Quads
For India's machine shops

The tooling know-how behind India's biggest plants, now for every machine shop.

Quoting by the kilo and waiting on one senior programmer holds good shops back. Send a drawing and Quads returns the setups, the cutters, a rupee quote and a verified program, drawing on 30 years of Prosec tooling for Bharat Forge, Cummins, BHEL, Mahindra and Tata.

One part, end to end.

Twenty-four seconds, start to finish, on a real bracket. The file goes in, the setups get planned, the thin wall gets flagged, the job gets costed, the program gets written — and then the program gets checked back against the part.

Parts list · What comes out

One file in. Six things out.

Most tools stop at one of these. A quoting engine gives you a price and no program. A CAM package writes a program but needs someone to drive it. Quads takes the part from end to end, and every step is derived from the geometry rather than typed in.

ITEM 01The setup planHow many setups, what gets cut in each, and where the part has to be flipped — worked out from the features, not from a template.
ITEM 02Problems, before cuttingThin walls, deep pockets, awkward holes — flagged with the reason, while it's still cheap to change something.
ITEM 03The cutter listEvery operation resolved to a specific cutter, and every cutter resolved to a real part number you can order against.
ITEM 04The costMaterial, setup and machine time in rupees, built up from the plan rather than guessed at a rate per kilo.
ITEM 05The programG-code with the tool changes, depths and feeds, generated from the same plan that produced the quote.
ITEM 06The checkThe program is read back and compared against the part it came from, so the code and the model agree before anything runs.
Schedule C · The laws

The engineering laws, written down.

A good machinist carries these in their head: how thin a wall can go before the cutter pushes it away, how deep a hole before the chips jam, how hard a spindle can pull before it stalls. When that person is on leave, so is the knowledge.

Quads writes each one down as a law with a number on it, and runs every one against every part you send. You see all of them on the quote — the ones that passed as well as the ones that fired — with the limit each one used.

1 · THE SHAPE OF THE PART15 LAWS
Thin wall — a cutter pushes it away0.8 mm
Wall thin enough to need a lighter cut1.5 mm
Thin floor — nothing behind it to damp it0.8 mm
Pocket depth against its width4 : 1
Hole depth against diameter — chips stop clearing5 : 1
Internal corner radius against the smallest cutter0.5 mm
Hole tilted away from the spindle5°
Share of the part that is really lathe work35%

Plus seven that fire on sight: square internal corners, undercuts, islands, overhangs, flat-bottomed holes, faces no setup can reach, and work on faces nobody planned for.

2 · CUTTING PHYSICS3 LAWS
Spindle power — P = kc × MRR, against the motor's continuous rating≤ rating
Tool bending — the cutter as a cantilever, δ = F·L³ / 3EI0.05 mm
Spindle speed — rpm from surface speed, against the machine's top speed≤ max rpm

Worst case across every operation on the part — one cut over the line is one cut that stalls or misses size, so an average would hide it. Cutting energy kc is set per material.

3 · HOLDING THE PART2 LAWS
Block across the jaws, against what the vice opens to≤ opening
How far the block stands out of the jaws before it needs supportratio

Checked against the vice you picked, on every quote.

4 · THE PROGRAM, READ BACK6 LAWS
A complete program — loads a tool, moves, ends cleanlypass / fail
Offsets, feed, spindle and cycles active at every linepass / fail
Every speed one the machine can reachpass / fail
Every move inside the machine's travelpass / fail
Nothing cuts below the block, into the vice3 mm
No cutting feed spent in fresh air above the blockpass / fail

Every program is read back line by line against the block and the machine before you see it.

26 LAWS · EACH ONE A LINE IN THE ENGINE, WITH ITS LIMIT BESIDE IT The limits are sensible starting points, not certificates — a shop can tune them. And we show how far each rule has been checked against outside references, including the ones that haven’t been yet.
Detail D · Tooling

Thirty years of picking cutters, written into the engine.

Knowing a job needs a 10 mm flat end mill is the easy half. Knowing which one, in which grade, for Inconel at that depth of cut, is the part that takes a career.

Quads is built on Prosec, a cutting-tool business that has been solving exactly that problem for Indian manufacturers for three decades — including Bharat Forge, Cummins, BHEL, Mahindra and Tata. The engine specifies the cutter. Prosec supplies it, and regrinds it when it’s worn.

TitaniumInconelStainlessMonel
The materials where guessing the tooling is expensive.

Every cutter resolves to something you can order

Each operation is matched against the catalogues Prosec carries — checking the geometry agrees and that there’s a real part number behind it — so what comes back is a tool list you can buy, not a shopping brief.

Where a cutter isn’t something we carry, you still get the full specification — diameter, geometry, grade, reach — so you can order it anywhere. We’d rather tell you that than steer the plan towards what’s on our shelf.

Inspection · Verification

Generated code you can actually run.

The reasonable objection to automatic programming is that nobody wants to find out it was wrong when the tool is already in the material. So the program doesn’t just get written — it gets read back and checked against the part it came from.

Every step shows its working: which feature drove which operation, which operation called which cutter, and why the plan is in the order it’s in. If you disagree with a decision, you can see the one to change.

NOTES — WHAT WE DON’T CLAIM
1.
A geometric match to a catalogue is a matchNot a stock check, not a quotation, and not a promise from the manufacturer. Where a figure is measured we say so, and where a sample doesn’t represent a real order book we say that too.
2.
The engine flags what it can’t resolveRather than filling the gap with something plausible. On a shop floor, a confident wrong answer costs more than an honest gap.
Detail F · Regrinding

Maintaining original geometries and performance.

Prosec runs its own regrinding facility, so a cutter Quads specified doesn’t end its life in a scrap bin. It comes back, gets returned to its original geometry and recoated with a global premium coating partner, and goes out again. You keep running the same parameters you always did — with shorter processing times, you hold fewer tools in stock.

Why this matters beyond the cost

A tool that comes back tells us how the tool we chose actually performed — how it wore, how long it lasted, and whether the plan asked too much of it. That goes back into the engine, so the next part of the same kind gets a better answer.
