Cutting force–based analysis and correlative observations on the tool wear in diamond turning of single-crystal silicon

Abstract: The condition of a cutting tool is an important factor to ultraprecision machining processes. Tool wear has a strong influence on the cutting forces, resulting in poor surface roughness and dimensional tolerance of the workpiece, particularly in ultraprecision machining hard brittle materials. This article presents a cutting force–based analysis and correlative observations on diamond tool wear in machining of single-crystal silicon. The Daubechies wavelet (dB3, level 4) was employed to correlate standard devi… Show more

“…There are two broad classifications of diamond, the main features of which are shown in table X. [148] used wavelet transform method to decompose the cutting force signals for real-time tool condition monitoring with a notion that a good understanding of the wear mechanism is an essential step for identifying the measures needed to suppress wear and to enhance the usefulness of tool life.…”

“…The tangential force causes displacements in the direction of cut chip thickness and its variation therefore relates to chatter. These are the reasons why cutting force measurement is an important indicator of tool wear[148]. From the MD simulation perspective, the calculation of the cutting forces using a diatomic pair potential, such as Morse or Lennard Jones function is relatively simpler because the interaction energy will include a pair component which is defined as the pairwise energy between all pairs of atoms where one atom in the pair is in the first group (workpiece) and the other is in the second group (cutting tool).…”

“…The increase in temperature causes the silicon material to soften and directly causes a reduction in cutting force. Cutting force [40] measurement is an important indicator of nano-cutting behavior. Figure 13 represents average tangential forces (X) and normal forces (Y) calculated with respect to seven different adjustment angles.…”

“…(1) Protecting and enhancing the tool when the measured force is greater than the reference force; (2) Maintaining high productivity when the measured force is less than the reference force, and; (3) The improved reliability of the smart cutting tools in smart machining applications [25]. Figure 18(a) illustrates a block diagram of a CNC machine with adaptive control, where the adaptive control process is based on the smart cutting tool in-process measuring cutting force.…”
