EST 2050 - Introduction to Lathe Theory


Clock Hours: 72

Delivery Mode
on-ground

Course Description:
This course introduces students to the principles of machine tool theory with an emphasis on conventional and CNC lathe operations.  Students will gain practical experience on real-world assignments using lathes, including the safe and efficient use of grinding machines and a fundamental understanding of metallurgy as it relates to manufacturing systems and tool production.  Students will learn essential lathe operations such as turning (plain, stepped, and tapering), facing, parting off, knurling, thread cutting, grooving, drilling, boring, and reaming.  Attention will be given to setup and alignment of workpieces, proper tool selection and placement, and the mechanics of cutting actions.  Students will learn to distinguish between standard and special-purpose lathes, understand work holding methods (centers and chucks), and develop the ability to analyze, troubleshoot, and solve machining challenges on a lathe.   

Student Learning Outcomes:

  1. Identify and differentiate between conventional and CNC lathe operations, explaining their applications and benefits in modern machining. 

  1. Safely operate an engine lather, following established safety protocols and industry best practices. 

  1. Perform the following essential lathe operations, including plain, stepped, and tapered turning, facing, parting off, knurling, thread cutting, grooving, drilling, boring, and reaming. 

  1. Demonstrate proficiency setting up and aligning workpieces on the lathe using centers, chucks, and appropriate alignment techniques to ensure precision and safety. 

  1. Select and secure cutting tools correctly, ensuring proper positioning relative to the workpiece and understanding the relationship between tool hardness and workpiece material. 

  1. Explain the differences between standard and special-purpose lathes and identify suitable machines for specific operations. 

  1. Understand and apply fundamental principles of metallurgy as they relate to material machinability and tool selection. 

  1. Operate grinding machines safely and effectively as part of the broader machining process. 

  1. Analyze machining operations and troubleshoot common issues, demonstrating problem-solving skills in real-time lathe work scenarios. 

  1. Demonstrate proper use and interpretation of measuring tools and indicators to verify the accuracy and quality of machined components.
