UG programming refers to the use of professional 3D software UGNX developed by Siemens to compile the digital program of CNC machine tools.

CNC machine tools can't move without programs. Professionals need to use professional software tools to program according to the shape of products. UG programming refers to the programming of CNC machine tools.

UG is the most advanced and tightly integrated CAID/CAD/CAE/CAM software system in the world, which provides a complete set of solutions from product design, analysis, simulation to NC program generation. UG CAM is the whole UG system.

Brief introduction of CAM module

Some of them, based on the three-dimensional master model, have powerful and reliable tool path generation methods, which can complete milling (2.5-5 axis), turning, wire cutting and other programming. UG CAM is the most representative NC programming software in mold NC industry. Its biggest feature is that the generated tool path is reasonable and the cutting load is uniform, which is suitable for high-speed machining. In addition, the model, machining technology and tool management during machining are all related to the master model. After the design of the main model changes, the programming only needs to be recalculated, so the efficiency of UG programming is very high.

UG CAM mainly consists of five modules, namely interactive process parameter input module, tool path generation module, tool path editing module, 3D machining dynamic simulation module and post-processing module. The following is a brief introduction to these five modules.

(1) interactive process parameter input module. Through human-computer interaction, the process parameters such as tools, fixtures, programming origin, blanks and parts are input in the form of dialog boxes and process guides.

(2) Tool path generation module. There are many ways to generate tool path, including milling (2.5-5 axis), turning, wire cutting and other processing methods. This book mainly explains 2.5-axis and 3-axis CNC milling.

(3) Tool path editing module. The tool path editor can be used to observe the tool path and provide the function of extending, shortening and modifying the tool path. At the same time, you can edit the tool path by controlling the information of graphics and text.

(4) 3D machining dynamic simulation module. It is a low-cost and high-efficiency method for testing NC machining without using machine tools. You can check whether the tool collides with parts and fixtures, whether it is over-cutting, and the distribution of machining allowance, so as to solve it in time during programming.

(5) Post-processing module. Includes a general post-processor (GPM), and users can easily establish customized post-processing. By using the Machining Data File Generator (MDFG), a series of interactive options prompt users to select parameters that define the characteristics of specific machine tools and controllers, including specifications and types of controllers and machine tools, interpolation methods, standard cycles, etc.

Ug tool path is better. Although there are few parameters, many templates can be set, and even simple workpieces can be programmed automatically.
