pystyjyrsintä

Pystyjyrsintä, or vertical milling, is a machining process that uses a rotating cutting tool to remove material from a workpiece. The cutting tool is held in a spindle and rotates on a vertical axis. The workpiece is typically held on a table that can be moved in the X, Y, and Z directions, allowing for precise control over the cutting path.

The primary tool used in pystyjyrsintä is the end mill. End mills have cutting edges on their circumference and at their tip, enabling them to cut in multiple directions. Different types of end mills exist, such as flat-end mills for creating slots and shoulders, ball-end mills for creating curved surfaces and fillets, and chamfer mills for creating angled edges.

Pystyjyrsintä is a versatile process used in a wide range of industries, including aerospace, automotive, and mold making. It is suitable for creating complex shapes, precise features, and high-quality surface finishes. The process can be performed manually on manual milling machines or automatically on computer numerical control (CNC) milling machines. CNC machines offer greater precision, repeatability, and the ability to produce intricate geometries with minimal operator intervention.

Key parameters in pystyjyrsintä include spindle speed, feed rate, and depth of cut. These parameters are determined by the material being machined, the cutting tool used, and the desired surface finish. Proper selection and control of these parameters are crucial for achieving efficient material removal, preventing tool breakage, and ensuring the quality of the finished part.
