  • Un-tether Your Encoder: Go Wireless
    conditioning electronics and read-out devices. In most cases, machine designers can work around the annoyances and limitations that numerous wires and unreliable connectors pose. But in some installations, such as cranes, rotating tables, and mobile applications, it certainly would be nice if wires
  • Machining - Five-Axis Machining: What Are The Benefits and How Can You Achieve this Capability? - 09/07
    applications and needs that determine how a given manufacturer gets the job done. In both vertical and horizontal milling, two additional axes are added to the existing X, Y and Z axes. These two axes are typically a rotary axis that rotates around the Z axis and a tilting axis that rotates around the Y
  • Steering Gear Manipulator for Dunnage Loading
    on the rear shelves. The tooling design was further constrained by the fact that access to the completed part was limited to a small portion of the upper surface due to dunnage rack and assembly table interferences. Furthermore, the part needed to be rotated 16° to seat properly in the dunnage
  • IFPAC 2006 Under the Microscope
    By Emil W. Ciurczak, Chief Technical Officer, Cadrai Group Aspectrics (Pleasanton, Calif.) introduced a nifty Encoded Photometrics Infrared Spectroscopy (EP-IR) device. This device contains a rotating encoder disc that can measure up to 256 specific channels simultaneously, moving at a rate

    the mouse, the ball grips the table or pad surface and rolls accordingly with the ball's motion being transmitted to the two rollers. Each roller then rotates a spoked wheel, or chopper, which passes through an infrared beam. Each breaking of the beam indicates a set amount of movement. (Exactly how
  • Efficient Fixed-Point Trigonometry Using CORDIC Functions for PIC16F
    AN1061 Efficient Fixed-Point Trigonometry Using CORDIC Functions For PIC16F TABLE 1: SIN(x) FUNCTION CALL Author: Jose Benavides SPECIFICATIONS WITH Microchip Technology Inc. PIC16F877A AT 20 MHZ CORDIC in asm Math.h in C INTRODUCTION Time 370 µs1.9 ms This application note presents
  • How Does an Optical Encoder Work?
    The Optical Encoders typically consist of a rotating and a stationary member. The rotor is usually a metal, glass, or a plastic disc mounted on the encoder shaft. The disc has some kind of optical pattern, which is electronically decoded to generate position information. The rotor disc in absolute

    the nut from rotating. The stepper motor rotates the leadscrew, which causes the external nut (and the connected load) to move in a precise linear motion. A typical application includes a positioning table, sample handling system or pick-and-place system that requires precise positioning. Notably
