Cutting tool fundamentals
Depending on the characteristics (hardness and toughness) of the tool material, various types are used.
Hardness: The harder it is, the less likely it is to wear, but it is easy to break and chipping .
Toughness: The tougher it is, the harder it is to break, and the harder it is to chipping . If it is tough, it is easy

< Basics of Cutting (4) >, we will introduce "metal materials" among the main types of workpiece materials.
"Metal materials" can be roughly divided into "iron and steel" and "non-ferrous metals".
"Non-ferrous metals" include aluminum alloys and copper.
"Steel" is a general term for metal materials with iron as the main component.

There are various materials (= materials, workpiece materials) in the world, but they are classified according to the nature of the workpiece material.
Workpieces are broadly classified into " metallic materials " and " non-metallic materials ".
Typical examples of "non-metallic materials" include wood, paper, and plastic.

In general, how much harder should a cutting tool be than the material?
The approximate hardness of the workpiece material that can be processed is as follows.
・ Difference in hardness for stable machining: tool hardness -40HRC
・ Hardness difference that can be managed to be processed: Tool hardness -20HRC
The hardness

Cutting tool fundamentals
"Screw removal" is the process of re-cutting a screw that has already been completed using a tool such as a tap or a threading round die to remove rust or adjust distortion.
It is carried out when correcting the screws that the bolts were in during machine maintenance.
In internal thread , it is common to u
