This tool \u003cstrong\u003ecuts into the cylinder taken initially as the base workpiece to carry out the machining process.\u003c\/strong\u003e This operation is repetitive, or patterned, and is known as part milling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlaning machine: \u003c\/strong\u003e a device that \u003cstrong\u003ehas a cutting edge positioned perpendicular to the direction of movement.\u003c\/strong\u003e The segment that performs the cutting or machining also matches the area of the tooth gap of the gear to be cut.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eBy generation\u003c\/h5\u003e\n\u003cp\u003eThis type of gear cutting machine delivers great accuracy in the work done on the workpiece.

In this case, \u003cstrong\u003eit uses as its tool a screw with straight teeth, \u003c\/strong\u003ewhile its axis is offset by the same amount as the lead angle of the screw helix. This method is one of the most widely used in industry.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWith a rack cutter: \u003c\/strong\u003e during this process or method, the machine produces both tooth profiles simultaneously, and for this it uses a \u003cstrong\u003erack-shaped tool with a module exactly matching the gear to be cut.\u003c\/strong\u003e The cut is made with reciprocating movements of the tool, in step with the axis of the cylinder taken as the base workpiece. Although it is not a continuous machining process and requires the tool to be repositioned, it is also one of the most common processes because of how widely it is used.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWith a pinion cutter:\u003c\/strong\u003e the machinery carries out a continuous machining process in which the cutting tool does not need to be repositioned. \u003cstrong\u003eThe cut is made by a wheel or thread with sharpened teeth, while it rotates on the cylindrical base\u003c\/strong\u003e that is the object of the cutting process. Making this generating pinion is complex, and any defects it may have are transferred to the workpiece being machined, since, in general, they are reproduced very easily.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWith planing:\u003c\/strong\u003e in this case the machine uses a \u003cstrong\u003eflat-profile cutting tool,\u003c\/strong\u003e whose characteristic movement when machining the workpiece is reciprocating.
