Additionally, we will explore the reasons behind transitioning from manual milling methods to CNC technology.
Lecture 3: Tools
In Lecture 3, we will focus on the selection and understanding of various cutting tools used in CNC milling operations. You will learn about different tool types, their geometries, and the factors to consider when choosing the appropriate tool for specific machining tasks. We will also cover tool materials, coatings, and tool life management.
Lecture 4: Operations on Milling Machine
This lecture covers the fundamental milling operations performed on a CNC milling machine. We will discuss concepts such as facing, milling slots, drilling, pocketing, and contouring. You will learn about the different tool paths and machining strategies used to achieve desired outcomes. Practical examples and demonstrations will help you grasp these concepts effectively.
Lecture 5: Speed and Feed
In Lecture 5, we will dive into the critical aspects of speed and feed rate calculations for CNC milling. You will understand the importance of optimizing cutting parameters to achieve efficient material removal while ensuring tool longevity. We will cover concepts such as spindle speed, feed rate, and chip load, and how to calculate them for various milling operations.
Lecture 6: Before Programming
Before diving into programming, it is essential to consider certain factors. In this lecture, we will discuss pre-programming considerations, including machine setup, workpiece and fixture considerations, and safety precautions. Understanding these aspects will help you prepare for effective and successful CNC milling operations.
Lecture 7: Cutting Fluid
The effective use of cutting fluid is vital for achieving optimal machining results. In Lecture 7, we will explore the purpose, types, and application methods of cutting fluids in CNC milling. You will learn about the benefits of cutting fluids in terms of cooling, lubrication, and chip evacuation, and understand how to select and apply the appropriate fluid for different machining scenarios.
Lecture 8: G Code
G code is the programming language used to control CNC machines. In this lecture, we will introduce the fundamentals of G code programming for CNC milling machines. You will learn about G code commands for controlling tool movement, spindle speed, feed rate, and other machine functions. Practical examples and exercises will enhance your understanding of G code programming.
Lecture 9: M Code
Complementing the G code, M code commands are used to control auxiliary machine functions during CNC milling. Lecture 9 focuses on the understanding and application of M code commands. We will cover commands for tool changes, coolant activation, machine startup and shutdown, and other critical functions. Practical exercises will solidify your knowledge of M code programming.
 
By the end of this course, you will possess a comprehensive understanding of CNC milling machine programming. You will be equipped with the skills needed to select the appropriate tools, perform essential milling operations, calculate speed and feed rates, consider pre-programming factors, apply cutting fluids effectively, and program using G and M codes.
