and prepare our hearts for him. This is the prophecy about the second coming of Jesus Zechariah 13:7 “Awake, sword, against my shepherd, against the man who is close to me!” declares the LORD Almighty. “Strike the shepherd, and the sheep will be scattered, and I will turn my hand against the little ones. This is the fulfillment of the prophecy. Matthew 26:31 Then Jesus told them, “This very night you will all fall away on account of me, for it is written: “’I will strike the shepherd, and the sheep of the flock will be scattered.’ This happened near 30 AD. Hosea 6:1-2 Come, let us return to the LORD. He has torn us to pieces but he will heal us; he has injured us but he will bind up our wounds. After two days he will revive us; on the third day he will restore us, that we may live in his presence. In prophecies 1day is equal to 1000 years. Which means after two thousand years Jesus will return again. And on the third day which is the 3rd millennium, we will live in his sight. We all know we cannot see God's face and live on Earth. So it's the second coming of Jesus. Luke 21:11 ► There will be great earthquakes, famines and pestilences in various places, and fearful events and great signs from heaven. Matthew 24:6 You will hear of wars and rumors of wars, but see to it that you are not alarmed. Such things must happen, but the end is still to come. We are the witnesses of all these things. From the death of Jesus to 2030 there are 2000 years.9 years is left until the 2000 years are complete after Jesus's death. Jesus is coming soon. Let's all repent and turn from our old ways and turn to the Lord. Praise the Lord. Peace and Love to you all. Easter is pagan, the resurrection day of the Lord is correct and please stop taking the Lord's name in vain like saying omg or using it with a bad word or taking it in anyway that is in vain. Even the devil trembles in his name and we shouldn't use the powerful name like that. For the people who says Jesus is not God here's a verse. Isaiah 9:6 For to us a child is born, to us a son is given, and the government will be on his shoulders. And he will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace. God bless you all. Please spread this message to the ends of the world

Thanks again.
Hi me also noticed. I think he intentionally made a mistake. To show that G90 is better preference. And G91 a bit complicated.
Can you make a video on parametric programming please?
Absolute is better, less confusing. Thank you for your video.
muy bueno felicitaciones
Excellent and brilliant explanation,,,,thank you very much for sharing this information, ,,,ser
Does the program need to know what plane will be used ?In this example,xy plane will be used.Btw,what G code # specifies xy plane?
do u have new youtube channel? ur good at explaining... cause this is 2013.. i hope u have new channel.. i want to watch it
Thank you kindly
I am thankful to this elementary lesson. Sir.
Nice explanation
very easy to understand, thanks for your help Bro
ok so basically this could be summed up with: G90 is base off G54 (etc) off set and G91 is based off position where you are at.
Good introduction Thanks
No more videos?!
very well explain JAZAKILLAH
Hi, I'm new to G code,
when you said you that this block is 3.5" by 4.5",
Do I have to specify that in the code?
How can I lock my axis to that size so the tool don't go above the specified number Exp 3.5" by 4.5" if that was my build plate?
If I'm building a new cnc machine and my tool is in the middle, how can I set a homing for the tool?
Hope you can help me thanks
Which software is used to learn and practice about G-CODE??
which comand implies the different hole diameter
very good
Thanks bro
thanks a lot ...
How does this program look like if G91 will be used instead G90 starting from N005-N050?
nice,well explained. thanks :)
nice
Thanks too much.
some error @15.00 (Y should b -0.75 for G91) pls correct me if m wrong
you are absolutely right!!
nyc explanation
idiotic imperial system ......
I like
0.5+1.5+(.5) = 2.5 ???? lets assume the bottom is .5 (right side)
1.75 * 2 = 3.5 ???? (left side) can u please explain this to me? T.T
is there a limit to the number "O"s you can have in a comment?
No limits on any letter. When the control sees a open parentheses ...(... it ignores all code until it sees a closed parentheses...)... and then it starts paying attention again. So you can put enormous comments if you want to between parentheses and the control will ignore them all.
The program does not read comments so you can put what ever you want there.
So no you can put as many O's as you want.
Can anyone help me to write the CNC program (Circular slots in a rectangular block )??
Yes
Why does N030 have a larger hole?
Tapper turning ka program kaise banaae sir

@@Buster_friendly Nice explanation. Come this 2nd January 2020 I be moving from manual to CNC machinist.
How to used to r
how to u know Z plze
When you probe the part to get the zero position you set G54. probing X,Y and Z.
