Preventive maintenance and shop quality · Lesson 2 of 4

Preventive maintenance and shop quality: materials, standards and design constraints

Where maintenance intervals come from, two brake makers' published schedules, the OSHA rules that are inspections, caliper and tape care with a published tape benchmark, traceability, and the AFS limits a quality check uses.

You will be able to: Identify what governs a maintenance plan (the maker's manual, use and climate, OSHA inspection rules), how measuring tools are kept trustworthy, and the AFS limits a quality check measures against.

The manual sets the schedule

RAS, a machine maker, lists the lubricant for each lubrication point of its machines in the operating manual.

Hasty tells folder owners to use the fluid and filter the maker specifies. Accou says to use the oil the press brake maker recommends and never exceed its maximum pressure.

AFS's Thalmann folder follows its own maker's manual, which is not reproduced here.

Glossary

Periodic inspection
The at-least-annual review of an energy control procedure by an authorized employee who does not use it, certified by the employer.
Metrological traceability
Relating a measurement result to a reference through a documented unbroken chain of calibrations.
Zero setting
Closing a clean caliper or micrometer and setting the reading to zero before measuring.
Parallax error
A reading error from viewing a scale at an angle; Mitutoyo reads graduations from directly above to avoid it.
Maintenance and acceptance tolerance
In NIST Handbook 44, the error allowed for a device such as a metal tape, in excess or in deficiency.
