How to adjust the workpiece coordinate system during cnc processing in a cnc processing factory and what should be noted in the process!

During the cnc machining process, many adjustments need to be made. Due to the differences in the workpieces to be processed, some adjustments are required before operation. So, let's take a look at how to adjust the workpiece coordinate system in cnc machining with the help of the cnc processing factory editor.

When the operator adjusts the workpiece coordinate system, the reference point should be set outside the physical (geometric) lengths of all tools, at least on the tool position of the longest tool.

For the workpiece coordinate system on the workpiece installation diagram, the operator obtains it on the machine tool by setting the offset of the machine coordinate system. That is, the operator sets a reference point on the machine tool and finds the dimension between this reference point and the zero point of the workpiece coordinate system set by the programmer, and sets this dimension as the offset of the workpiece coordinate system.

On a lathe, the reference point can be set at the rotation center of the tool rest, on the tip of the reference tool, or at other positions. If no additional motion is attached, the zero of the programmer's instruction, that is, the reference point of the tool rest (machine tool), moves to the zero position of the offset. At this point, if the reference point is set at the rotation center of the tool rest, the tool rest is bound to collide with the workpiece. To ensure no collision, the reference points on the machine tool should not only be set outside the tool rest but also outside all the cutting tools. In this way, even when the tool is installed on the tool rest, the reference point will not collide with the workpiece.

On a milling machine, the reference points of the X and Y axes are on the centerline of the main shaft. However, the reference point of the Z-axis can be set at the end of the main shaft or at a certain point outside the end of the main shaft. If at the spindle end, when the instruction is zero, the spindle end will reach the zero position specified by the coordinate system. At this point, the end face key at the spindle end will collide with the workpiece. If there is a tool installed on the spindle, it will definitely collide with the workpiece. To ensure no collision, the reference point on the Z-axis should be set outside the length of all tools. Even without additional movements, the reference point will not collide with the workpiece.

The technical preparation process includes market research, forecasting, new product appraisal, process design, standardization review, etc. before the product goes into production.

(2) The technological process refers to the direct alteration of the dimensions, shapes, mutual positions of surfaces, surface roughness or properties of raw materials and semi-finished products to turn them into finished products. For instance, liquid forming, plastic forming, welding, powder forming, cutting processing, heat treatment, surface treatment, assembly, etc., all fall under the category of technological processes. A reasonable technological process is compiled into a technical document to guide production. This technical document is called a technological regulation.

(3) Auxiliary production processes refer to the auxiliary production activities necessary to ensure the normal operation of the basic production process.

(4) The production service process refers to the processes of organizing, transporting, keeping, storing, supplying raw materials, as well as packaging and selling products.
