Stone engraving machine is a processing system which can load NC engraving program and automatically control the movement of engraving machine. It usually consists of engraving program calculation system and NC system.

其工作原理是：計(jì)算機(jī)通過(guò)雕刻軟件將需要的雕刻的圖形數(shù)字化，生成每個(gè)步驟的雕刻程序(一般為G代碼、HPGL格式文件)，通過(guò)USB接口或其他數(shù)據(jù)傳輸接口(RS232、RS485等)傳輸給控制系統(tǒng)，然后控制系統(tǒng)采用特定的算法將輸入的路徑信息轉(zhuǎn)化為數(shù)控信息，控制器把這些信息轉(zhuǎn)化為驅(qū)動(dòng)步進(jìn)電機(jī)或伺服電機(jī)的信號(hào)(脈沖串)，控制雕刻機(jī)X、Y、z三軸的進(jìn)給.

Its working principle is: the computer digitizes the engraving graphics needed by engraving software, generates the engraving program of each step (generally G code, HPGL format file), and transmits it to the control system through USB interface or other data transmission interfaces (RS232, RS485, etc.), and then the control system uses a specific algorithm to convert the input path information into numerical control information, and the controller converts these information The information is converted into signals (pulse train) to drive stepper motor or servo motor to control the feeding of X, y and Z axes of engraving machine

同時(shí)，石材雕刻機(jī)的高速旋轉(zhuǎn)主軸帶動(dòng)按加工材質(zhì)配備的刀具，對(duì)固定于機(jī)械本體的工件進(jìn)行銑削，即可雕刻出在計(jì)算機(jī)上設(shè)計(jì)的各種平面或立體圖形文字，實(shí)現(xiàn)雕刻的自動(dòng)化加工。

At the same time, the high-speed rotating spindle of the stone carving machine drives the cutting tool equipped according to the processing material to mill the workpiece fixed on the machine body, which can carve out various plane or three-dimensional graphics and characters designed on the computer, and realize the automatic processing of carving.

由本系統(tǒng)的設(shè)計(jì)指標(biāo)可知，其目標(biāo)是設(shè)計(jì)開(kāi)發(fā)一套針對(duì)石材雕刻機(jī)的控制特點(diǎn)，能滿足石材雕刻機(jī)控制需求并具有高性價(jià)比的普及型中檔的嵌入式雕刻機(jī)數(shù)控系統(tǒng)。因此，本系統(tǒng)需要從速度方面入手，解決好運(yùn)動(dòng)的快速性問(wèn)題，同時(shí)兼顧系統(tǒng)的制造成本，使硬件造價(jià)控制在預(yù)期的范圍內(nèi)?？梢?jiàn)，系統(tǒng)的處理速度和成本控制是本系統(tǒng)方案設(shè)計(jì)應(yīng)考慮的。

According to the design index of this system, the goal is to design and develop a set of popular and middle-class CNC system for stone carving machine, which can meet the control requirements of stone carving machine and has high cost performance. Therefore, the system needs to start from the speed, focus on solving the problem of fast movement, and take into account the manufacturing cost of the system, so that the hardware cost can be controlled in the expected range. It can be seen that the processing speed and cost control of the system are the key points to be considered in the scheme design of the system.

根據(jù)現(xiàn)有數(shù)控技術(shù)的發(fā)展水平，目前提高數(shù)控系統(tǒng)處理速度的途徑有以下幾種：

According to the current development level of CNC technology, there are several ways to improve the processing speed of CNC system

1)PC+高速運(yùn)動(dòng)控制卡；

1) PC + high speed motion control card;

2）由高性能通用CPU，如X86、Pentium等組成的工控板；

2) Industrial control board composed of high-performance general-purpose CPU, such as x86, Pentium, etc;

3）高速運(yùn)動(dòng)控制芯片；

3) High speed motion control chip;

4）采用ARM等高性能單片機(jī)替代高速運(yùn)動(dòng)控制芯片；

4) High performance MCU such as arm is used to replace high-speed motion control chip;

相信通過(guò)小編的介紹，您對(duì)于石材雕刻機(jī)有了更深層的了解。
