When you've made the choice to develop a training or apprenticeship program, you'll have to spend some time determining the exact goal of your program and how you're going to achieve that goal. Our example is to develop an apprenticeship to build competent setup people.
In the past few months, Shop Talk has reviewed Skill Sets Nos. 1 and 2 and defined these by the specific steps to learn the skills required. Skill Set No. 1 covers fundamental machining knowledge (including shop math, blueprint reading and using measuring equipment). Skill Set No. 2 teaches basic workholding and offsets as well as introducing tooling for lathes and mills.
In Skill Set No. 3, we focus on the additional math, tooling, and processing knowledge required as a prerequisite to editing and writing programs.
IN OUR TRAINING, students on basic G and M codes. I know some people say that you can always look up the codes, but I want people to know the basic codes by heart.
Skill Set No. 3
Speeds and Feeds: Students moving through Skill Set No. 3 need to master calculating speeds and feeds for both mills and lathes. This is an important topic and we should insist that students start their own database. See what works and record the values in a notebook.
Tooling: A student wishing to become a skilled machinist will have a thorough knowledge and understanding of the following tools:
* Boring bars: use and application for both lathes and mills.
* Carbide inserts: understanding how tool nose radius, chip breakers, and grades effect machining
* Insert drills: safe and efficient use
* End mills: knowledge of the types and uses for end mills
* HSS Tooling: drills, taps...
