Virtual SkillsUSA CNC Milling Specialist Project
Scope of the Contest
The purpose of this contest is to evaluate each contestant’s preparation for employment in Computer Numeric Control Milling. In
addition, to recognize outstanding students for excellence and professionalism.
Skill Performance
The contest will assess the ability to write CNC programs, interpret prints (including GDT), and measure/gauge parts. Participants also
will demonstrate theoretical knowledge of CNC machine configuration, setup and operations.
Contest Guidelines
1. Each contestant will be given dimensional drawings to program a part on a Haas CNC Controller.
2. Programming
a. Write and verify CNC programs without the use of CAM software
b. Display complete knowledge of programming (G and M codes)
c. Apply the correct use of cutter compensation (G41/G42)
3. Perform mathematical calculations
a. Calculate CNC speeds and feeds
b. Calculate programming coordinates from the drawing
c. Calculate radius tangent points
4. Measuring
a. Measure sample parts within 0.005"
5. Communication
a. Read and interpret technical prints
b. Understand all symbols on technical prints, such as geometric controls, surface-finish symbols, corner-break symbols, etc.
6. Dimensions
This is a contest of programming skills. Contestant parts will only run on machine if programs run without violating safety standards
or damaging machines.
2021 SkillsUSA 10 of 10
Knowledge Performance
The contest will include a Resume, Portfolio, and Pre-Recorded Video.
Contest Information (All items must be received by March 26)
● PDF Resume
o Upload one file with contestant’s one-page resumes and include the digital link(s) to Written Outline and the pre-recorded video through Teams/ Zoom.
● Written Portfolio to include: o Written outline that identifies the process used including safety guidelines to create the completed project. Identify time
management and technical skills demonstrated.
● Video of Demonstrated Procedures
o Launch a Zoom/Teams Session and join in with the computer being used by contestant, and one to two additional cell-phone or web cameras showing the contest up close and one at a distance to show the lab space. Make sure the zoom in on the contestant’s hand as he/she is programming the CNC trainer. Contestant should narrate what they are doing while they are doing it to ensure the judge can see/hear that they are following the proper sequence.
*Consider Safety when placing your camera(s).
o Record the entire demonstration without edits. Record the entire process in one unedited recording session.
*Video submission should be linked into the PDF file resume.
Scoring Information
The following pre-submission items will be judged by industry professionals.
