Gas Metal Arc Welding (GMAW) / MIG Welding
A semi-automatic or automatic process that uses a continuously fed wire electrode and a shielding gas (like argon or CO₂).
🔹 Fast and easy to learn; ideal for production environments.

Gas Tungsten Arc Welding (GTAW) / TIG Welding
Uses a non-consumable tungsten electrode and an inert gas (usually argon) to shield the arc. Filler metal may be added manually.
🔹 High-quality welds; great for thin materials and precision work.

Flux-Cored Arc Welding (FCAW)
Similar to MIG welding, but uses a tubular wire filled with flux. It can be used with or without shielding gas.
🔹 Good for outdoor welding and thicker materials.

Shielded Metal Arc Welding (SMAW) / Stick Welding
A manual arc welding process that uses a consumable electrode coated in flux. The electric arc is struck between the electrode and the workpiece. The flux coating creates a gas shield and slag to protect the weld.
🔹 Common in construction and repair work.

1. Laser Cutting (Sheet Metal Cutting by Laser)
Laser cutting is a high-precision thermal cutting process that uses a focused laser beam to melt, burn, or vaporize material, typically sheet metal, along a programmed path.

🔹 Process Description:
A high-power laser beam (commonly CO₂, fiber, or Nd:YAG) is directed through a nozzle and focused on the material surface.

Assist gases (oxygen, nitrogen, or compressed air) are used to enhance cutting quality, eject molten material, and prevent oxidation.

The laser head follows a CNC-controlled path to achieve intricate shapes and complex geometries with minimal heat distortion.

🔹 Materials:
Carbon steel, stainless steel, aluminum, brass, copper, etc.

Common thickness range: 0.5 mm – 25 mm (depending on material and laser power)

🔹 Advantages:
High precision and edge quality (kerf typically <0.2 mm)

No need for additional finishing (burr-free in many cases)

Ability to cut complex contours with tight tolerances

Minimal material deformation due to small heat-affected zone (HAZ)

High repeatability and automation via CAD/CAM integration

2. CNC Press Brake Bending (Abkant Bending)
Press brake bending, often referred to as Abkant bending (from German), is a cold-forming process used to bend sheet metal using a hydraulic or electric press brake equipped with upper (punch) and lower (die) tools.

🔹 Process Description:
The sheet metal is positioned between a V-shaped die and a corresponding punch.

The CNC-controlled ram (upper beam) forces the punch into the die, plastically deforming the material along a straight axis.

Backgauges and CNC systems ensure precise part positioning and bending angles.

🔹 Bending Types:
Air bending (most common) – The punch doesn’t fully bottom into the die; allows for angle flexibility.

Bottom bending – The material is pressed fully into the die for greater accuracy.

Coining – High-pressure bending for very tight tolerances and minimal springback.

🔹 Capabilities:
Bending length: Depends on machine (commonly 1000 mm to 6000 mm or more)

Bending force: Depends on material thickness and type (measured in tons)

Bend angle accuracy: ±0.2° or better on CNC machines with angle measurement systems

🔹 Materials:
Mild steel, stainless steel, aluminum, brass, and other sheet metals

🔹 Advantages:
High precision and repeatability due to CNC control

Multiple bends can be programmed in a single setup

Reduced setup time with automatic tool changing systems (on high-end models)

Suitable for both prototyping and high-volume production

🔩 Combined Process Workflow:
Laser Cutting: Flat pattern is cut from sheet metal with precise profiles and cutouts.

CNC Bending: Cut parts are transferred to the press brake for bending operations based on design specifications.

Quality Check: Final parts are inspected for dimensional accuracy and angle precision.

🔧 1. General Milling Process Overview
Milling is a subtractive machining process that uses a rotating cutting tool with multiple cutting edges to remove material from a workpiece. The workpiece is typically fixed on a flat table and moved relative to the rotating cutter, or the cutter is moved across a fixed part.

🔹 2. Conventional (Manual) Milling Machines
Axis capability: Usually 3-axis (X, Y, Z) with manual control over table movement and spindle.

Work setup: The workpiece is clamped onto the machine table using vises, T-slot clamps, or custom fixtures.

Operations performed:

Face milling

Slotting and pocketing

Drilling and tapping

Contouring and profiling

Angular or inclined surfaces using tilting vises or rotary tables

Tooling: High-speed steel (HSS) or carbide end mills, face mills, and slot drills.

Precision and repeatability: Limited by operator skill, manual backlash, and machine wear. Suitable for simple geometries and one-off or low-volume production.

Typical applications: Maintenance, repair jobs, prototypes, and small batch parts.

🔹 3. CNC Milling – 3-Axis and 5-Axis Machines
CNC milling machines offer high-precision, automated control with programmable tool paths and consistent part quality, ideal for both small and large components.

⚙️ 3-Axis CNC Milling
Axes: Movement in X, Y, and Z directions.

Applications:

2D and 2.5D operations (slots, contours, pockets)

Prismatic parts

Advantages:

Reliable accuracy

Suitable for long or wide parts due to large table capacity (up to 6000×2200 mm)

Cost-effective for parts with planar surfaces and simple features

⚙️ 5-Axis CNC Milling
Axes: X, Y, Z linear + A and B (rotary axes)

Applications:

Complex 3D geometries and freeform surfaces

Simultaneous machining of multiple sides of a part

Reduced need for repositioning or fixtures

Advantages:

Higher surface finish and dimensional accuracy on complex shapes

Increased flexibility for aerospace, mold & die, and high-precision industries

Enhanced tool access, allowing for undercuts and deep pockets

🏗️ Workholding and Table Capacity
Machines with worktables from 600 mm up to 6000 mm in length and up to 2200 mm in width allow the machining of both small precision components and very large parts (e.g., base plates, machine beds, structural components). Workholding systems include:

Modular clamping systems

Vacuum tables (for thin parts)

Magnetic chucks (for steel plates)

Custom fixtures for oversized components

📏 Precision & Tolerance Control
CNC machines typically hold tolerances within ±0.01 mm to ±0.05 mm, depending on tool condition, setup rigidity, and machine calibration.

High-end 5-axis machines equipped with thermal compensation and in-process measurement probes can maintain tight tolerances even on large workpieces.
