PART 1: FANUC 31i-B The Kinematic RealityFanuc dominates North American/Asian 5-axis shops (DMG MORI, Makino, Okuma). Its strength modular G-codes becomes a weakness when kinematics are ignored. On a head-table machine (e.g., Makino D500), the A/B axes pivot the spindle. A G-code error here doesn’t just misposition the tool it makes the entire head assembly collide with fixtures. Your…

Understanding axis naming conventions in CNC (Computer Numerical Control) machines is critical for efficient programming, operation, and troubleshooting. Whether you’re working with a simple 2-axis lathe or a complex 12-axis mill-turn center, adhering to standardized axis nomenclature ensures precision and clarity. This post explains the rules governing axis naming, rooted in international…

Rough turning is a foundational process in CNC machining, where excess material is rapidly removed to shape a workpiece close to its final dimensions. Efficient rough turning minimizes cycle time, reduces tool wear, and prepares the part for finishing. Central to this process is the rough turning cycle, a programmed routine that automates tool paths and parameters. In this blog, we’ll explore how…

Peck drilling cycle is a critical technique in CNC machining, especially for creating deep, precise holes while managing chip evacuation and tool longevity. Unlike standard drilling, which involves continuous cutting, peck drilling breaks the process into incremental steps, ensuring efficient material removal and reducing heat buildup. Let’s dive into the details of this essential cycle. What is…

If you’ve ever wondered how complex, intricate parts like turbine blades, automotive components, or medical devices are manufactured with such precision, the answer often lies in 5-axis CNC machining. But what exactly is it? And why does it matter if you’re not a machinist? Let’s break it down into simple terms. What is 5-Axis CNC Machining? CNC stands for Computer Numerical Control, which…

The macro language is a programming language that gives the CNC programmer the ability to write very flexible programs. This is done through the use of variables, mathematical expressions and program flow control statements. The macro language combined with standard G-code programming can create reusable programs much like canned cycles. These programs can do many useful things like custom…
