What are the best ways for tracking CapEx in manufacturing?
You can reduce CapEx by fully utilizing existing machines before buying new ones through:
- Real-time machine monitoring and more specifically,
- OEE tracking
- Monitoring downtime
- Having a smart maintenance in place
- Ensuring operator discipline
With profits stretching thin and costs constantly rising, there is always a sense of pressure to produce more on a shop floor. However, to do that, you need to increase capacity. That’s where CapEx tracking comes in — giving you visibility into where money is being spent and whether machines are being used to their full potential.
Let’s give you a scenario. This is the conversation between a plant manager and a supervisor who are running a small automotive unit with 10 CNC machines.
Plant Head: We’ve got 10 CNC machines. Each machine is planned for 20 hours a day, about 600 units per machine. That means 6000 units daily. So why aren’t we hitting that?
Supervisor: Sir, on paper yes, 6000. But in reality, every machine loses 2 hours to breakdowns, 1 hour to shift handovers, and another hour to setup delays. That’s 4 hours gone every day.
Plant Head: So effectively, each machine runs only 16 hours?
Supervisor: Exactly. Which means 16 × 30 = 480 units per machine. Across 10 machines, that’s 4800 units a day.
Plant Head: That’s 1,200 units less than the target. Basically, we are losing the output of two entire machines.
Supervisor: Yes, sir. “Let’s buy two more CNC machines.”
Plant Head: But that’s at least ₹20 lakh in capital expenditure. And we’re already running on tight margins.
Supervisor: Right. So what do we do then?
Plant Head: The smarter move is to recover those 1200 units by reducing downtime, tightening shift handovers and cutting setup time. If we improve OEE, we’ll get the same extra capacity – without spending on new machines.
Supervisor: Makes sense sir. So instead of adding machines, we add discipline, training, and maintenance. Much cheaper, much faster.
Plant Head: Exactly. Better utilization is the real expansion.
Why you should not buy new machines to increase revenue?
Before you spend on new machines, ask yourself this: Are my existing machines giving me at least 70 to 80% of their potential? For most plants, the answer is no. And that’s why capital expenditure isn’t always the best way to increase revenue. In fact, practicing capex freezing (holding off on new purchases until you’ve fully tapped existing capacity) and better asset utilization can give you far better returns. Here’s what you can do:
Track and improve OEE
The best way to measure manufacturing efficiency is through Overall Equipment Effectiveness (OEE). It takes into account three things:
Availability (Is the machine running when it should?)
Performance (Is it producing as fast as it can?)
Quality (Are we making good parts without rework?)
When you multiply these three, you get a percentage — your OEE score. For instance, if your OEE score is sitting at 50 to 60%, that means half your capacity is idle.
It doesn’t end here. OEE shows all your hidden losses (downtime, slow cycles, rework). When operators gain visibility of OEE, excuses come down. People start owning machine performance instead of blaming external factors. It also gives you a standard metric to benchmark across shifts, machines or even plants. In case there is a sudden dip, OEE shows exactly where the problem lies, so that you can fix it instantly.
Monitor downtime
Machines rarely run 100% of the time. You lose hours to:
Unplanned breakdowns
Changeovers
Idle time at shift handovers
This is known as downtime. Why is it important to monitor this? Each 1-hour loss across 10 machines = 10 machine-hours wasted. Over a month, that’s hundreds of lost hours – equivalent to an extra machine’s worth of production.
This is downtime. Why does it matter? Because every 1-hour loss across 10 machines = 10 machine-hours wasted. Over a month, that’s hundreds of hours — equivalent to an extra machine’s worth of production. If you take the necessary steps to reduce downtime, you effectively gain “new machine capacity” without spending a rupee.
Ensure operator discipline and ethics
Let’s be honest: Operator behavior directly impacts manufacturing efficiency. Taking long breaks, fudging downtime logs, or waiting unnecessarily for materials – everything adds up. How can you tackle this?
- Set up a real time monitoring system that tracks data and takes the guesswork out.
- Define standard work hours, breaks and shift handover protocols.
- Recognize and reward operators who consistently meet targets.
- Train them on machine handling, safety, and help them understand the cost of poor ethics.
- Foster ownership by involving them in meetings and decision making
Maintain machines well
Skipping preventive maintenance feels like saving time — until the machine breaks down in the middle of a critical order. On the other hand, over-maintenance also eats into uptime. So smart, scheduled maintenance is the way to go. It helps in effective CapEx tracking and translates to lower repair bills, better asset utilization, and ultimately, capex reduction without compromising output.
How can you freeze CapEx for free?
CapEx freezing is all about sweating the assets before buying new ones. And, the best way to do this is by setting up a real-time machine monitoring software like Leanworx, which makes CapEx tracking easier and give you instant visibility into every machine’s performance.
Many manufacturing plants still depend on operators to make manual notes regarding stoppages, breakdowns or downtime. These often turn out to be subjective, fudged, and reach the management only at the end of the shift. By then, the day’s capacity is already lost. With Leanworx, you can know in real-time as to where exactly the output is slipping. So you can freeze CapEx without freezing growth.
Expand existing capacity
Before investing in new machines, it pays to see how well you’re using the ones you already have. With real-time dashboards, Leanworx shows exactly which machines are running, idle or stopped — no more assumptions about ‘full load.’
If two machines are consistently sitting idle during the night shift, the system highlights not just the idle hours but also the reasons logged by operators. That way, you can quickly plug the gaps in scheduling or manpower and unlock capacity that was slipping away.
Opt for smart maintenance
Maintenance is often either reactive (fix it when it breaks) or excessive (service it too often). Leanworx finds the sweet spot by auto-logging breakdowns, tracking Mean Time Between Failures (MTBF), and sending alerts when stoppages cross limits.
Say a CNC’s spindle downtime goes over the set threshold — the system instantly flags it. The maintenance team can then schedule checks at the right time, avoiding costly breakdowns without wasting hours on over-maintenance.
Turn OEE insights into extra output
How do you know if you’re getting the best out of your machines? Leanworx calculates OEE by tracking Availability, Performance, and Quality — not just at the machine level, but by shift and operator too. With drill-down reports, you can see whether losses come from downtime, slow cycles or rework.
This goes beyond rough estimates and often reveals hidden capacity of 20 to 30%. In one plant, the real culprit turned out to be slow cycle speeds rather than breakdowns — an insight that is difficult to obtain with manual logs.
Slash downtime
Lost hours are often discovered only at the end of the day, when it’s too late to do anything. Leanworx flips that by tracking downtime in real time, with operators logging reasons like setup, tool change or shift change.
The system also sends mobile alerts for prolonged stoppages. If a machine sits idle for more than 15 minutes, the supervisor’s phone buzzes immediately. That quick nudge allows action on the spot and, in many cases, saves the entire shift.
Build operator discipline
Performance data is powerful when it’s transparent. With Leanworx, operators have individual logins to record stoppage reasons, and supervisors get operator-wise performance reports. When everyone knows their numbers are visible and compared, excuses tend to fade, and accountability goes up. For instance, if an operator consistently shows lower utilization, the reports flag it right away. Instead of shooting in the dark, the plant head can see if the issue is training, material delays or discipline — and act accordingly.
A precision machining unit in Chennai saw this play out in real time. One operator’s utilization was consistently lower during the afternoon shift. At first, it looked like a focus problem. But the downtime logs told another story: repeated entries for “waiting for inspection clearance.”
The QC team was understaffed in that shift, creating a bottleneck. By simply adjusting inspection schedules and adding an inspector, the operator’s performance caught up with the rest — increasing shift output by 12%. Without operator-wise visibility, this would have been dismissed as a ‘discipline issue.’
