Managing a Machine Operator in ZeniaHR

AttendanceMachine operators work fixed or rotating shifts set in the roster and punch at the gate biometric over ADMS. Mark night shifts so hours file to the right day, and use the [attendance rules](/hrms/features/attendance/) so late marks and penalties are applied fairly.LeaveKeep enough trained operators on each machine when approving leave, as an idle machine loses the shift quantity. The leave calendar shows booked days, and weekly offs worked during a push earn comp-off granted by HR.Performance and KRAsDuring probation the supervisor records a probation review rated 1 to 5 on output, quality and discipline. After confirmation, set output and quality as goals in a monthly or quarterly review cycle with a rating scale.

Frequently asked questions

What does a machine operator do?

A machine operator runs an assigned production machine through the shift. They load and unload the job, run it to the set method, make basic quality checks, and keep output to target. They spot machine and quality problems early, do daily start-up checks, and keep the station clean and safe under 5S.

What is the difference between a machine operator and a CNC operator?

A machine operator runs a production machine to a set method and manages loading, output and basic quality. A CNC operator runs a computer controlled machine, which adds loading programs, setting tool and work offsets, and adjusting for tool wear. The CNC role usually needs more skill in measurement and controls.

What qualifications do you need to be a machine operator?

Most machine operators hold an ITI or a tenth pass and learn the machine on the job. Employers look for the ability to follow a process sheet, make basic quality checks with a vernier or gauge, do daily machine checks, and work safely. Reliability and steady attendance are valued because idle machines lose output.
