1. The aim of this project is to understand the functioning of a CNC machine.
2. CNC machining is a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery. The process can be used to control a range of complex machinery, from grinders and lathes to mills and routers. With CNC machining, three-dimensional cutting tasks can be accomplished in a single set of prompts.
CNC Machining
3. When a CNC system is activated, the desired cuts are programmed into the software and dictated to corresponding tools and machinery, which carry out the dimensional tasks as specified, much like a robot.
4. In CNC, machines are operated via numerical control, wherein a software program is designated to control an object. The language behind CNC machining is alternately referred to as G-code, and it’s written to control the various behaviors of a corresponding machine, such as the speed, feed rate and coordination.
5. In CNC machining, movement is usually directed across X and Y axes. The tool, in turn, is positioned and guided via stepper or servo motors, which replicate exact movements as determined by the G-code. If the force and speed are minimal, the process can be run via open-loop control.
6. The basic working of any CNC Machine is as shown in the link below.
Methodology
7. The CNC Machine available in MAKERSPACE is compatible with ASPIRE software. This software provides a powerful but intuitive tool to create intrinsic designs as developed in any CAD software. It develops a 2D path for tool movement to undertake different processes like Profiling, Pocketing, and Drilling as well as 2.5D toolpaths including; V-Carving, Prism carving, Moulding Toolpaths, Fluting and even a decorative texturing strategy. The CNC machine present in the department has a hand held control to position the tool or setting the origin for begining the operation.
8. A CAD drawing is uploaded onto the ASPIRE software and a G code is developed. The G-code is uploaded onto the CNC machine to undertake the cutting process.
9. The origin of the tool is set at the start of the process and the job is commemced.
