Exploring Metal Cutting Methods: Beyond the Blade

Metal cutting is a crucial manufacturing process that shapes metal materials into various components and products. Recent technological advancements have introduced innovative metal-cutting methods beyond traditional blades and cutting tools. These innovative methods go beyond the limitations of blades, offering increased precision, efficiency, and versatility. In this blog, we will explore these cutting-edge methods of metal cutting and their advantages in the manufacturing industry.

Different metal-cutting methods

The cutting method works to cause a fracture in the metal that is processed. You can explore the top fabrication techniques used in the industry. We can classify metal cutting into broad categories:

Chip forming

Chip forming is a metal-cutting process that employs mechanical tools to remove material from a workpiece. In chip forming, we remove material gradually from the workpiece in small pieces, or “chips.” There are various operations that fall under the umbrella of chip forming, each utilizing the process to remove excess material. Here’s a brief overview of a few:


Turning -Chip Forming section, Metal cutting Blog

Turning is a fundamental cutting technique that uses a rotating workpiece and cutting tool to produce cylindrical shapes. The worker positions the cutting tool along the axis of rotation, and the material is chipped slowly from the workpiece. 


Drilling -chip forming section

Fabricators use drilling machines to produce round holes. Rotating drill bits gradually enlarge a hole as they penetrate the workpiece.


Milling - chip forming section

Milling is a versatile metal-cutting process that removes material from a workpiece by moving a cutting tool across its surface. This versatile process produces a wide range of shapes, including flat surfaces, slots, pockets, and contours.


Sawing is a multipurpose metal-cutting technique that uses a revolving metal-cutting blade with teeth to cut through several materials and forms. The metalworking, woodworking, and construction sectors frequently employ this technique. 

Shearing Machine

Shearing process - metal cutting blog

A shearing machine, also known as a steel plate shearer, is a metal cutting machine that utilizes two blades, one moving linearly against the other, to cut sheet metal. It is primarily used for the straight-line cutting of metal plates.

Abrasive material removal

Abrasive material removal is a technique that utilizes hard, abrasive particles, often in the form of a rotating wheel or a high-pressure water jet, to remove material from a surface. It is used for several applications, including cleaning, cutting, polishing, and grinding. It can also produce highly precise surface finishes.


Grinding - abrasive material removal - Metal Cutting Methods

Grinding, a precision metal-cutting technique, utilizes an abrasive wheel to remove tiny amounts of material from a workpiece. We use this process to achieve precise dimensions, remove surface flaws, and finish the workpiece.

Water jet cutting

A water jet cutter uses an extremely high-pressure jet of water that is sometimes mixed with abrasive substances to cut a wide range of materials. It is a cold-cutting method and is perfect for cutting materials that are heat sensitive like aluminium and plastic.


Metal cutting using heat involves employing various heat sources, such as electric arcs, radiation energy, or exothermic reactions, to separate metal pieces. Thermal cutting, air carbon arc cutting, plasma arc cutting, electron beam cutting, and laser beam cutting are examples of this method. These processes offer high speed and precision in cutting metals of varying types and thicknesses.

Flame Cutting

Automatic flame cutting method - heat section

Flame cutting, also known as gas cutting, is the oldest thermal cutting method. It has evolved from acetylene gas cutting and propane cutting to the now widely used natural gas cutting. Flame-cutting equipment is relatively inexpensive and can handle thick steel plates.

Laser Cutting

Laser cutting uses high-energy laser beams to vaporize and cut through material. This process offers exceptional accuracy, minimal heat distortion, and the ability to cut intricate shapes in a wide range of materials, including metals, plastics, ceramics, and composites. 

Plasma cutting

Plasma cutting is a versatile metal cutting process that employs a high-velocity jet of ionized hot gas, known as plasma, to melt and remove material from a workpiece. This process provides high cutting speeds, minimal heat-affected zones, and the ability to handle a variety of materials, including thick and conductive metals, such as steel, aluminium, and copper.


EDM machine

Electrochemical cutting methods involve the use of electrical and chemical reactions to remove material from a workpiece. Some common electrochemical cutting methods include electrical discharge machining (EDM), etching, and electrochemical machining (ECM).

This process involves passing a strong electric current through an electrolyte solution between an electrode (tool) and the workpiece (anode). At the anode, the metal dissolves and transforms into metal ions, which are then carried away by the electrolyte.
