The basis for selecting the milling cutter

I. Properties of the Material to Be Cut

The objects of wood cutting are solid wood and wood composite materials. Solid wood can be further classified into softwood, hardwood and treated wood, etc.; wood composite materials include plywood, veneer laminated board, particle board, oriented strand board, large particle board, gypsum particle board, cement particle board, hard fiberboard, medium density fiberboard, high density fiberboard, fine woodwork board, glued composite materials, etc. Some wood or wood composite material workpieces may also undergo single-sided or double-sided veneering decoration treatment.

II. Cutting Direction

When cutting solid wood, the wood is divided into longitudinal, transverse, end-direction, longitudinal-end-direction, longitudinal-transverse, and transverse-end-direction cuts according to the direction in which the blade is relative to the wood fibers.

III. Rotation Direction and Feed Direction of the Cutting Tool

Based on the rotation direction of the machine tool's tool axis and the feed direction of the wood workpiece, determine the inclination direction of the cutting edge on the tool.

IV. Stability of Cutting Tools and Workpieces

The stability of the cutting tool and the workpiece during the cutting process includes several aspects. The stability of the workpiece in an automatic four-sided sanding machine refers to the fact that the wood workpiece feeds smoothly without any jitter during the cutting process. The measures taken to enhance the stability of the workpiece mainly include reducing the center of gravity of the workpiece and increasing the contact area.

V. Requirements for Surface Finish of the Processed Products

The surface quality of wood workpieces includes surface roughness, geometric dimensions and shape position accuracy.
