Training and competence: who is allowed to set a press or a brake

The competence matrix posted beside a 300 T press lists four authorised setters. At 06:15 the press is being set by a fifth person, a helper who has watched the job for two weeks and knows where everything is. The die goes in, the shut height is set by eye against the previous tool, and the first stroke closes the die on a 1.2 mm blank that was never meant to be there. Nothing is made that day, and the press tool goes to the tool room.

Press setter competence is the documented answer to a single question: which named person may change the tool and the settings on this machine class, for this tool type, and release the first part. The matrix on the wall is the visible part of it. The evidence behind it is an assessment record, a machine-class authorisation and an expiry date.

The plant, quality and sustainability hub covers the surrounding systems, including calibration, incoming inspection and shift handover.

Who is allowed to set a press or a brake?

Only a person whose authorisation record names that machine class and that tool type, and whose assessment is current. A job title is not an authorisation, and neither is length of service.

The reason is physical. Setting a 300 T press with a progressive die and setting a 20 T press with a single-stage tool use the same vocabulary and completely different risks. On the small press, a shut-height error of 0.5 mm may leave a burr. On the large press with a progressive tool, the same error can close the die on the material, spike the load beyond the press rating and break a punch before the first good part is made.

The arithmetic is not complicated. Die clearance on 1.2 mm CRCA runs about 0.08 to 0.10 mm per side, which is 6 to 8% of thickness. Setting the shut height 0.5 mm low closes that clearance and puts roughly 0.4 mm of interference into the tool. The press does not stop because it cannot; it delivers the load, and something in the die yields first.

The same logic applies at the brake, with different numbers. A 200 T five-axis brake with a 4,450 mm bed and a Delem control is a programming and angle-control competence: bend sequence, tooling station, crowning, springback allowance and the revision of the program that is actually running. Authorising a good press setter to run that brake unsupervised is a guess about a different skill.

What the authorisation has to name

A usable authorisation is more specific than a training certificate, and it answers four questions in one line.

The last row is the one that buyers underestimate. If the setter both makes the adjustment and signs the first-off, the verification step has been removed and the record proves only that someone was confident.

What an assessment has to contain to mean anything

An assessment is a demonstration on the machine, with the production tool, in front of an assessor who did not do the training. Four parts, and all four are recorded.

The practical. Set the tool from cold: load it, set the shut height, set the feed or blank position, check the die protection, run three parts and measure the two or three characteristics that decide fit. Then strip the tool and put it away correctly, because the strip-down is where damaged punches are found and where most setters are least careful.

The reasoning. Ask why the shut height is what it is, what happens if the material arrives 0.05 mm thicker, and what the setter would do if the first part measured 0.1 mm outside tolerance on a flange. A setter who can only repeat a sequence cannot handle the batch variation that arrives on a Monday.

The safety. Guarding and interlocks in place before the first stroke, lock-off procedure for the tool change, and what to do if the light curtain is muted or a two-hand control is bypassed. This is not a box to tick; it is the part of the assessment that prevents a hand injury.

The record. Name, employee number, machine class, tool type, date, assessor, result, restrictions and next assessment date, signed by the assessor and countersigned by the production head.

A written test of twenty questions is useful for the vocabulary, tonnage, clearance, shut height, die protection, and what to do with a suspect part. It is not a substitute for the practical, and a shop that assesses only in writing has documented the wrong thing.

The safety and legal frame

Indian law does not license press setters. What it does is place duties on the occupier of a factory, and those duties shape how the authorisation is written.

The Factories Act 1948 requires machinery to be fenced (section 21), sets conditions for work on or near machinery in motion (section 22) and requires that a young person is fully instructed as to the dangers, receives sufficient training and is under adequate supervision before working a dangerous machine (section 23). Section 23 is the closest the Act comes to a competence requirement, and it is a requirement about instruction and supervision rather than a certificate.

ISO 9001:2015 clause 7.2 then supplies the management system side: determine the competence necessary, ensure persons are competent, and retain documented evidence. ISO 45001:2018 clause 7.2 repeats it for health and safety, and clause 8.1.2 requires hazards to be eliminated where possible and risks reduced where they cannot be. On a press, the hierarchy runs guarding and interlocks first, then procedures, then competence, because a competent setter working without a guard is still exposed.

The practical consequence for a buyer is that the authorisation list is the record to ask for, not a certificate. There is no certificate to ask for.

What a brake setter has to hold in their head

The brake looks like the simpler machine and is the harder one to authorise, because the errors are small, systematic and invisible on the part until it is assembled.

Three numbers decide most brake work. The first is the bend allowance from the K-factor, which converts the flat pattern to the formed part. The second is springback. The third is the tolerance on the flange, which is where the first two arrive together.

Springback on a 90° air bend is roughly 1° to 2° for mild steel, 2° to 4° for stainless and about 2° to 3° for 5052 aluminium. A 2° error on a 40 mm flange moves the tip by 1.4 mm, which is nearly three times a ±0.5 mm general tolerance. That is why the brake program carries an angle correction and why an edit to that correction is a competence event, not a convenience.

A setter also has to know what the machine can physically do. A 200 T brake with a 4,450 mm bed forming 10 mm steel is nowhere near its limit in tonnage per metre, but the same brake with a narrow lower die and a short flange will exceed the tooling load long before the machine load. The bend allowance calculation covers the flat pattern; the authorisation covers who is allowed to change the correction that makes it match the press.

What goes wrong when an unauthorised person sets the machine

The failures cluster into four types, and each maps to a field on the authorisation.

Die damage from a shut-height error. A punch breaks, the tool goes to the tool room, and the parts made between the break and the detection are scrap with a missing feature. On a progressive die running at 60 strokes a minute, ninety seconds to detect a broken punch is 90 parts without the hole. The authorisation field is the machine class and the tool type.

Burr and die wear from a wrong shim stack. A shim left out raises the punch relative to the die, the clearance opens, and the burr height grows from 0.05 mm to 0.2 mm over a run. The part passes a dimensional check and fails at the weld or at the customer's edge inspection. The authorisation field is the setup scope, which separates a minor shim change from a full set.

Tool damage at the brake from the wrong station. A punch and die pair used outside their rated thickness range takes the load on the punch tip rather than the shoulders. The tool is damaged and the angle is wrong before the tool fails. The authorisation field is the tool type, not the machine.

A first-off released by the person who adjusted the machine. No failure is visible on the day. The verification step has gone, and the next lot inherits whatever the adjustment did. The authorisation field is the first-off authority, which is why it sits on a different name.

The requalification triggers that matter

An annual observation is the baseline. Four events should trigger a full re-assessment regardless of the calendar, and a shop that does not name them is running on a date rather than on evidence.

1. Twelve months away from that machine class, including a long absence or a transfer.
2. A die crash, a tool breakage or a press overload on that machine, because the cause is often a setting decision.
3. An injury or a near miss during a tool change or a setup.
4. A new tool type or a new machine class, for example a setter moving from single-stage work to a progressive die, or from a three-axis brake to a five-axis machine with a different control.

The record needs an expiry date for a dull reason: an authorisation with no end date is treated as permanent by everyone who reads it, including the person holding it.

What Ganesh runs

Ganesh has manufactured since 1992 and runs five units across Mumbai (Vasai) and Nagpur with more than 200 people. The machine range is the reason competence is authorised by class rather than by department: mechanical presses from 20 T to 300 T, a 250 T punching line, a 12 kW fibre laser with a 40 ft x 16 ft bed, a 200 T five-axis brake with a 4,450 mm bed forming to 10 mm, three CLOOS robotic MIG cells and more than 30 manual MIG/MAG, spot and SPM stations.

Press tools, progressive dies, welding fixtures and checking fixtures are designed and built in the in-house tool room, which puts the tool and the setter in the same organisation. When a punch breaks, the tool room sees the failure at first hand, and that feedback is what makes a setting standard worth writing down. The stamping capability describes the press range and the tool room.

The works hold ISO 9001:2015 and ISO 14001:2015 certification, and first article inspection and PPAP are available where a programme requires them. Both depend on the authorisation record: a first article produced by an unauthorised setter is a record of a process nobody agreed to.

What to put on the drawing and in the purchase order

Most of this belongs in the supplier's system rather than on the drawing, but four items belong in the enquiry or the purchase order because they change what the supplier has to demonstrate.

• The characteristics that decide fit, so the first-off check measures the right two or three features.
• Any requirement for a named setter or a dedicated cell, which is a capacity decision as much as a quality one.
• The record you want with the first lot: authorisation list extract, first-off results, and the assessment dates for the setters who ran the job.
• The notification rule when the setter or the tool changes on a repeat part, because a new setter on a running part is a process change even when the drawing has not moved.

The first article guide sets out what the record pack should contain; the authorisation list is the part most buyers forget to ask for.

When a formal authorisation is the wrong instrument

For a one-off prototype formed on a brake by the person who programmed it, a competence matrix is bureaucracy. The control that matters is the drawing review and the first-off, and the same person doing both is acceptable when the part is a sample.

It is also not a substitute for tooling condition. A fully authorised setter running a die with a worn punch guide will produce a burr that no authorisation prevents; the progressive die maintenance routine is the control for that.

And Ganesh does not certify other companies' setters or run an external training school. What we can show is the authorisation and assessment record for the people who set the machines running a customer's part, retrieved by machine class and name.

Send the drawing, the material and the annual quantity, and the engineering team will return the machine class, the tooling position and the first-off characteristics for the route. A quotation request with the part family and volume is enough to begin.
