Introduction to CNC Milling with Austin

Non-Members $399 / Members $299

3 Session Class

Session A: Milling Basics

Wednesday, September 8, 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, September 15, 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

• Compressor room, air dryer, power up and down, Emergency stops, resets
• Feeds and speeds and jog dial control
• Visual pre-flight, clean up

• 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, September 22, 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
