three. Milling quality analysis of the mold:
When the mold milling process is completed, there are many problems that affect the quality of the mold when testing the milling quality of the mold:
1. The geometry of the mold is not accurate.
2. The centerline of the mold is displaced and the shape of the cavity is not accurate.
3. The connection between the faces of the mold cavity is not accurate (R10 arc and two slopes).
4. The surface has obvious scratches.There are several reasons for these problems:
1. The reading was not careful and the correct shape of the mold was not correctly understood.
2. The determined processing benchmarks are not uniform with the design basis.
3. The scribing is not accurate, the milling steps are unreasonable, the fixture adjustment is incorrect, and the milling cutter selection is not appropriate.
4. Improper operation, milling the remaining part.
5. During the milling process, the measurement was incorrect.
   These reasons are not only the cause of the quality failure, but also the process of the teacher to strictly correct the internship operation. The operation must have strict quality control ability and rigorous work style. Every step must be considered. One step, leaving space, and strive to achieve accurate processing, accurate and timely measurement. Years of teaching practice shows that the students' ability to operate is learned in more than one less practice. Teachers must first strictly control, control is strong, and constantly strengthen training, it is able to train qualified personnel.
   In short, the problems generated in the practice teaching are various, and the processing quality of the workpiece directly reflects the skill level of the operator. When the problem arises, it is necessary to analyze the specific problem concretely, take correct methods to correct it in time, be good at grasping the main contradictions, and adopt scientific and effective methods to guide the students so that the technology and skill level are continuously improved during the completion of the internship operation. Qualified and useful.
