Criticality before frequency
Maintenance effort should reflect what the asset does to safety, quality, throughput, labour, delivery, and recovery time—not simply how old the machine is.
Titan helps manufacturers build maintenance programs around real assets, actual production criticality, OEM requirements, safe work preparation, condition monitoring, spare-parts readiness, CMMS discipline, planned shutdowns, controlled return to service, and the recurring failures that consume capacity.
Reactive repair begins after the production consequence has already arrived. Planned maintenance starts earlier: the asset is identified, its criticality is understood, likely failures are evaluated, the correct task and trigger are selected, parts and labour are prepared, the production window is coordinated, and the machine is returned to service through a defined acceptance process.
Titan’s framework connects operators, maintenance, production, engineering, purchasing, software, tooling, dust collection, utilities, service providers, and management. Exact tasks, intervals, lockout procedures, inspection methods, and repair requirements remain governed by the machine manufacturer, qualified personnel, the employer’s safety program, and applicable regulation.
Maintenance effort should reflect what the asset does to safety, quality, throughput, labour, delivery, and recovery time—not simply how old the machine is.
OEM manuals, service bulletins, machine configuration, serial number, software version, and qualified service requirements form the starting point for every task and interval.
Lockout, stored-energy control, safeguarding, access, permits, and authorized personnel must be planned before tools, parts, or labour are scheduled.
A maintenance window should begin with approved scope, labour, parts, tools, procedures, access, backups, test material, and return-to-service criteria ready.
Inspection, alarms, vibration, temperature, pressure, vacuum, lubrication, cycle time, quality, and component usage can reveal degradation before a calendar date does.
Critical spares, wear items, consumables, repairables, long-lead components, and approved alternates need ownership, location, reorder logic, and condition control.
Repeat alarms, emergency repairs, rework, service notes, operator observations, and replaced components should feed back into task content, frequency, training, and design changes.
A repair is not complete until safeguards, settings, lubrication, utilities, tooling, software, documentation, first-piece quality, and production handoff are verified.
A mature program does not force every asset into the same calendar-based schedule. The strategy should match criticality, failure behaviour, detectability, production consequence, data quality, and recovery readiness.
Used deliberately for low-criticality items where failure has limited safety, quality, production, or repair consequences.
Tasks performed at fixed calendar intervals based on OEM guidance, regulation, environment, or known degradation.
Maintenance triggered by hours, cycles, panels, metres, shifts, tool changes, or production campaigns.
Work initiated from measured or observed condition such as differential pressure, vibration, temperature, vacuum, current, wear, or quality drift.
Models or trend analysis estimate when performance thresholds may be exceeded so work can be scheduled before functional failure.
Focuses on root causes such as alignment, balance, contamination, fastening, installation, lubrication, heat, dust, or operating practice.
Concentrated work completed during a planned outage with coordinated production, contractors, parts, testing, and restart.
Uses criticality, failure modes, history, economics, and engineering changes to reduce recurring loss rather than repeatedly servicing symptoms.
The audit can cover one asset, one production cell, or a plant-wide hierarchy that connects primary machines, automation, dust collection, utilities, software, tooling, and support systems.
Spindles, tool changers, vacuum systems, lubrication, linear guides, drives, sensors, dust boots, aggregates, controllers, backups, geometry, and machine-specific service intervals.

Drill banks, insertion heads, glue systems, nozzles, clamps, fixtures, feeders, sensors, depth control, cleaning, and spare wear components.
Fans, drives, filters, differential pressure, cleaning systems, ducts, gates, discharge, bins, fire protection, controls, and housekeeping interfaces.
Lifts, conveyors, returns, robots, storage systems, stops, sensors, guarding, interlocks, alignment, chains, belts, rollers, and recovery procedures.
Compressors, dryers, vacuum pumps, chillers, electrical distribution, networks, UPS systems, lubrication systems, and environmental controls.
Machine backups, PLC/HMI versions, parameters, post processors, tool libraries, recipes, licences, network dependencies, cybersecurity, and restore procedures.
Fixed preventive tasks remain important, but critical equipment can also benefit from usage-based triggers, inspections, alarms, vibration, temperature, vacuum, pressure, differential pressure, quality trends, and component-health information. Condition monitoring should be adopted only when the measurement is trustworthy, the response is defined, and the avoided consequence justifies the effort.
Clarify whether the project addresses emergency downtime, a new maintenance program, aging equipment, a shutdown, parts shortages, recurring quality loss, new-machine handoff, CMMS implementation, or a reliability-improvement campaign. Establish the production, safety, quality, labour, and financial outcomes the program must support.
Create a controlled record for each asset and maintainable subsystem. Capture manufacturer, model, serial number, age, location, production role, utilities, controls, software version, connected equipment, manuals, warranty, service contacts, responsible owner, and current status.
Evaluate the consequence of failure rather than using one maintenance level for every machine. Consider worker safety, environmental or fire exposure, product quality, bottleneck effect, redundancy, work-in-process, customer delivery, repair complexity, spare-parts lead time, and the time required to restore stable production.
Assemble manuals, lubrication charts, service bulletins, electrical drawings, pneumatic or hydraulic diagrams, backups, parameter files, alarm history, prior work orders, invoices, replaced-part history, inspection records, and operator observations. Record current performance baselines before changing the program.
Break each critical asset into maintainable functions and ask how it can fail, what causes the failure, how the condition becomes visible, what consequence follows, and which task can prevent, detect, contain, or recover from it. Separate functional failure from minor defects that do not justify the same response.
Define the safe state, energy-isolation requirements, stored-energy controls, guarding, access, permits, lift or platform needs, hot-work implications, environmental conditions, and qualifications required before a task is scheduled. Work requiring energized diagnostics or specialized service needs approved procedures and authorized personnel.
Choose the least-complex strategy that controls the failure risk. Some tasks belong on fixed intervals; others should follow usage, measured condition, inspection findings, production campaigns, or a planned shutdown. Low-criticality components may be intentionally run to failure when the consequence is acceptable and recovery is ready.
Identify the measurements and observations that reveal degradation early enough to act. Useful indicators may include vibration, temperature, noise, motor current, vacuum, air pressure, differential pressure, lubricant condition, contamination, leakage, wear, backlash, geometry, cycle time, alarms, tool life, and first-pass quality.
Convert recurring work into controlled job plans with task scope, prerequisites, estimated duration, labour skills, parts, consumables, tools, drawings, isolation references, access, photos, measurements, acceptance criteria, cleanup, and return-to-service requirements. Avoid turning a work order into an unstructured note.
Classify parts by production consequence, lead time, failure pattern, repairability, shelf life, storage needs, value, and interchangeability. Record exact machine compatibility, approved alternates, reorder points, min/max quantities, repair rotation, and the condition of stored components.
Use a CMMS, ERP maintenance module, or disciplined work-order system to connect assets, tasks, parts, labour, inspections, failure codes, documents, schedules, and costs. Keep the structure usable enough that technicians and supervisors can record meaningful completion data during real production pressure.
Separate planning from scheduling. Planning makes the job ready; scheduling assigns ready work to a realistic production window with available labour, parts, permits, access, contractors, and expected duration. Protect a frozen weekly schedule while retaining a controlled path for true emergencies.
For major maintenance days, create one integrated outage plan with scope ownership, sequence, isolation boundaries, contractor coordination, parts staging, tools, lifts, work areas, progress reviews, quality hold points, change control, cleanup, testing, and restart authority.
Verify that tools and foreign material are removed, guards and safety devices are restored, fasteners and connections are complete, lubrication and utilities are correct, alarms are cleared appropriately, backups or parameters are current, and the approved test plan is ready. Production release should include a controlled functional test and first-piece or process validation.
Use a limited set of measures that reveal whether the program is becoming more planned, more reliable, and easier to execute. Review emergency work, preventive compliance, schedule compliance, repeat failures, backlog age, parts stockouts, mean time to repair, availability, first-time fix, and production loss.
Update tasks, intervals, spares, training, drawings, backups, risk controls, and reports when failure evidence supports a better method or when equipment, materials, software, production rate, dust collection, guarding, utilities, or workflow changes. Reliability improvement should remove causes, not merely shorten the response to the same failure.
Actual tasks and intervals must follow OEM requirements, asset duty, environment, history, regulation, condition, and qualified review. This cadence is a planning framework, not a universal service schedule.
Visual condition, leaks, unusual sound or heat, guarding, air and vacuum status, dust accumulation, tool or consumable condition, alarms, cleaning, and abnormal-operation handoff.
Lubrication-system status, filter or pressure indicators, coolant or glue condition where applicable, machine cleaning, tool-change areas, safety devices, production faults, and open work requests.

Selected geometry, vibration, thermal, electrical, lubrication, vacuum, pressure, calibration, drive, safety, and control-system checks based on the asset plan.
Comprehensive asset audit, major service tasks, critical-spares review, software and backup validation, safeguarding review, condition baselines, and next-year shutdown plan.
Major inspection, rebuild, alignment, controls work, dust-system service, utilities, guarding, structural work, deep cleaning, validation, and coordinated restart.
Monitoring becomes valuable when the point, method, operating condition, baseline, threshold, owner, and required response are defined.
Bearings, spindles, fans, pumps, gearboxes, motors, and rotating assemblies can be trended for changes that justify inspection or planned intervention.
Temperature patterns can reveal electrical connection problems, overloaded components, lubrication issues, friction, cooling loss, or process conditions requiring qualified review.
Motor current, drive alarms, torque, load, starts, power quality, cabinet temperature, and fault history can support diagnosis when interpreted against normal operation.
Oil, grease, coolant, glue, hydraulic fluid, and compressed-air condition require correct product, cleanliness, quantity, interval, storage, and contamination control.
Vacuum pumps, compressed air, dust collection, cooling, glue delivery, pneumatics, and hydraulics can be monitored for leakage, restriction, loading, or declining performance.
Backlash, calibration, tool-change repeatability, saw alignment, drilling position, sanding calibration, profile accuracy, and first-pass quality can reveal mechanical drift.
Differential pressure, cabinet cleanliness, fan loading, machine dust accumulation, sensors, cooling passages, and contamination often influence component life and reliability.
Alarm frequency, program changes, communication faults, restart time, cycle-time drift, and operator workarounds can expose control, process, or training problems.
Stocking everything is expensive; stocking nothing transfers the cost to downtime. The useful middle ground is an asset-linked, criticality-based inventory with exact compatibility and known replenishment paths.
Components whose absence would create unacceptable downtime, safety exposure, or loss of the only production route.
Belts, pads, seals, filters, hoses, brushes, scrapers, bearings, chains, inserts, and other items consumed through predictable service.
Lubricants, cleaners, coolants, adhesives, filter media, fasteners, batteries, fuses, and task-specific supplies.
Motors, pumps, drives, spindles, gearboxes, electronics, or assemblies managed through exchange, rebuild, or repair loops.
Legacy controls, custom assemblies, imported components, or discontinued items requiring contingency, retrofit, or replacement planning.
Validated substitutes, service kits, task kits, and machine-specific groups that reduce search time and incomplete maintenance jobs.
The strongest shutdown plans coordinate production release, isolation, contractors, parts, tools, lifts, access, drawings, backups, removed components, scope changes, progress control, cleanup, testing, first article, and restart authority. A machine being available is not the same as the maintenance work being ready.
The expensive part of many failures is not the component. It is the production interruption, diagnosis time, unavailable information, missing parts, repeated repair, and unstable restart that surround it.
A planned maintenance day started with the machine available but the job plan did not include exact seals, fasteners, lubricant, access tools, or a replacement sensor. Technicians discovered missing items after disassembly, extending the outage into the next production shift.
A recurring bearing failure was treated as a component problem. The actual contributors included contamination, installation condition, alignment, loading, and weak lubrication control. Replacing the bearing restored production briefly but preserved the failure mechanism.
Cooling passages and cabinet filters loaded gradually. Drives and controls began showing intermittent temperature-related alarms, leading to repeated resets and electronics troubleshooting while the underlying airflow condition remained.
A control component failed and the team had an old backup, but the machine configuration, software version, passwords, parameters, and restoration path were incomplete. Mechanical repair finished before the control system could be returned to production.
A high-value spare was stocked for years but had never been checked against the machine serial number and installed options. When needed, the connector and firmware did not match the actual machine configuration.
Work orders were closed on time, but tasks consisted mainly of generic inspection statements. Measurements, findings, replaced parts, failure codes, and corrective actions were not recorded, so repeat defects remained invisible.
Share of maintenance labour completed from prepared work rather than emergency response.
Scheduled preventive tasks completed within the approved tolerance window.
Weekly scheduled work completed as planned, with reasons recorded for deferrals.

Operating time or production between defined functional failures for a selected asset.
Elapsed repair or restoration time from approved start point to defined return-to-service condition.

Assets, goals, sites, roles, production windows, current problems, and decision authority are clear.
Asset register, OEM information, criticality, isolation needs, guarding, access, and qualified-work requirements are documented.
Failure modes, tasks, triggers, intervals, condition points, and run-to-failure decisions have owners and evidence.

Scope, parts, labour, permits, isolation, access, test materials, restart plan, and contingency have passed readiness review.
Mechanical, controls, safety, documentation, functional test, first-piece quality, and operator handoff are complete.
Metrics, backlog, spares, training, audits, change control, and improvement ownership are active.
Requirements and software capabilities change. The project team should confirm the current manufacturer documentation, regulation, software version, and authority requirements for the exact machine and location.
