1. Manual programming process: all steps from part pattern analysis and process processing, numerical calculation, writing program sheet, making perforated paper tape to program verification, etc., are all completed manually, which is manual programming.
2. Automatic programming process: The process in which most or all of the programming work is completed by the computer is called automatic programming. The programmer only needs to write a source program in the specified language or input graphic information into the computer according to the part drawing and process requirements, and the computer automatically processes it, calculates the tool center trajectory, writes a list of processing procedures, and automatically prepares it. Into the required control medium. Since the tool path can be drawn automatically by the computer, it is convenient to correct the programming errors in time.
What is the difference between manual programming and automatic programming of machining center?
The main difference is the application scenario: for point processing or parts with less complex geometric shapes, the programming calculation is relatively simple, the amount of program is not large, and manual programming can be achieved. But for parts with complex shapes or contours that are not composed of straight lines or arcs; or spatial curved parts, even if they are composed of simple geometric elements, the amount of program is large. Because the calculation is quite cumbersome, manual programming is difficult and error-prone, it must be used Automatic programming method.
How to learn manual programming of machining center?
1. Familiar with the structure and process characteristics of drilling, milling, boring, grinding and planing machines,
2. Familiar with the properties of processed materials.
3. Solid basic knowledge of tool theory, master the conventional cutting amount of the tool, etc.
4. Familiar with the company's process specifications, guidelines, general requirements that can be achieved by various process processing, and process routes of conventional parts. Reasonable material consumption and working hours quota, etc.
5. Collect a certain amount of data on tools, machine tools, and mechanical standards. Particularly familiar with the tool system used by CNC machine tools.
6. Familiar with the selection and maintenance of coolant.
7. Have a common sense understanding of related types of work. For example: casting, electrical processing, heat treatment, etc.
8. Have a good fixture foundation.
9. Understand the assembly requirements and use requirements of the processed parts.
10. Have a good foundation of measurement technology.
What are the types of manual programming for machining centers?
1. Contour category: including shape and outer circle, inner hole and cavity, flying surface, etc.
2. Hole processing: including drilling, boring, reaming, and tapping.
The definition and difference between manual programming and automatic programming of machining centers are very clear. We can use automatic programming to make it faster.
