Two People per Machine on the Payroll, One at the Machine: How Many Does Your Shop Really Need?

Two People per Machine on the Payroll, One at the Machine: How Many Does Your Shop Really Need?

By The Mama Editorial Team · Factory-floor cameras, India compliance & operations

Your payroll shows about two people per machine but you only ever see one at it, so how many does the shop really need? As of 17 Oct 2026 there is no published Indian norm. Build the crew role by role instead. On an assumed 40-machine Haryana shop, 1.8 heads per machine per shift against a designed 1.3 costs about ₹3.5 lakh a month for each shift.

By the Mama Editorial Team, for promoters and MDs of machine shops and auto-component units with 30 to 100 machines. Last checked: 17 Oct 2026. Every ₹ figure below either comes from a named primary source or is marked as an assumption. This page is about crew design. It is not a case for cutting people.

Key takeaways

Count minutes of work, not machines

"Two per machine" is usually a habit from the days when every lathe was manual and every operator had a helper beside him. A bar-fed turning centre or a long-cycle VMC needs a person at load, unload and first-off check, and little in between. A conventional lathe still needs one person for the whole cycle.

So ask how many minutes of human work each machine needs per hour. At 15 minutes, one operator can tend two or three machines. At 60 minutes, the machine needs its own operator, and a second person beside him is waiting.

No published Indian standard sets crew ratios by machine type (search of dcmsme.gov.in project profiles and general web search, 17 Oct 2026). The ratios below are assumptions to replace with your own timings.

The roles that sit behind one machine

Walk your machine shop with the muster in hand and sort every name into one of these roles.

  1. Operator. Loads, unloads, measures, starts the cycle: the person you see at the machine.
  2. Helper attached to an operator. Fetches material, clears chips, carries parts. Often needed only on heavy parts or very short cycles.
  3. Loader and material mover. Brings stock to machines and bins to washing and dispatch. One person serves many machines.
  4. Deburring, washing and packing hands. Off-machine work the machining creates.
  5. Setter. Changes jobs and proves the first piece; often the bottleneck.
  6. Inspector. First-off, in-process and final checks.
  7. Relief cover. Heads carried so the shift runs when people are absent.
  8. The contractor's man. Any of the above, billed through a manpower contractor.

Each role is legitimate; trouble starts when nobody knows how many of each the shop was designed for.

Building the crew for a 40-machine shop

Here is a designed crew for one shift on an assumed 40-machine shop. The machine mix, the tending ratios and the shared roles are all assumptions. Swap in your own.

Role / machine group (assumed) Machines Assumed ratio Heads per shift
CNC turning with bar feeder 8 1 operator per 2 machines 4
CNC turning, manual load, short cycles 8 1 operator per machine 8
VMC, long cycles 10 1 operator per 2 machines 5
Conventional lathes 8 1 operator per machine 8
Drilling and tapping 6 1 operator per machine 6
Operators subtotal 40 31
Setters — 1 per 10 machines 4
Inspectors (first-off and in-process) — assumed 3
Loaders and material movers — 1 per 10 machines 4
Deburring, washing, packing — assumed 4
Relief cover for absence — about 8.5% of the 46 above 4
Shift-in-charge and tool crib — assumed 2
Designed crew 52 (1.3 per machine)

The relief line should come from your own absence rate. The Labour Bureau's Indian Labour Statistics 2022-23 puts absenteeism among directly employed regular factory workers in 2021-22 at 8.40% in Haryana, 8.71% in Maharashtra and 6.87% all-India (Table 6.1(b), Labour Bureau). Use your own rate if you have it.

Now take the same 40 machines carried at 1.8 heads per machine, which is 72 people per shift. In a shop like that, the extra 20 typically sit like this (assumption):

Where the extra heads sit (assumed) Heads per shift What they mostly do
A helper beside an operator on machines that do not need one 12 Wait out the cycle, then carry parts
Extra loaders and movers 4 Peak when a heat or a forging lot arrives, idle in between
"General" contract heads with no fixed role 4 Whatever the supervisor needs that hour
Extra over the designed crew 20

None of these 20 is idle by choice: the plan never gave them the next job.

What the gap costs at minimum-wage level

The extra heads are mostly unskilled, so we price them at the unskilled rate.

Haryana. Assume ₹590 a day for an unskilled worker (₹15,340 a month over 26 days), ₹650 for semi-skilled and ₹710 for skilled (all illustrative). Take the current notification for your trade from your state labour department (Haryana Labour Department).

Maharashtra. Assume ₹535 a day for an unskilled Zone I factory worker (₹13,910 a month; illustrative). Take the current schedule for your trade and zone from the Maharashtra Labour Commissionerate. Each state notifies its own minimum wages by trade and skill level, and most revise the DA part twice a year.

On-costs: employer ESI is 3.25% of wages under rule 19 of the Social Security (Central) Rules, 2026 (G.S.R. 344(E), 8 May 2026). Employer PF under section 16 of the Code on Social Security, 2020 is 10% of wages, or 12% for establishments the Centre notifies (e-Gazette). For the example, assume the 12% rate, all workers within ESI coverage, and PF paid on the full wage.

Cost of 20 extra unskilled heads Haryana, assumed wage (₹) Maharashtra Zone I, assumed wage (₹)
Monthly wage per head 15,340 (assumption) 13,910 (assumption)
Employer ESI 3.25% (rounded up) 499 453
Employer PF 12% (assumed rate) 1,841 1,669
Cost per head per month 17,680 16,032
20 heads, one shift, per month 3,53,600 3,20,640
20 heads, two shifts, per month 7,07,200 6,41,280
Two shifts, per year 84.9 lakh 77.0 lakh

If the 20 come through a contractor, add his service charge on top. Assume 8–10%: that is your contract, not a statutory figure. The contract labour cost calculator does this sum with your own rates.

These are minimum-wage floors; real pay is usually higher.

The contractor's men: what the Code text says

Many shops carry the second person per machine through a contractor. Four provisions of the Occupational Safety, Health and Working Conditions Code, 2020 (e-Gazette text) are worth reading before you design a crew that way.

Read together, the text treats a contract operator on a CNC differently from a contract loader at the dock. Whether a given role is core is for your labour counsel and, under section 57(2), the appropriate Government. The contract labour headcount article covers the separate problem of billed heads who never reach the line.

Redesigning the crew without a layoff

A ratio of 1.8 against a design of 1.3 is not a list of 20 people to let go. It is people-capacity the plan is not using. Four ways to put it back to work:

  1. Staff the shift you could not staff. Twenty surplus heads are nearly 40% of the 52-person designed crew for a whole extra shift.
  2. Train helpers into operators. On the assumed rates, the unskilled to semi-skilled gap is ₹60 a day (₹1,560 a month), small for an operator who can tend two machines.
  3. Pool the helpers. Move them off single machines into a material-and-deburr team with a clear route.
  4. Let attrition do the rest. Freeze replacement hiring for roles over design.

First check whether the setter is the bottleneck: if changeovers queue, operators and helpers wait together, and a second setter can be cheaper than the waiting crew. The setter dependency article works through that case.

What cameras can and cannot tell you here

They can count heads per zone per hour. A camera over a bay shows how many people stood at the turning cells between 10:00 and 11:00, and how many machines were cutting. Next to the muster and the designed crew, the gap becomes a visible pattern.

They cannot tell you who is a helper and who is an operator. A count is a count. Role comes from your muster and your crew design, not from the image.

They cannot judge whether a helper was needed. Forty minutes beside a machine might be waiting, or holding a casting too heavy for one person. That call belongs to the supervisor.

They should not track individuals. Crew design needs aggregates per zone and hour; identifying people moves the talk from planning to blame. Footage of recognisable workers is personal data under s.2(t) of the DPDP Act, 2023; tell workers in writing what is recorded and why (see the worker CCTV notice under DPDP).

They miss uncovered rooms. Tool crib, washing bay and inspection room are often off-camera.

Where Mama fits

Mama reads the cameras a shop already has and sends the owner a short morning note on yesterday's machine hours: which machines cut, which waited, and how many people were in each zone while they waited. Counts stay at zone and shift level, with no names and no operator ranking. If you want Mama to look at your floor, leave an email or phone in the form below.

FAQ

How many workers per machine is normal in an Indian machine shop? There is no published Indian norm. No government or industry-body standard for machine-shop crew ratios was found (checked 17 Oct 2026). The ratio depends on machine type, cycle length and how much off-machine work you do. Build the crew role by role, as in the 40-machine table above, and compare your muster with that.

Can one operator run two CNC machines? Often, when the cycle is longer than the load, unload and inspection time on the second machine. Bar-fed turning and long-cycle VMC work are the usual candidates; short-cycle manual-load jobs are not.

Do minimum wages apply to helpers supplied by a contractor? Section 55(3) of the OSH Code, 2020 makes the principal employer liable for wages a contractor fails to pay or short-pays, with a right to recover them from the contractor. The wage floor for the trade comes from your state's current minimum-wage notification.

Is a ratio of 1.8 people per machine always too high? No. Heavy castings, heavy deburring, in-house inspection and high absence can justify more. The point is to know which roles make up the 1.8 and check each against the work it does.

What should I do with surplus helpers? Treat them as capacity: staff an extra shift, train them as operators, pool them, and freeze replacement hiring.
