Навіть на засіданні гуртка науково-технічної англійської мови Sci-Tech Talks торкаємось прикладних фахових тем:
In today’s STT 2.0 meeting, we continued the topic of CNC and considered a simple program in G-code with explanations of the calculations of coordinates of motion. It involves milling sides of a part 80×40 mm with a ⌀8 mm end mill.
Also, we watched a short video about the operation of the tool changer of a CNC milling machine.
Here is the simple program that we considered with comments.
