(16 cards)
What is Metal Forming?
Metal forming is a manufacturing process where the shape of a metal workpiece is changed using plastic deformation, without removing any material.
Metal forming adalah proses manufaktur untuk mengubah bentuk logam melalui deformasi plastis, tanpa mengurangi volume material.
Rolling
Metal is passed through rollers to reduce thickness
Logam dilewatkan antara rol untuk menipiskan
Forging
Shaping metal using compressive force (hammer/ press)
Membentuk logam dengan tekanan tinggi
Extrusion
Forcing metal through a die to get specific shape
Menekan logam lewat cetakan
Drawing
Pulling metal to reduce diameter (e.g. wire drawing)
Menarik logam untuk mengecilkan diameter
What Is Sheet Metalworking?
It deals with cutting and forming thin metal sheets (less than 6mm).
Ini adalah proses pemotongan dan pembentukan lembaran logam tipis (kurang dari 6mm).
Shearing
tool : Shear blade
purpose : Cut metal sheet
Bending
tool : Press brake
purpose : Create angular bends
Punching
tool : Punch + Die
purpose : Create holes
Blanking
tool : Die
purpose : Cut out parts (remains = scrap)
Deep Drawing
tool : Die + Punch
purpose : Make cup-like shapes (e.g. cans)
Press Brake
function: Bending sheets accurately
Hydraulic Press
function : Used in deep drawing, forging
Laser Cutter
High-precision cutting
Die & Punch
Core tools for shaping sheet metal
In an international company, especially in manufacturing:
• CAD/CAM is used to design and simulate forming processes
• Machines are CNC-controlled (automation is big!)
• Quality control uses digital calipers, 3D scanners, CMM
• Materials commonly used: Aluminum, Mild Steel, Stainless Steel
