    Determining the location of our fixture in space may seem like a simple task but if our goal is precision then we need to know exactly where our platform and ball screw are located at all times. To accomplish this goal, we will need to use a combination of encoders and dial gages to keep position and to check our position and precision. Encoder/Glass Scale A linear encoder is the typical way that CNC machines measure motion. It’s electro-mechanical device that creates digital signals that correlate to a position, a velocity, and a direction along a path. A linear encoder acts as a sensor and when linked to a scale it encodes a position. The sensor reads the scale and converts the encoded position into a meaningful value in the form of a digital or an analog readout. Optical linear encoders utilize a combination of light, lenses, photosensors, and a glass scale. The light source in conjunction with a lens creates a beam of light, which passes through a scanning reticle and then through the glass scale. That light is then picked up by photosensors, which creates a type of sine wave output, which the linear encoder interprets (Figure 5, Anaheim Automation, 2016). The level of accuracy created in this system is very high but the glass scale and…

Now since our brains don’t function like a video camera perfectly capturing every moment of our lives, we have to work earnestly in order to remember every minute detail which is deemed important or necessary. This is where…
