Many decisions sit between a drawing and the finished part: which order of operations makes sense? How is a complex geometry developed into a flat pattern? Where can welding cause distortion? And how can a solution developed once be repeated reliably later?
At stainlesstec, programming and production planning connect the customer’s design with what actually happens in the shop.
CAD data · production planning · programming · work sequences · variants · small batches
The drawing describes the goal. We plan the route to it.
A technical drawing or 3D model defines what a part should look like in the end. What it does not answer is:
how the part is most economically cut
which bending sequence is technically possible
which surfaces have to be worked first
how individual parts are prepared for a welded assembly
how the workpiece is clamped
what work is still possible after welding
when straightening or surface finishing makes sense
Those are exactly the questions production planning answers. It translates design into manufacturing.
CAD data become machine programs
We work from data: yours form the basis for cutting, machining and later repeat production. Depending on the part, they become programs for laser cutting, laser punching, CNC bending, 3D laser welding and other CNC operations.
This is not a matter of transferring a contour to a machine. A program has to suit the geometry, the machine, the tooling available, the thickness, the grade and the operations that follow. Good programming therefore means more than “import the file and press start”.
Reviewing manufacturability
A part can look perfect in the CAD model and still be difficult or needlessly expensive to make. Typical questions:
Is the intended bend radius achievable?
Will there still be enough tool access after several bends?
Can a weld still be reached later?
Can the tolerances be held across several operations?
Is the intended thickness sensible for the geometry?
Does the design create needless welding or assembly work?
We identify points like these before production starts wherever possible and agree any improvements with you. Responsibility for the design remains with the client or the responsible engineer. More under Capability & limits.
The order of operations decides the result
On complex parts, it matters not only what is made but in what order:
Bend too early and a later surface can no longer be worked.
Weld a part up completely too early and nobody can reach the inside to grind it.
Lay a critical weld in the wrong order and the whole assembly distorts.
We therefore plan the route backwards from the finished part: every operation has to make the next one possible.
Flat patterns for complex geometries
With hoppers, cones and round-to-rectangular transitions, enclosures, folded special parts and multi-part welded assemblies, a three-dimensional design first has to become a sheet metal geometry that can be made. Blanks, bend lines, segmentation and weld edges are all defined in the process.
The challenge is to divide the design so that it stays manufacturable, dimensionally accurate, weldable and economical. A considerable part of the technical value is added here, at the screen.
Thinking the bending sequence through
CNC bending shows well how closely programming and experience work together. A complex sheet metal geometry can contain numerous bends, and each one affects:
the next tool position
accessibility
how the workpiece is supported
possible collisions
the eventual geometry
Our planners therefore develop not just angles and programs but the whole bending strategy.
Welded assemblies begin in production planning
High-grade welding, too, is prepared long before any welding:
sensible division of the part
access to the seams
weld edges
the need for fixtures
tacking sequence
welding sequence
critical tolerances
subsequent work
On demanding assemblies, programming, production planning and our specialist welders therefore work closely together. The best weld is of little help if the manufacturing strategy is wrong.
Fixtures and clamping
Not every design can sensibly be made freehand. On welded assemblies, small batches, thin-walled structures and complex geometries, fixtures or special clamping arrangements make sense. They help to:
position parts repeatably
hold tolerances
control distortion
cut processing times
repeat follow-on orders reliably
Whether a fixture pays off depends on the part, the quantity and how likely a repeat is.
A one-off needs different thinking from a series
Production planning has to suit the lot size. On a one-off special part, elaborate automation would not pay; on a recurring small batch, extra preparation pays off quickly:
one-off – focus on a flexible, economical route
prototype – try the process out and learn from it
pre-production – stabilise the routine and check repeatability
small batch – use programs, fixtures and work sequences repeatably
Many customers build machines or plant in several versions, which produces parts that resemble one another but differ in dimensions, hole patterns, connection positions, thicknesses, surfaces or built-in components.
Clean data and production planning keep such variants properly apart. That lowers the risk of an old drawing, a wrong revision or the wrong version reaching the shop floor.
Changes have to stay traceable
On recurring small batches in particular, a design changes over time. What then matters is: which revision applies? Which programs belong to it? Which operations were changed?
A controlled data base is therefore part of modern manufacturing. Repeatability means not only that the machine does the same thing, but that it is unambiguous which version is to be built.
Programming and the shop floor belong together
Production planning must not be an isolated office process. The best insights come from talking to the shop floor: an operator spots a better way to clamp the part, a welder a better seam order, someone in surface finishing sees that an area will no longer be reachable later.
That knowledge flows back into the process: data provide the basis, experience improves the process.
When a part comes round a second time
One of the great strengths of structured production planning shows on repeat orders: programs, work sequences and the experience from the first order can all be used again. That makes it possible to:
cut set-up times
stabilise routines
keep variants cleanly apart
reproduce quality
avoid sources of error
That makes us particularly interesting for customer-specific small batches and recurring special parts.
Working with the customer
On demanding parts, technical discussion is worthwhile. Typical topics:
manufacturability
material thicknesses
bend radii
tool access when bending
seam positions
surfaces
tolerances
assembly sequence
Our aim is not to take over your design. We bring the shop floor’s perspective: you know the function. We know the process.
Develop the manufacturing strategy – process, sequence, fixturing
Create the programs – laser, punching, bending, other CNC processes
Support production – feedback from the shop floor and from welding
Keep the data – for repeat parts, variants and small batches
What we need from you
3D data, preferably STEP
DXF data for sheet metal parts, where available
technical drawings
unambiguous revision status
material and thickness
quantity
critical tolerances
surface requirements
welding requirements
test requirements
parts lists for assemblies
On complex assemblies, complete CAD data are particularly helpful.
The machine runs the program. We develop the process behind it.
From the first review of the CAD data to a repeatable small batch, our programmers and planners bring design, machines and shop-floor experience together.
A drawing thus yields not just a part but a process under control.
