Principles for Selecting the Right Surface Roughness.

The surface of a machined part is uneven, it has tiny peaks and valleys. Surface roughness is the measure of the micro-irregularities on the surface. Surface roughness is closely related to the fitting properties, wear resistance, fatigue strength, contact stiffness, vibration, and noise of mechanical parts.  By far the most commonly used surface roughness parameter …

Up-milling vs Down-milling, Which One to Choose?

Milling is a machining process using rotary cutters to remove material from the workpiece. It has high machining productivity, it is used for a variety of complicated cutting operations, such as slot cutting, threading, drilling, and so on.The machining accuracy can reach to IT9-IT7 generally, and the surface roughness Ra value can be 12.5-1.6um normally. In the milling machining process, …

8 Tips for Machining Titanium Parts

Titanium has properties like high strength, good corrosion resistance, low electrical conductivity, and a very good strength-to-weight ratio. It is widely used in aerospace, medical, automotive, and many more industries.  On other hand, it is easy to be welded to the cutter, likely to work hardening, and with high cutting pressures during the machining process, …

Why 2D Drawing Is Still Important For Manufacturing CNC Machined Parts

The 3D CAD technology makes the parts design and manufacturing process faster. Engineers design the CNC machined parts using CAD software, and send the 3D digital files to the CNC machine shop and the parts will be produced directly from the 3D files using digital manufacturing techniques. No 2D drawing is needed in this design …

What is CNC Machining

What is the difference between CNC, CNC machining, and CNC mahine? CNC, CNC machining, and CNC machine look very similar in words, however, they stand for different things, in this article, we will explain the difference between them in more detail. OK, let’s start. First of all, what does CNC mean?  CNC stands for computer numerical …

CNC machining difference between 3 Axis , 4 Axis,and 5 Axis

CNC machining is a manufacturing process that utilizes computerized controls to operate and manipulate machine and cutting tools to shape stock material—e.g., metal, plastic, wood, foam, composite, etc.—into custom parts and designs. An axis reference is used to describe a CNC machine that works with multiple axis points. The machine operates in the XYZ plane …
