Too low or too high SFM settings will have a negative impact on the quality of machined parts and cutting tools. How to set the best SFM in machining? In this article, we’ll dive into the SFM meaning and definition, as well as its units, formula, calculation, chart, and conversion between RPM. What Is SFM in Machining – SFM Meaning and Definition In CNC machining, SFM stands for surface feet per minute and defines the relative linear velocity between the cutting edge of a tool and the workpiece. SFM is a common unit of measurement for cutting speed in machining and is primarily us......

A clearance hole is necessary to permit a fastener to pass through a material without its threads gripping into it, what size should a clearance hole be for different fasteners such as a M4 screw or a 3/8 bolt. To determine its diameter, check out the clearance hole size chart for metric and imperial bolts, screws, and studs according to ASME B18.2.8 standard. What Is Clearance Hole? A clearance hole is a specific type of hole drilled in a material that is designed to allow a threaded fastener to pass through without engaging the threads. Is is distinct from a tapping drill hole, which ......

The chatter in CNC machining can be a pervasive issue, affecting surface quality, tool life, and operational efficiency. Here, we’ll explore the phenomena of chatter, its causes, and practical strategies to mitigate its effects across various CNC machining processes including turning, milling, drilling, and cutting. 1. What is Chatter in Machining? The chatter in machining, also known as vibration, refers to the vibration phenomenon in the cutting operation of machining processes such as CNC milling, turning, drilling, etc., which generates waves on the surface of the ma......

Straight turning is one of the turning processes that can be performed on a lathe machine, how does it work, and how to complete the operation? This article will explain the straight (plain) turning about its principle, uses, operation, tools, diagram, and differences compared to step turning. What Is Straight Turning in Lathe Machine? Straight turning, also known as plain turning or cylindrical turning, is a fundamental lathe operation where a workpiece secured in a chuck, rotates about its axis while a cutting tool moves parallel to this axis. Plain turning is a specialized technique o......

Rotary table milling machines, while not as common as standard milling machines, still have unique benefits and specific applications in modern manufacturing. Here we’ll introduce the rotary table milling machine with its definition, parts, diagram, and how to use it. What Is a Rotary Table Milling Machine?
