Turning (Turning Operation)
Lathe is a metal cutting by allowing the workpiece (work piece) to rotate around itself. with the turning knife moving towards the workpiece There are two main types of turning.
Face turning is metal cutting by having the knife cut the workpiece across the workpiece.
Stripping is cutting metal by having the cutting knife move along the workpiece parallel to the axis of the workpiece.
The important factors that cause the process of stripping are
- Feed Rate
- Cutting Speed
- Depth of Cut
- Cutting Tool
- Workpiece to be machined
and when There is a turning process. The consequence is that
- Workpiece Dimension
- Surface Roughness
- Chip
- Wear of a turning knife (Tool Wear)
Casting
Casting is a type of metal forming. Which is suitable for the production of workpieces that cannot be formed by means of stamping, Welding, Machining, or forming by other methods and have a high production cost.
There are many factors to consider when choosing a metal casting method, such as
- The size or thickness of the workpiece,
- The shape and redundancy of the workpiece,
- Price
- Quantity to be produced
- Surface smoothness and type of metal.
- Processes related to metal casting processes such as Heat Treatment, Surface Treatment, Welding & Joining, etc.
