A CNC machining center requires a program to maximize the machine’s capabilities. Creating a CNC program is only performed after a careful planning stage to determine exactly what machining operations and which part dimensions the CNC machining center will need to machine.

Learning Objectives

  • Define a CNC program
  • Define the steps in CNC programming
  • Understand the importance of thoroughly planning the creation of a CNC program 
  • Define program zero
  • Distinguish between machine zero and program zero
  • Explain the relationship between work offsets, machine zero, and program zero
  • List methods of creating a CNC program

A CNC machining center program is required to be organized in a specific manner for the controller to understand the instructions within the program. Each instruction must also be organized.

Learning Objectives

  • Define a stop code
  • Define an end of block symbol
  • Understand the use of parentheses in a CNC program
  • List the two sections of a CNC machining center program
  • Distinguish between a block and a word
  • Understand the purpose of the program end function

The address of a word in a CNC machining center program defines the meaning of the word. Understanding the meaning of common words in a CNC program is important to recognize what actions the CNC machine tool will perform.

Learning Objectives

  • Define the purpose of G codes
  • Define the purpose of S, T, and M words
  • Understand the importance of G code groups
  • Define the meaning of common G codes
  • Define the meaning of common M words
  • Understand the numeric value of a T word
  • Understand the importance of the format of the numeric data in a word

The instructions written in G code programming that produce an action by a vertical CNC machining center are called commands. A command may require a single word, a block, or multiple blocks.

Learning Objectives

  • Understand the requirements to command a tool change function
  • Understand the requirements to command a spindle function
  • Understand the requirements to command a linear movement
  • Understand the requirements to command a circular movement
  • Understand the requirements for canned cycle commands

Building a CNC machining center program that is versatile requires organizing sections into an order that will safely produce a part that meets all of the part’s requirements.

Learning Objectives

  • List common commands used in each section of the body of a CNC program
  • Define a safe start block
