Wi-Fi enabled laptop with USB-A port or adapter and pre-installed CAM software. b. CAD/CAM software (Fusion 360 or Mastercam). Software must be installed prior to arriving at the competition. c. Mastercam, Fusion 360 must have tool path program operation verification simulation software installed and operational prior to arriving at the competition. d. Simulation Software (Vericut). This software is strongly recommended to learn and use for code verification, but not mandatory. e. CAD/CAM software Post-Processor must be compatible with competition CNC machine(s). f. USB 2.0 or 3.0 Flash Drive (8GB or greater). Tape a white label to your USB Flash Drive with your contestant number written with a pen. The contestant number is also used as the file name for the competitor’s submitted CAM files within the Flash Drive. g. Bring a 6’ foot minimum length 3 prong 110V extension cord and surge protector. h. Computer Mouse (3-D mouse allowed) i. 0-1.0” micrometer, 6” caliper (digital or dial), Hand-held scientific calculator, Two Sharpened Pencils, Blank paper, Machinist Handbook (optional), Deburring tools (files, Emory cloth, etc.) Purpose: To evaluate each contestant’s preparation for employment in Computer Numeric Control machining. To recognize outstanding stu- dents for excellence and professionalism in the CNC machining field. Scope of Contest: Each contestant will receive a dimensioned drawing and material to CNC mill a part. Participants are expected to create CNC milling programs using CAM software, execute CNC milling programs with a post-processor compatible with CNC Mills, perform G-Code troubleshooting, set up the machine and tool offsets, and mill a part. Competitors are encouraged to verify tool paths prior to NC file generation using CAM Software or Vericut. Participants are given 15 minutes to study the task and ask questions before beginning. The competition may run 6-8 hours, depending on the project design. Programs that do not run due to errors will receive no points; placement will be based on district scores. Completed Parts will be inspected by judges and scored, any ties will be broken using district scores. Competencies: : 1. Programming a. Create and verify CNC program using CAM software and generate NC file(s) to load in HAAS CNC Mill. b. Tool List(s) (Tool sets provided to competitors and competitor build tool library(s) within CAM software) c. Setup sheet(s) d. Process plan (Job Plan) Online Online Resumé Resumé Submission Submission
