avCNC is an open source CNC machine

avCNC

avCNC - truly open source CNC

avCNC is an attempt to create open source CNC machine aside with an CNC control software.

avCNC consists of 5 parts

• avCNCgui - an graphical front end
• avCNCinterpreter - a CORE that interprets G-code in real time
• avCNCinterpolation - a conponent that runs in realtime to control the serve motor or step motor.
• avCNCinterface - a hardware interface that connect CNC machine and CNC control software.
• avCNCmachine - a CNC machine with stardart set of axis.

avCNCgui

avCNCgui will run on embeded linux with Wayland as display server. so avCNCgui will use Qt as toolkit.

avCNCinterpreter

avCNCinterpreter is controled by avCNCgui. It's mainly for interpreting G-code and turn it into an internal data structure that avCNCinterpolation will relay on.

avCNCinterpolation

avCNCinterpolation is the one that must runs realtime, so we will need an RT-kernel, or we can have avCNCinterpolation run on seperated core. avCNCinterpolation generate motor control signal to drive motors on the CNC machine.

avCNCinterface

this is not an program ,but a protocol that avCNCinterpolation used to communicate with CNC machine

avCNCmachine

this is not an program, but an CAD design that shows how an standard 5 axis CNC machine with avCNCinterface is .

插补器原理

插补器是 avCNC 的核心。avCNC 的插补器分成两个部分，一个使用数字积分法得出插补路径。另一个则利用定时器输出所需的插补脉冲
