What is walking heart machining?

 What is walking heart machining?

Machining is a prototyping and manufacturing process that creates the desired shape by removing unwanted substances from larger pieces of material. 

Since parts are constructed by removing material, this process is also called subtractive manufacturing. For information on additive manufacturing, read the FAQ on rapid prototyping.

What are the different types of processing?

Various processing techniques have existed for decades, but most of them belong to three main processes, each of which requires specific tools and experienced mechanics. they are:

  • Turning-Turning or turning involves rotating the workpiece on the machine while the single-edged cutting tool remains stationary. The cutting tool moves slowly parallel to the rotation axis of the workpiece to remove material.
  • Drilling-Drilling creates a round hole by rotating a cylindrical tool parallel to the axis of rotation of the workpiece. The diameter of the created hole is equal to the diameter of the tool used.
  • Milling-Milling is the process of removing material from a workpiece using a rotating tool with a feed motion perpendicular to the rotation axis of the cutting tool. This is one of the common processing forms used today.

How does machining work?

In modern product development, machining is often done using CNC machines, which stands for computer digital control. Essentially, the machine uses computer software to obtain a CAD design model and draw a tool path, thereby transforming the design into a 3D machined part. CNC can use a variety of materials to make parts, and make various types of finishes, and the tolerance should be the closest to 0.001 inches of the solid material. Unlike rapid prototyping, parts are processed using real materials, reflecting the density, surface treatment and porosity of the final design. Machined parts can be used for representative tests. Sliding parts including friction factors and sealing parts requiring O-rings and sealing surfaces can be used for model tests.

What are the advantages of processing?

  • A variety of finishes and materials to choose from
  • Tolerance is even smaller to .001"
  • Real material and real density

What are the disadvantages of processing?

Can only be used from one side at a time. Need to manually rotate and reposition objects

Need a skilled mechanic

Material and processing time can be expensive
