CNC machining is a sophisticated process involving various machine tools, materials, cutting tools, and methods. Drawing from extensive experience in actual production processes, we share valuable tips for optimizing CNC machining tools. These insights cover determining cutter points, selecting tool paths, and choosing the right CNC machining tools for different applications.

Tip 1: Determining Cutter Points in CNC Machining Tools

Set the cutter point on the part to be processed, ensuring it is a reference position or a finished point.

Establish a relative cutter point position with a fixed dimension relationship to the positioning reference.

Selection Principles:

Easy to find

Easy programming

Small cutter point error

Convenient inspection during processing

Set the origin position of the workpiece coordinate system based on the cutter point after clamping, ensuring consistency with the programming coordinate system.

Tip 2: Selecting Tool Paths in CNC Machining Tools

Consider the machining accuracy requirements of parts when determining the tool path.

Seek the shortest processing path to reduce empty tool time and improve efficiency.

Reduce the number of program segments.

Ensure continuous processing of the final contour using the last tool to maintain workpiece contour surface roughness.

Carefully consider the forward and backward path of the tool to minimize tool marks and avoid scratching the workpiece during vertical cutting.

Tip 3: Choosing CNC Machining Tools

Select a non-regrinding carbide end milling cutter for plane milling.

Use end milling cutters for rough milling and continuous cutting along the workpiece surface.

Utilize ball cutters and round cutters for curved surfaces and variable bevel profiles.

Adjust cutting parameters (cutting depth, spindle speed, and feed speed) based on the general principle of less cutting and fast feeding.
