数控VB编程，生成NC代码 数据溢出怎么办？
像都是源码可以用来模具雕刻的软件
法国Type3软件是当今世界上最优秀的专业雕刻软件之一，它拥有强大的源码功能——三维、曲面、源码浮雕、源码ppt宝藏网源码投影、源码设定各种刀具路径
精雕软件还有别的源码TYPE3或是ARTCAM也可以做浮雕的
奈凯推出NC－雕铣机控制系统，该数控系统全面支持精雕各种版本Eng文件，源码该功能是源码针对用户对精雕JDPaintV5.这一排版软件的酷爱而研发的。
精雕公司自主开发了精雕CNC雕刻系统，源码该系统由三大部分组成，源码即精雕雕刻CAD/CAM软件即JDPaint软件、源码rps 源码精雕数控系统、源码机械本体三大部分。源码该系统的使用通过两台计算机完成，一台是加工编程计算机，另一台是数控控制计算机。两台计算机运行两个不同的unet源码程序需要相互交换数据，即通过数据文件进行。具体是：JDPaint软件通过加工编程计算机运行生成Eng格式的数据文件，再由运行于数控控制计算机上的控制软件接收该数据文件，将其变成加工指令。
此外，JDPaint软件与Ncstudio软件不具有同一性，Tsung源码JDPaint软件输出的Eng文件是数据文件，采用Eng格式。Ncstudio软件能够读取原告JDPaint软件输出的Eng文件，即Ncstudio软件与JDPaint软件所输出的Eng文件兼容。

添加了G指令，用于同步参数和当前位置
V5.4.6
改进软限位算法，该算法避免紧停式的突然停止，而是通过内部调整倍率实现缓慢停止
把“执行加工指令”对话框中的“刀具半径”改为“刀具直径”
V5.4.7
添加了#SSCURWORKCOOR0, #SSCURWORKCOOR1, #SSCURWORKCOOR2变量，用于访问当前点的工件坐标
校正刀杆长度功能的第一次对刀和第二次对刀采用最新的指令取代了旧的两步式指令，更简洁
在文件管理窗口中文件大小右对齐，并且每千位用逗号分隔
手动步进窗口中小键盘上快捷键功能不再受数字锁的影响
V5.4.
更正了TraceView偶尔不能及时刷新的错误
改进了MaskEdit的编辑性能
