Program Overview:

LATTC has one of the most spacious and well equipped Machine Shops of any of the community colleges in the nation!  Come check us out our non-traditional program for men and women and begin learning to earn in this profession.

Machinists use machine tools, such as lathes, milling machines, and machining centers, to produce precision metal parts.  They use their knowledge of the working properties of metals and their skill with machine tools to plan and carry out the operations needed to make machined products that meet precise specifications. Many modern machine tools are computer numerically controlled (CNC). CNC machines, following a computer program, control the cutting tool speed, change dull tools, and perform all of the necessary cuts to create a part. Frequently, machinists work with computer control programmers to determine how the automated equipment will cut a part. The programmer may determine the path of the cut, but the machinist determines the type of cutting tool, the speed of the cutting tool, and the feed rate. Because most machinists train in CNC programming, they write basic programs and often set offsets (modify programs) in response to problems encountered during test runs.  Because the technology of machining is changing rapidly, machinists must learn to operate a wide range of machines. Along with operating machines that use metal cutting tools to shape work pieces, machinists operate machines that cut with lasers, water jets, or electrified wires. As engineers create new types of machine tools and new materials to machine, machinists must constantly learn new machining properties and techniques.  Los Angeles Trade Technical College offers an Associate of Science Degree in Machine Shop CNC (Core major plus general education classes) or a Certificate of Completion (Core major only no general education classes). Additionally we offer a Certificate of Completion – Adjunct in Machine Shop CNC.  What is the difference you ask?  The Associate of Science Degree or equivalent Certificate of Completion is designed for day time implementation and for people that are looking to make first entry into the field.  A student taking the programs must be able to commit to fulltime student status which is approximately 21 hours per week.  This commitment in time is required to allow for hands on training in laboratory applications that are utilized during the course of instruction.  The Certificate of Completion- Adjunct is designed for evening implementation and for individuals that are currently in the field and looking to improve their skills or learn new ones. Limitations on available evening hours restrict the utilization of extensive hands on laboratory practices and the hands on application is assumed to happen at the students place of employment.

Industry Information:

Machinists held about 370,000 jobs in 2006. Most machinists work in small machining shops or in manufacturing industries, such as machinery manufacturing and transportation equipment manufacturing (motor vehicle parts and aerospace products and parts). Maintenance machinists work in most industries that use production machinery.

Despite relatively slow employment growth, job opportunities for machinists should continue to be good. Many young people with the necessary educational and personal qualifications needed to obtain machining skills often may not wish to enter production occupations. Therefore, the number of workers obtaining the skills and knowledge necessary to fill machinist jobs is expected to be less than the number of job openings arising each year from the need to replace experienced machinists who transfer to other occupations or retire, and from job growth.
