CNC Programming Using Fanuc Custom Macro B: A Comprehensive Guide for Engineers and Machinists by S. K. Sinha

Introduction

In the world of precision manufacturing and computer numerical control (CNC) machining, the ability to write efficient, flexible, and powerful programs is what separates a good operator from a great one. CNC Programming Using Fanuc Custom Macro B by S. K. Sinha is a definitive guide for Indian engineers, diploma holders, and machining professionals who want to master the art of macro programming. Published by McGraw-Hill, this hardcover edition is a must-have reference for anyone working with Fanuc-controlled CNC machines, which are widely used across Indian workshops and industries.

Book Overview

This book is a comprehensive resource that takes you from the fundamentals of CNC programming to advanced macro techniques using Fanuc's Custom Macro B language. Unlike standard G-code programming, macro programming allows you to create parametric, reusable, and intelligent programs that can adapt to changing part dimensions, tool wear, and material variations. With step-by-step explanations, practical examples, and real-world programming scenarios, this book equips you with the skills to boost productivity, reduce setup time, and achieve superior accuracy in your machining operations.

Key Highlights

• Focused on Fanuc 0i series controls – the most common CNC platform in Indian manufacturing units
• Hardcover binding for durability in workshop environments
• Practical programming examples that mirror real shop-floor challenges
• Clear progression from basic variables to complex macro calls
• Written by an Indian author with deep understanding of local industry needs

Inside the Book

The book is structured to build your knowledge layer by layer. It begins with an introduction to variables and expressions, then moves into the different types of variables—local, global, macro, and system variables. You will learn how to use macro functions including trigonometric, rounding, logical, and conversion functions. Branches and loops are explained in detail, followed by subprograms and macro call techniques. Each chapter includes programming examples that you can directly apply on your Fanuc-controlled lathes, milling machines, or machining centres.

Key Topics

• Variables and expressions in Custom Macro B
• Local, global, macro, and system variables explained
• Trigonometric, rounding, logical, and conversion functions
• Conditional branches (IF-THEN) and looping (WHILE-DO)
• Subprograms and macro call methods
• Parametric programming for family parts and complex contours
• Error handling and debugging techniques

Reader Benefits

By studying this book, you will gain the ability to write programs that are not only shorter and more efficient but also highly adaptable. You can create custom cycles for drilling, tapping, and pocketing that automatically adjust to different hole sizes or depths. You will reduce manual programming errors, save time during setup, and increase machine utilisation. The knowledge of macro programming also opens doors to higher-level positions such as CNC programmer, process engineer, or production manager.

Learning Outcomes

• Understand the syntax and structure of Fanuc Custom Macro B
• Write parametric programs that use variables instead of fixed values
• Implement conditional logic and loops for repetitive machining tasks
• Create reusable subprograms and macro libraries
• Debug and optimise macro programs for better performance
• Apply macro techniques to reduce programming time by up to 50%

Who Should Read

This book is ideal for CNC operators, programmers, diploma and degree students in mechanical and production engineering, tool room engineers, and workshop supervisors. It is also valuable for entrepreneurs running small to medium-scale manufacturing units who want to enhance their shop's capabilities without investing in expensive CAM software. The language is straightforward and assumes only basic knowledge of G-code programming.
