Factors Affecting Feed Force
1)Feed Rate: Increasing the feed rate generally increases the feed force due to the higher material removal rate.
2)Depth of Cut: A deeper cut increases the volume of material being removed, thus increasing the feed force.
3)Workpiece Material: Harder or tougher materials typically generate higher feed forces.
4)Tool Geometry: The rake angle, clearance angle, and edge radius of the cutting tool affect the feed force. For example, a positive rake angle usually reduces the feed force.
5)Cutting Speed: Higher cutting speeds can sometimes reduce feed force due to thermal softening of the workpiece material, but this is not always the case.
6)Tool Wear: As the tool wears, the cutting edge degrades, leading to increased friction and higher feed forces.
How to Calculate Feed Force?
Feed Force calculator uses Feed Force = Thrust Force*cos(Side Cutting Edge Angle) to calculate the Feed Force, Feed force, also known as thrust force or axial force, is one of the three primary forces acting on a cutting tool during a metal cutting operation. It acts in the direction of the feed motion, pushing the tool into the workpiece. Understanding feed force is crucial for optimizing cutting conditions, ensuring tool longevity, and achieving desired surface finish and dimensional accuracy. Feed Force is denoted by Ff symbol.
How to calculate Feed Force using this online calculator? To use this online calculator for Feed Force, enter Thrust Force (Ft) & Side Cutting Edge Angle (ψ) and hit the calculate button. Here is how the Feed Force calculation can be explained with given input values -> 1.07797 = 6.29*cos(0.9625508278).
