The cutting tool material used for cutting must have sufficient hardness (The basic requirement that the cutting material is harder than the workpiece material.), toughness (Needed to prevent breaking and crack formation. Is equivalent to the flexural strength of the material under the conditions that are present, together with its break resistance. Toughness is highly

The ISO designation system (ISO 1832) standardizes the naming of indexable inserts, representing each important feature and dimension using a code system. This unique code becomes the insert’s name. Unique naming of indexable inserts, independent of the supplier. Clear inclusion of all important features and dimensions in the name. Some code positions correspond to the

Aluminum alloy is an alloy primarily composed of aluminum as the base metal with the addition of certain amounts of other alloying elements. The main alloying elements include copper, silicon, magnesium, zinc, and manganese, while the secondary alloying elements include nickel, iron, titanium, chromium, lithium, and others. Aluminum alloys have a low density (approximately 2.63-2.85

IT grade(s) refer to an internationally accepted code system for tolerances on linear dimensions. Such code systems may be used to produce interchangeable parts. In engineering, the word tolerance refers to a range of allowable dimensions or values. Standard tolerance grades are a group of tolerances for linear sizes characterized by a common identifier. For

Accurately describing the failure modes of cutting tools is crucial for effective communication in the field of machining technology. The key aspect in determining the failure modes of cutting inserts is to identify their initial failure mode. In other words, it is necessary to make assessments when the cutting insert first exhibits signs of a

Notching, primarily occurring on the trailing face of the main cutting edge, typically appears at the edge of the contact area between the cutting edge and the chip. This is the part of the cutting edge that makes contact with the workpiece surface. In this region of the cutting edge under high-temperature conditions, it is

When cutting ductile materials within a certain cutting speed range, the workpiece material continuously accumulates and adheres near the cutting edge on the front face of the tool. In some cases, it may even weld onto the cutting edge of the tool, forming a built-up edge (BUE), commonly known as a “chip lump” or “tool
