A monthly people review for CNC and precision machining shops: ten questions for the owner

Most owners of CNC shops can quote this month's billing to the nearest lakh, and each customer's overdue invoices besides. Ask how many spindle-hours were lost waiting for a setter and the reply is usually a guess. The first number gets a weekly look. The second gets noticed only when a buyer complains about a late lot.

A short review, held on a fixed day each month, closes that gap. The ten questions below are the template. Ask them in an unchanging sequence, so trends surface without anyone building a report.

1. Which lathes, VMCs, grinders or EDMs had under two signed-off names on any shift?
2. How many spindle-hours were lost waiting for a setter, a CAM programmer or a CMM slot, and why?
3. Who climbed a matrix level in the last four weeks, and who has sat on one level, on one machine, for over a year?
4. Whose overtime topped the register, and are they the same names as last month?
5. How did good parts, scrap and rework compare between the day crew and the night crew?
6. Which rejections came back from customers' goods-in, and who on the floor answered each one?
7. Are this month's joiners on their first-week sheets, and which probation reviews fall due?
8. Who resigned, and what did they tell the time office, the canteen or a mate at the next machine?
9. Has a key setter, grinder or programmer mentioned an outside offer, a pay grievance or a plan to leave?
10. Which near misses, swarf cuts, coolant rashes or interlock faults were reported, and what was done?

1. 1

   Fix the date and keep it

   Same week each month, ideally after wages are processed so overtime and attendance figures are final. Forty-five minutes is enough once the habit settles.

2. 2

   Prepare answers, do not discuss them

   The office manager collects answers from the skill matrix, handover sheets, the biometric export, the rejection log and the incident register two days before. The meeting itself is for decisions.

3. 3

   Owner, plant head and one voice from the floor

   Bring the senior setter or quality lead in for items one, two and six. They know why a figure reads as it does, and which CMM queue or tool crib shortage sits behind it.

4. 4

   One action per question, with a name

   If a question needs nothing this month, write that down. If it needs something, write who will do it and by when.

5. 5

   Start with last month

   Before item one, go through each action from the previous review. One carried three months running needs a different owner or a smaller first step.

Items one and two are about cover. A twin-spindle lathe or a fourth-axis VMC with a lone cleared person per shift is one resignation away from standing still. Idle hours, read off the production log or the machine's own spindle-hour meter, show where that is already costing you. Item three is about the ladder. An operator parked on the same bar-fed lathe for years, never trusted with an offset, starts taking calls from the next industrial estate.

Items four and five look at hours and shifts. Overtime that lands on the same three setters month after month is a fatigue risk and usually means thin cover. Night batches that scrap more bores than day batches point to staging and authority more often than attitude. Item six keeps quality ownership visible. If the owner personally answers every rejection tag and customer email, nobody at the spindle learns from one.

Items seven to nine follow people in and out. Joiners without a buddy drift to the wash tank and stay there. A missed probation date turns into a confirmation by default. Leavers often tell the security guard, the canteen cook or a friend on the next machine the real reason, so ask there. Item nine is the early warning: where good setters and grinders are known by name around the estate, offers arrive by phone long before any resignation letter. Item ten comes last but is never skipped. A near miss at a cylindrical grinder, or a VMC door interlock wedged with a rag, is the cheapest warning you will get.

• A sliding-head lathe whose only night operator has asked for leave over Diwali.
• Spindle-hour readings flat on a VMC that was bought to run a second shift.
• One grinder logging double shifts three weekends running.
• Rejection tags clustering on a single bore size, all from night batches.
• A helper still deburring at the wash tank a month after joining.
• A CMM queue that pushes first-off approval past lunch most days.
• A coolant splash or swarf cut dressed from the first-aid kit but missing from the register.

Resist adding questions. Ten is enough to cover the shop, and a longer list becomes a report nobody prepares on time. If one item keeps throwing up the same problem, move it out of the monthly hour and make it a project with its own owner and deadline.

• Skill matrix on the time office wall: items one and three.
• Machine handover sheets and the spindle-hour log: items two and five.
• Biometric attendance export and the overtime register: item four.
• Rejection tags, the red-bin count and customer emails: item six.
• Joining file, buddy sheets and probation dates: item seven.
• Exit notes, the gate register and the plant head's notebook: items eight and nine.
• Near-miss slips and the first-aid register: item ten.

If any of these sources is missing, building it is the first action. Our reporting set-up creates the handful of figures this review needs.
