A CNC machining centre goes down at 2pm on a Wednesday. Nobody is surprised — it has been making a noise for three days. The maintenance team is called, the part takes four days to arrive from Germany, and the machine is down for a week. Three production orders miss their delivery dates. Two customers are unhappy.
The machine noise was a symptom. The root cause is that there was no scheduled maintenance programme, no inspection history, and no parts inventory for this machine. The failure was predictable and preventable. The week of downtime was not.
Machine maintenance and asset management in manufacturing ERP does not prevent all equipment failures. It prevents the predictable ones — the ones caused by neglect, deferred servicing, and the absence of systematic inspection.
Preventive Maintenance Scheduling
Preventive maintenance is maintenance performed at defined intervals regardless of whether the equipment shows signs of failure. The interval is based on the manufacturer's recommendation (time-based: every 500 hours, or every 6 months), on actual usage (production-based: every 10,000 cycles), or on condition monitoring data (condition-based: when vibration exceeds a threshold).
A maintenance scheduling system:
Generates work orders automatically. When a machine approaches a maintenance interval, the system creates a maintenance work order — what is to be done, what parts are required, which technician is assigned, and by when. The work order is scheduled around production to minimise disruption.
Tracks maintenance history. Every maintenance event — scheduled or breakdown — is recorded against the machine record. The history shows what was done, when, by whom, what parts were used, and how long the work took. This accumulates into a maintenance log that supports warranty claims, insurance assessments, and machine disposal decisions.
Manages maintenance parts inventory. Critical spare parts — those with long lead times or high failure impact — can be held in a maintenance parts store and tracked through the system. When a maintenance work order is raised, the required parts are reserved from stock. Parts usage is tracked, and reorder points trigger replenishment automatically.
Monitors downtime. When a machine breaks down, the system records the breakdown time, the cause, and the time to restore. Unplanned downtime by machine, by cause category, and by month accumulates into data that shows where the maintenance programme needs attention.
Asset Register and Lifecycle Management
An asset register is a record of every significant piece of equipment in the business: machine ID, description, manufacturer, model, serial number, purchase date, purchase cost, location, current condition, and maintenance history.
Most Singapore manufacturers have some version of this — often a spreadsheet that was accurate when it was created and has been partially maintained since. The problem with a spreadsheet asset register is that it is disconnected from the maintenance schedule, the parts inventory, and the production system. When a machine needs a part, someone has to look up the machine record separately to find the model number.
An asset register within the manufacturing system connects the machine record to everything related to it: the production orders that use it, the maintenance schedule, the parts inventory, the breakdown history, and the operator certifications required to run it.
Depreciation tracking. The system calculates and records annual depreciation for each asset using the elected method (straight-line or reducing balance). This feeds directly into the management accounts without a separate calculation. For Singapore manufacturers who claim capital allowance under the Income Tax Act, the asset record provides the data needed for the CA claim.
Asset disposal and write-off. When a machine is sold, scrapped, or written off, the system records the disposal, calculates the gain or loss on disposal, and removes the asset from the depreciation schedule. The maintenance history and total lifetime maintenance cost are preserved in the archive.
Warranty tracking. New equipment typically carries a manufacturer warranty. The system records the warranty expiry date and flags when a maintenance event would be covered under warranty versus when it should be charged to the business. Claims against warranty require documentary evidence; the maintenance record provides it.
Overall Equipment Effectiveness (OEE)
OEE is the standard metric for measuring manufacturing equipment productivity. It combines three factors:
- Availability — the percentage of scheduled production time the machine is actually available (not in breakdown or maintenance)
- Performance — the actual output rate as a percentage of the theoretical maximum rate
- Quality — the percentage of output that meets specification without rework
OEE = Availability × Performance × Quality
World-class OEE is typically cited as 85% or above. Most manufacturers who measure it for the first time find they are in the 40-60% range — not because the machines are bad, but because the losses were never systematically visible.
A manufacturing system that captures machine downtime (from maintenance records and production records), actual versus planned output rates (from production records), and defect rates (from quality records) can calculate OEE by machine and by period without manual data compilation.
OEE is most useful as a trend metric and a prioritisation tool. A machine with consistently low OEE is a bottleneck that deserves investment — in maintenance, in process improvement, or in replacement. OEE data makes this investment decision evidence-based.
Maintenance in the Singapore Manufacturing Context
Singapore manufacturers face specific maintenance considerations:
High equipment utilisation. With expensive floor space and high labour costs, Singapore manufacturers typically run equipment at high utilisation rates. High utilisation compresses the maintenance windows and accelerates wear. Preventive maintenance must be scheduled precisely to avoid production disruption.
Skilled maintenance technicians. Specialist maintenance skills — CNC calibration, pneumatics, hydraulics, electronics — are in short supply in Singapore. Maintenance scheduling that optimises technician time and avoids emergency callouts is valuable in a tight labour market.
Import lead times for parts. Replacement parts for European or Japanese equipment often have 1-4 week lead times from Singapore. Critical spare parts should be held locally; the maintenance system should flag which parts are critical and ensure they are stocked.
Equipment age. Many Singapore SMB manufacturers run equipment that is 10-20 years old. Older equipment has higher failure rates and more complex maintenance requirements. The maintenance record for an ageing machine is also important documentation if the business is considering replacement — it shows the real cost of keeping the old machine running.
When Maintenance Management Matters
The signal is usually a breakdown that caused a significant production disruption, or a pattern of "fires" that the maintenance team is always fighting rather than preventing.
The investment in a maintenance management system pays back quickly when the business can quantify the cost of unplanned downtime — hours lost, jobs delayed, overtime incurred, customer relationship impact. For most Singapore manufacturers with significant equipment investment, even one prevented major breakdown per year more than justifies the cost of a maintenance management module.
