For over 85 years, Roller Die + Forming has been providing custom roll formed, stamped, powder coated and assembled metal parts, using lean manufacturing processes.
Roll forming, also known as contour roll forming, is a continuous process that forms metal sheet or coil stock into desired shapes by passing it through a series of roller dies. The stock is progressively worked through two or more stations until the finished shape is produced. Auxiliary operations like notching, slotting, punching, and embossing can be combined with roll forming. Contour roll forming is used across many industries like automotive, building, furniture, appliances, medical equipment, railcars, aircraft, and HVAC to produce a variety of metal products. It requires less force than other forming methods and allows theoretically unlimited length, while still strengthening the metal through controlled plastic deformation.
Steel is the basic material used for every kind of industry, particularly, the engineering industry, Iron ores are melted in a blast furnace, along with limestone and coke and after removal of impurities like sulphur and phosphorous, the molten iron is brought to its basic forms such as Mild Steel ingots, billets and slabs. These are used as raw materials for manufacturing different forms of steel to be used for specific purpose. These end products may be steel structures such as angles, channels or joists of various thicknesses and dimensions or plain rounds or twisted rods of varying diameters. Steel Re-rolling Mills convert billets and ingots to the required structures and sheets.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

4. What is ROLL FORMING?
Roll forming is a
continuous forming
process taking sheet
or coil stock and
bending or forming it
to a desired cross
section.
The process is
performed between
successive pairs of
rolls that
increasingly shape
the metal until the
desired cross
section is achieved.
7. Materials
Almost any material that can tolerate
bending to a desired radius can be roll
formed.
The more ductile a material is, the
better it will roll form.
The roll forming process can handle
ferrous, nonferrous, hot rolled, cold
rolled, polished, plated, or pre-painted
metals producing excellent results.
8. Materials
Materials as thin as 0.005" and as
thick as 0.750" can be roll formed,
depending upon the size of the roll
form machine spindles.
Material pieces as narrow as 1/8" and
as wide as 72", or more, can be roll
formed, depending on machine size.
9. Design Considerations
Bend Radii:
Best practice is a one-metal-
thickness inside radius.
May need slightly larger in high-
strength steels
Sharper corners CAN be obtained at
the expense of tool life
Scoring the inside of the strip can
help make sharper corners in some
cases.
10. Design Considerations
Deep sections:
Require more passes, larger
machines, larger rolls and dies
Risk overstressing the edges of the
material
Typical machines – 100 mm max.
height of part
Short Legs:
Three times metal thickness is a
good minimum leg length
11. Design Considerations
Wide sections
Apply ribs or offsets to wide panels
Helps prevent wrinkles, “oil-
canning”
Often wide material has appearance
issues
12. Design Considerations
Cross Section Tolerances
Typically +/- .25 mm to +/- .75 mm
Tighter tolerances are achievable:
Different approach to tooling
Special quality materials
Angular Tolerances
Typically +/- 1º
13. Design Considerations
Length Tolerance
Influenced by many factors:
Length of part
Speed of rollformer
Measuring system
Cutoff system
Material properties
Commonly available: +/- 0.8 mm
Special equipment and tooling: +/-
0.25 mm
Long parts (3 M or more): +/- 3.0 mm
and up
14. Design Considerations
Straightness:
Bow (up or down) or Curve (side to side) –
1.0 mm per Meter
Twist - 1 degree per Meter
Flare:
Typically avoid measuring the cross
section within 50 mm of ends.
Flare can be controlled with special
attention
17. Roll Forming vs. Other Processes
Volume is key versus tooling costs
Typically see 25,000 LF of part to justify cost
of custom shape; BUT, if can use standard
shape, much less
Extrusions – aluminum – 3 x galvanized cost;
inexpensive tools, expensive part
Press brake – good for low volume;
inexpensive tools, expensive part (labor), limit
to length of part by brake bed
Stamping – good for single part; if multiple
lengths in family, tooling very expensive; if
done in multiple steps, expensive (labor)
Roll form lines allow piercing, features to be
done in-line, no secondary operation.
