A quotation is going out to a buyer in Germany. The price is right. The lead time is right. The drawing is signed off. Then one line comes back: what is the carbon figure for this part, per unit, and can you show your working.
Nobody on the quoting side has that number. Nobody in the design office has it either. The part was drawn to carry a load and fit an envelope. It was never drawn to answer a question nobody used to ask.
Someone puts a figure together anyway, from the material grade and a guess at the machining time. Saying something soft felt better than saying nothing. The buyer notices the softness. The quote sits a week longer than it should have, for a question that had nothing to do with whether the part is any good.
Why we build it this way
The easy fix is to hire this out: bring in a consultant once a year, run a carbon report across the whole plant, hand over a number whenever someone asks. We think that answers the wrong question. A buyer asking for a carbon figure at quotation time is not asking about the plant. They are asking about this part, in this material, made this way. Change the material or the process and the true number changes with it, the same way the cost in rupees does.
An annual report cannot do that. It is a plant-wide average, worked out long after the part shipped, from spend data rather than from the part itself. It cannot be defended line by line when a buyer pushes on it. And it cannot tell a design engineer anything while she still has the drawing open and the chance to change it.
A carbon figure that cannot move when the design moves is not a design tool. It is a report someone wrote afterward and hoped nobody would question.
So the number has to come from the part itself, while the part is still a drawing and not yet a purchase order. That is the same moment the load path already gets checked, because both questions are really asking the same thing: what did this shape actually cost to make.
How it works, roughly
VCAD reads what the part is made of and how it will be made:
- The material and its grade.
- The process — casting, machining, sheet metal, whatever the drawing calls for.
- The geometry itself, since a thicker rib or a bigger casting is more material either way.
Alongside the usual read on where the load travels through the part, it gives back a carbon figure broken down by material and by process, attached to that specific part rather than to the plant as a whole. Change the design and the number moves with it, the same way the load path does.
If the figure looks wrong for what is actually being built, or an engineer would answer a competitor's question differently, that is the moment to look again at the material and process behind it and correct it — before it goes into a quotation, not after one comes back questioned.
A year of this is a quoting team that can answer the carbon question the same day it is asked, with a number that traces back to a real part instead of a plant average. What ships is still an engineer's decision, and the record behind that number stays on a machine in your own building.
VCAD is the third of three engineering aids under VarahiEdge. VEDA reasons about a fault from the machine's own signals, and Nirdesh guides a technician through a procedure by voice. All three run on the same on-premise box, inside the building where the machines actually are.
