Показать описание
G41 and G42 are important codes to learn as you endeavor to become a better CNC programmer. These codes help you get the most life out of your tools and save you time when tools wear and parts begin to approach their tolerance limits.
Try and memorize these codes while you wait for the next video.
Whether you are a manual machinist, a hobbyist or just interested in learning how CNC programming code is structured, then this video series is for you. This series will teach you all about programming language so that you can manufacture parts without the aid of CAM software.

Upcoming videos will cover dozens of codes and their proper usage including troubleshooting common code problems.

Learning how to program with CNC code will open up many opportunities for you in machining and manufacturing.

Please feel free to message me if you have any questions or would like any further help in CNC machining. I am a machinist by trade and worked as a CNC machinist for a decade before beginning my teaching career in machining and CNC programming.

When I worked as a CAD/CAM programmer, I used to program a 0.01 mm diameter tool (end mill) this provided flexibility for the operator to select a range of re-sharpened end mills with specifications on the max/min diameter. Needed to provide lead in and lead out paths outside the machining envelope when evoking/cancelling the offset.

It is a little bit confusing. Is there a reason that you have different values for g41 and g42?

Is it below my understanding is correct

Material on right side of tool while traveling from bottom to up G41 will shift cutter towards Left and away from part

Material on left side of then tool, while traveling bottom to up G42 will shift cutter to right side and away from Material.
