Learn to be a Automotive Engine/Cylinder Head Machinist
The objective of Automotive Engine/Cylinder Head Machining is to qualify the student as an automotive cylinder head machinist. The theory of operation and the cylinder head role in the engine operation will be thoroughly covered. Air flow characteristics and their effect on performance and longevity will be highlighted in all courses of this program.
One semester credit hour for each fifteen (15) hours of classroom contact plus appropriate outside preparation or the equivalent: or one semester credit hour for each thirty (30) hours of laboratory work plus appropriate outside preparation: or one semester credit hour for not fewer than forty-five (45) hours of shop instruction (contact hours) or the equivalent.
Single subjects making up this program are not offered individually. See the Equipment List Addendum for a complete list of machines used in the Automotive Engine/Cylinder Head Machining program.
This course provides a general introduction to the industry work environment including customer relations, work orders, build-sheets, and parts acquisition. Introduction to, and familiarization with the use of precision measurement and specialized, as well as, basic hand tools required will also be covered. Special emphasis is placed on both personal and shop safety due to the nature of potentially hazardous equipment.
The procedures of careful inspection and precise measurement technologies are taught. Combining this information, with the proper applications, formulas, and machinist math will be covered to provide a solid basis for successful production and high performance engine assembly procedures
This course starts with exploring the basic theory and concepts of internal combustion engine operation. The course then moves into more specific and complex areas including torque, air flow, volumetric efficiency, operating cycles, and horsepower
The course explores the hows and whys of the many components of the cylinder head assembly and their relationship to each other.The function and various material compositions of cylinder head castings and components will also be covered. Standard and high performance differences will be discussed.
This course covers the proper procedure of head disassembly and careful inspection to determine any causes of failure, repairs needed, and component replacement. Cleaning methods, crack detection, repair, and associated environmental issues, for both aluminum and iron heads will also be discussed.
The student learns the set-up and operation procedures of machining equipment. He will also learn the procedures used to complete the machining of cylinder heads and component parts. A discussion of high performance and production differences will complete this section.
Actual hands-on cylinder head and component machining will be accomplished by each student as they become proficient with all machining operations. Machined components will be checked closely for accuracy. These pieces will become part of each student’s course project.
Students are exposed to the art of creating maximum efficiency and horsepower through precision component assembly relationships. Combustion chamber sizing and compression ratios will be discussed. Students will also study cylinder head performance secrets.
Correct assembly procedures of the precisely machined components into a complete cylinder head is covered in detail. Evaluation and testing of complete assemblies will reveal the relationship of changes to performance.
Students will explore flow characteristics of various head designs and the resultant effects of change. Proper techniques of porting, when it should be used, and actual hands-on experience will illustrate methods and levels of air flow improvement.
The student is prepared to enter the job market by teaching the importance of personal appearance, conduct, and attitude. Job search, application, and interview are also covered. A brief discussion on career goal orientation and job placement assistance available from the School of Automotive Machinists completes the course.
