Engineering Drawing
General Assembly Drawings An assembly drawing (see Figure 1) represents the relative position and/or shape of a group of assembled parts. It also depicts the constituents of a parts list.A list of parts is often provided in a separate document, i.e. a parts list, but can be included within the
Axes on a cnc machine
Understanding Axes on a CNC Machine Computer Numerical Control (CNC) machines are the backbone of modern manufacturing, transforming digital designs into precise physical parts. At the core of their functionality are the axes of motion, which dictate how the cutting tool and workpiece move relative to each other. Let’s break
Stepper Motor
Stepper Motor Basics A stepper motor is an electric motor whose main feature is that its shaft rotates by performing steps, that is, by moving by a fixed number of degrees. This feature is obtained thanks to the internal structure of the motor and allows to know the exact angular
Arduino
Arduino Uno The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. The microcontroller board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and
CNC PROGRAM
Structure and contents of an CNC program An NC (Numerical Control) program is a set of instructions used to control the movements of a machine tool or a machining process. These programs are typically written in a language understood by the specific CNC (Computer Numerical Control) machine being used. Blocks
RS-232 protocol
The protocol RS232 defines the signals used in communication, and the hardware to transfer signals between devices.The time diagram of the typical signal used to transfer character ‘A’ (ASCII: 6510 or 0x41) from device A to device B is given in fig.1 and would appear on the upper line TX
