A precision machining company serving the aerospace and defense sector is adding a senior CNC Programmer to its Glen Burnie shop. This is a hands-on programming seat covering the full shop: 2-3 axis mills, mill-turn and live-tooling lathes, and 3+2 indexed multi-axis mills, all programmed in Mastercam 2025. You take parts from print to verified, production-ready NC code, and you are the go-to person when a setup gets complicated.
WHAT YOU WILL DO
Program parts in Mastercam 2025 across 2-3 axis mill, lathe/mill-turn (live tooling and sub-spindle transfer) and 3+2 positional multi-axis work, picking the right process for each part
Read engineering prints including GD&T and turn tolerance and finish requirements into sound toolpath, tooling and workholding decisions
Plan workholding and setup sequencing (multi-setup mill parts, sub-spindle transfer, indexed orientations) to control cost, cycle time and stacked location error
Select tooling, feeds and speeds for the material and operation instead of relying on defaults
Verify programs in solid and machine simulation (fixture, holder, turret and trunnion models) before release to the floor
Maintain and troubleshoot post processors and control definitions; root-cause posted-code issues such as rotary axis output, canned-cycle mismatches and offset errors
Write clear setup sheets: tool lists, work offset and plane assignments, setup notes
Support first-article runs and troubleshoot in-process issues (chatter, finish, thread fit, transfer marks)
Drive cycle time reduction and repeatability on running production jobs
WHAT YOU NEED
5+ years of CNC programming, hands-on with Mastercam (2025 or recent versions)
