 How to Use GD & T in Drawing Study: A Simple Guide for Beginners         If you have ever glanced at a blueprint and been puzzled by the abundance of symbols, arrows and boxes rest assured you’re not the only one. I vividly recall the occasion I encountered a drawing featuring GD&T (Geometric Dimensioning and Tolerancing). It was akin, to deciphering a language. However once I grasped the significance of each symbol and their application the process became significantly smoother. In this piece I’ll guide you on how to interpret GD&T when examining engineering drawings in an approachable manner. No heavy technical words, no complicated explanations; just straightforward points that anyone can follow. Whether you’re a student, a machinist, a CNC programmer, or someone new to manufacturing, this guide will help you feel more confident when reading drawings. What Does GD&T Mean? It is a language employed in enginee...

 Simple Turning Program What Is Turning in CNC? (Simple Explanation) One of the most frequent operations which is performed on a lathe is turning. Simply, you clamp a round workpiece to a chuck, spin it and cut the material to produce whatever shape you need- normally a cylinder shape. Turning in an LMW CNC lathe is controlled by a program programmed in G-codes and M-codes. The machine just proceeds as instructed line after line. Before Starting The Program (The Basic) Work Offset (G54) - We have tell the machine, where is the part Tool - T0101 - There 1st "01" is Turret Station Number & 2nd "01" is Tool offset number Spindle Rotating Direction - "M03" Clockwise rotation for Left hand tool / "M04" Counter Clockwise rotation for Right hand tool. What is "F" - Feed value. Turret movement in revolution per minute" Safety program line - G00 G40 G90 G80. "G00" Rapid Movement "G40" Compensation Cancel "G...

  What Are G-Codes and M-Codes? A Simple Explanation for CNC Beginners When you have ever seen a CNC (Computer Numerical Control) machine in action, you have probably asked yourself, how does this machine know where, how fast and when to stop? The solution is in the form of what is called G-codes and M-codes. I recall, when I was introduced to the concept of CNC machines, that I was utterly confused when I saw all those letters and numbers displayed on the screen. However, as soon as I figured out the rationale of G and M codes, it all became clear. In this article, therefore, I will simplify it to you in as simple a manner as possible, not a single piece of engineering jargon, but a plain old-fashioned explanation that every common person can easily understand. What Are G-Codes? They instruct the machine on the route where to reach and how to reach it. The G can be translated as geometric since these codes are used to regulate the motion, and location of the tool used...
