3 Session Class

Session A: Milling Basics

Wednesday, June 2, 2021, 6:00 PM - 9:00 PM

INTRODUCTION OF MILLING BASICS

  • Teach students about the industry of Manual and CNC Machining and manufacturing and the applications of the trade.
  • Demo the differences between manual and CNC machines and what their strengths and weaknesses are.
  • Discuss exploded views of a milling machine, use videos if needed, showing drives, ways, ball screw, and spindle
  • Use of basic measuring tools
  • Show students about basic cutting tools and their applications.
  • Discuss feeds and speeds, Climb and Conventional
  • Allow student to set up block of aluminum and make X & Y cuts
  • Teach students basic metal cutting principles on the manual machine which will translate to CNC

PROJECT BASED STEPS

  1. Use Horizontal band-saw to cut stock to rough length
  2. Properly load part into milling vise
  3. Load a cutting tool into a Bridgeport
  4. Machine block to a specified length.
  5. Measure block to verify machining was correct.

Session B: HAAS CNC Milling Fundamentals

Wednesday, June 9, 2021, 6:00 PM - 9:00 PM

INTRODUCTION TO THE HAAS MILL

  • Understanding the HAAS interface and button layout
  • Review exploded views of the machine and understand it’s operation
  • Setting tools, loading the carousel
  • Learn about 123 blocks and manual probe
OPERATION
  • Compressor room, air dryer, power up and down, Emergency stops, resets
  • Feeds and speeds and jog dial control
  • Visual pre-flight, clean up
RUNNING A PART
  • Look at a (1M) part on a computer in Solidworks or Mastercam - export CAM G-code
  • Load a pre-designed program in the simulator
  • Study lines of G-code and look for XYZ movements and tool changes
  • Understand where and how the machine might crash based on code and simulation
  • Loading material, hold-downs, vices, torqueing
  • Use probe to touch off top and sides of material stock
  • Only instructor runs a demo of part 1M on the HAAS
  • Shut down, cleanup

UPON COMPLETION of Session B MEMBERS WILL MOVE TO A SERIES OF HOMEWORK VIDEOS TO BE WATCHED BEFORE MOVING TO SESSION #

Session C: HAAS CNC Milling Operation

Wednesday, June 16, 2021, 6:00 PM - 9:00 PM

RUNNING A PART ON THE HAAS MILL

  • Each student will load a program on the HAAS simulator and complete the following:

  • Study lines of G-code and look for XYZ movements and tool changes

  • Tapping? - optional

  • Understand where and how the machine might crash based on code and simulation

  • Instructor assures machine will not crash and offers useful criticism on adjustments

  • Understand feeds and speeds

Load milled block from class (1 of 4) Each student will go through this process:

  • Power up

  • Load tools

  • Tapping? - optional

  • Use probe to touch off top and sides of material stock

  • Each student runs a demo of part 1M on the HAAS

  • Instructor assures machine will not crash – offers feeds and speeds advice

  • Shut down, cleanup
