Practice has proved that the actual processing of grease with a single processing program and process accumulation still has its merits. Because the operator does not have a clear understanding of the content of the program and does not fully understand the intention of the programmer, the programmer often needs to explain, explain and guide verbally on the spot. Yes, but if the program is for long-term mass production, it is difficult for programmers to be on site at all times. In addition, if the programmer is temporarily absent or transferred, and the familiar operator is not present or transferred, the trouble will be even more, and it will even cause a quality accident or a temporary stoppage of production. Therefore, it is very useful to give the necessary detailed description of the processing program, especially for those programs that need to be stored and used for a long time.
According to the application practice, the main contents of the adding program are explained as follows: ①The model number of the CNC machining equipment used and the model of the control machine;
② Tool setting point (program origin) and allowable tool setting error;
③ The coordinate direction and position of the workpiece relative to the machine tool (represented by Deli);
④ Symmetrical axis used for mirror processing;
⑤ For the specifications of the tools used, the drawing numbers and their corresponding tool numbers in the program, the compensation value must be increased or decreased according to the actual tool radius or length (for example, when using the same program and the same tool for roughing) , increase the tool radius compensation value), the block number for changing the tool, etc.;
⑥ The order of the processing content of the whole program (equivalent to the content description and the sequence of work steps), so that the operator can understand what to do first and what to do later;
⑦ Subroutine description, the content of the subroutine programmed into the program should be explained, so that people can understand the function of each subroutine;
⑧ Other issues that need special explanation, such as the block number of planned stop for the tight point (moving platen) that needs to be replaced during processing, the block number of planned stop for intermediate measurement, the maximum allowable tool radius and length. Wait.

At,we use advanced equipment to offer you Unparalleled precision for producing metal and plastic machining parts

  • We combine the latest CNC milling and turning processes with proprietary technology to deliver high quality, on-demand parts.
  • Our team of engineers and machinists program the equipment to optimize cutting time, surface finish, and final tolerance to meet your design specifications
  • We specialize in cnc precision machining, single part prototyping, short to medium production runs, manufacture parts on time, every time, so you can stay ahead of schedule
  • CNC machining can create very similar parts to series parts. It is often more efficient and faster than other rapid prototyping technologies for the manufacture of a quantity of prototypes between 1 and 10 parts . We also recommend CNC machining for parts with large sizes (greater than 600 mm).
