Introduction to CNC Programming (Udemy.com)

Marc is an excellent teacher. The way he engages with his students and presents the fundamentals of CNC machining enables almost anyone to follow along. As an electrical engineering alumnus myself who uses Fusion 360 to model parts for 3D printing, I found the step-by-step code breakdowns particularly informative. I also found his explanations of key machining concepts crucial to programming a part. However, with that said, I've also noticed a couple of opportunities for improvement, such as the labels on some slides in the radius section and the addition of a G40 command after the Z rapid travel command in the thingy slot example. I look forward to visiting gcodetudor.com and exploring all the great resources it has to offer. Finally, I would like to thank Marc for taking the time to create this very informative course and recommend it to anyone interested in learning about CNC machining.

I'm in my 50's and have decided to make a career change to become a machinist. It's a long story. It's taken a few years and I've finally found someone to give me a chance as a trainee. This course has given me a good basic understanding of how these codes work and has also given me a map to follow to improve my skills as I gain competence. Thanks for this course I really appreciate it.

As a newcomer to CNC programming: The course was easy to follow along, with the part diagram and GCODE being written side-by-side. I liked the cutting tool position being displayed over the diagram at each stage of the GCODE. It would be cool to also display an animated rotation of the cutting tool, with a line position (tool-path: Male - Female - Online) overlay on where the cutting tool travels. It is explained in (section 2. Cutter Compensation) but it would be cool to see a animation of tool-path, and a more in-depth description of how a CAM program understands where the cutting tool ends up, such as how it positions around a 90 profile, with > (tool-path: Male - Female - Online). I understand this is a fundamentals course, and found it helpful for starting out. I will be checking out your other courses to progress my knowledge.

I was surprised at how well the instructor has laid the whole course out. As a South African learning opportunities are rare and when one pops us the lecturers and instructors just ramble everything down and hand you papers and expect you to understand. This was the complete opposite and the instructor has really take his time to make sure that students not only understand the course but he took is time explaining certain things with patience and also made sure that if it was a difficult topic to have more than one example of the topic. I just want to give our Instructor a big big Thank you. I am extremely grateful to have found his course and to have him explain things and break sections down in an orderly and understandable manner. kindest regards, all the way from South Africa, Valrize

I bought this corse 3h ago and i already finished, it is quite light to digest even at 1.25-2x the video speed. I am happy of having demystified this topic. The course it is very valid although i would recommend the author/instructor the following: a) The course is too dry just following examples on video, i found out there are free online G code simulators like https://ncviewer.com/ which i used to test the examples in the course and it works pretty nice. b) Lecture 20 was the most difficult to understand (use of a face mill) for someone newbies like me....you could add a picture of the main tools used during the course: slot drill, end mill, face mill and a short verbal explanation. c) You could use editing software like Camtasia to add visual comments to the raw video e.g. pointing out were will be the tool positioned e.g. when lowering in the Z-axis to begin cutting (not depicted in any of the videos/lectures)..or for example in the very last lecture of the positioning of the tool to mill the Thygy slot....just making it evident that the tool is offset -4mm because its radious is 8mm. That is it!....I did learn something today. For that, thank you very much!

si

Explained clearly and descriptively

It would be lot better if we had and video of mashine operating

Great course for beginners! Loved it

His accent is very difficult to understand and captions don't match at all with what he is saying

Clear instructions and easy to follow

Very Basic but good examples with explanation
