CNC machine tools for AutoCAD graphics processing direct programming

Handling code and the auxiliary function F, S and T commands; c. Output module, the system offers a variety of output requirements,[link widoczny dla zalogowanych], such as CRT display part program, such as printed on the printer list; d. Analogue graphics capabilities to allow users to intuitively understand the programmed correctly, the icon in the tool path on the CRT trace is an effective regulatory approach. Here are some parts from the diagram in Figure 1 to obtain information directly XK0816A CNC milling machining process.

Therefore, many CNC machine tools and industrial control equipment is RS422 interface, the transmission rate is more than 20kbit / s, which uses two wires to transmit the signal, if one line is logic \... 0 state, and vice versa. Because the voltage loop is a two-way, thus greatly improving the communication performance, if the data transfer rate limited to 100kbit / s, the cable length allows the 1200m, which is RS232 can not match. Therefore need to transform the shake machine interface,[link widoczny dla zalogowanych], making it into a RS422 interface to meet the requirements of the processing site. 4 Conclusion AutoCAD system provided *, DXF files for CNC machining CNC programming tools, can greatly improve efficiency, shorten product development cycles, ease of product upgrading; for the user, does not require that requires additional programming such as computer-aided learning language, due to the reduction of artificial dry to the middle part of the data conversion, while reducing the error rate is indeed a practical approach.
