1、 Serious mistakes that cannot be presented in mechanical planning
1. Planning that violates laws and regulations
2. Matters that do not comply with the terms of the contract or have been resolved through internal meetings with the client and the company
3. No planning basis (excluding empirical planning or feasible innovative planning, creative planning)
4. Failure to meet functional and production capacity requests
5. Cannot be disassembled or assembled
6. The selection presents a major mistake
7. Incorrect selection of raw materials for the primary component
8. There are significant errors in the formulas and parameters presented in the accounting book
9. Errors in primary scale, elevation, coordinates, etc
10. Severe attacks and
11. Excessive capacity of equipment
12. There are safety hazards present
13. Other serious mistakes
2、 Some common mistakes made in mechanical planning
1. Does not comply with the drawing rules
2. Accounting (accounting book) is not acceptable
3. Skill and operation requests (annotations on the drawing) are not acceptable
4. Errors in the data sheet and component list
5. There is inconvenience in maintenance and protection
6. Typical bumps
7. Making mistakes in civil service, roughness, geometric accuracy, etc. may not be feasible
8. Common scale errors
9. View error
10. Errors in words, sentences, etc. (accumulating more than 5 errors is considered as 1 common mistake)
11. Other common faults
3、 Several details that are easily overlooked in mechanical planning
1. Smooth point planning for rolling parts (manual or automatic)
2. Rolling part planning safety cover (with observation door)
3. Plan lifting screw holes or lifting ears for components weighing over 20 kilograms
4. Planning and positioning of bearing seat installation position and adjusting bolts for bearing capacity
5. Planning and adjusting gaskets for connection surfaces involving height changes or adjustments
6. Planning positioning pins or positioning blocks for bolted connections
7. Distinguish between on-site welding components and factory welding
8. Special welding with non general welding requirements specified
9. Sectional view of oil seal reflects the direction of oil seal
10. Loose double nuts for large item connection planning
11. Indicate the scale of non painting
12. The motion scale (initial and final directions) and motion trajectory of the moving parts indicate
13. Safety planning for homework and non homework situations
14. Strengthen load-bearing areas (such as reinforcing ribs) and weaken non load-bearing areas (such as weight reducing holes)
15. Improve the planning of linear public service, cooperative public service, and positional public service
16. Reasonably plan the processing roughness
17. Accurately write skill requests
