NX开发 刀路生成
此段是可以生成程序的完整代码，只有从坐标（10，10，10）到（500，500，500）一根刀轨。
motion_ptr->feed_value 的值为0时生成G00，非0时生成G01。
此代码只有直线，生成圆弧的方法类似，可参考open-api函数库里的ufd_cam_udop.c文件。
加工CAM的入口函数是udop,此入口函数和常用的UG二次开发入口函数ufusr并列，不需要在ufusr中调用，直接在ufusr所在的CPP文件中写入udop函数即可，或者将udop放在一单独的.c文件中，在ufusr所在的CPP文件中包含也可以，#include "path.c"。
编译出来的dll文件不能像普通的二次开发文件一样直接用Crtl + U 调用，必须先在ugii_env.dat文件中定义好变量，例如abs=d:\path.dll。此abc即是变量，然后使用UG的自定义加工模板调用此变量就OK了。
#include <uf_defs.h>
#include <uf_cam.h>
#include <uf_udop.h>
#include <uf_oper.h>
#include <uf_path.h>
#include <uf.h>
#include <uf_exit.h>
#include <stdio.h> extern void udop(char *param, int *status, int parm_len)
{
char op_name[UF_OPER_OPNAME_LEN];
UF_UDOP_id_t udop_id;
UF_UDOP_purpose_t purpose;
UF_OPER_id_t oper_id;
UF_PATH_id_t path_id; UF_CAM_exit_id_t exit_id = (UF_CAM_exit_id_t)param;
UF_initialize();
UF_UDOP_ask_udop( exit_id, &udop_id);
UF_UDOP_ask_oper( udop_id, &oper_id);
UF_UDOP_ask_purpose( udop_id, &purpose);
UF_OPER_ask_name( oper_id, op_name);
UF_OPER_ask_path( oper_id, &path_id); if( purpose == UF_UDOP_GENERATE )
{ /************ To input GOTO/ motion*************/
UF_PATH_linear_motion_t motion,*motion_ptr = &motion;
motion_ptr->feed_value = 0.0;
motion_ptr->feed_unit = UF_PATH_FEED_UNIT_NONE;
motion_ptr->type = UF_PATH_MOTION_TYPE_CUT;
motion_ptr->tool_axis[0] =0.0;
motion_ptr->tool_axis[1] =0.0;
motion_ptr->tool_axis[2] =1.0; motion_ptr->position[0] =10.0;
motion_ptr->position[1] =10.0;
motion_ptr->position[2] =10.0;
UF_PATH_create_linear_motion( path_id, motion_ptr);
motion_ptr->position[0] =500.0;
motion_ptr->position[1] =500.0;
motion_ptr->position[2] =500.0;
UF_PATH_create_linear_motion( path_id, motion_ptr); UF_PATH_cutcom_t cutcom_data;
cutcom_data.cutcom_mode = UF_PATH_CUTCOM_ON;
cutcom_data.plane_type = UF_PATH_PLANE_TYPE_XY;
cutcom_data.cutcom_on_status =
UF_PATH_CUTCOM_ON_BEFORE_ENGAGE;
cutcom_data.cutcom_off_status =
UF_PATH_CUTCOM_OFF_AFTER_RETRACT;
cutcom_data.adjust_register = 2;
cutcom_data.full_cutcom_output = TRUE;
cutcom_data.adjust_flag = TRUE;
UF_PATH_create_cutcom( path_id, &cutcom_data, NULL ); UF_PATH_end_tool_path( path_id );
}
UF_terminate();

File description: Sample NX/Open Application
This is basic example of how to write a UDOP entry in CS
To use this after you build the dll as cs_udop.dll
1) Put the dll in a folder - for example c:\my_udops\
2) Create an system environment variable MYCORP_UDOP_2 and set it to
c:\my_udops\cs_udop.dll
3) Now in NX CAM create a MILL_USER and in the UI enter MYCORP_UDOP_2
for the "CAM API Exit Name in the user interface
press either "User Parameters" or "Generate" to see the results
