A surprising curiosityI never thought that it would take so much time to design and manufacture such a simple part.Next time I will also calculate the time of my more complex projects just out of curiosity :)The complete process of the driver tool project and the necessary time commitment:A total of 2 pcs of custom made driver tools of 170 mm arm length and 1 pc of 250 mm arm length will be manufactured. These sizes are unique and cannot be used elsewhere.(Establishment of custom machine development for all components is not economically feasible)Purpose: An essential component of a production equipment in case of power outage, this component is used to return the equipment to its original position.Issue related inquiry: 1 hourMeasurement and modeling of components: 3 hoursPreparation of manufacturing drawings and workshop drawings: 2 hoursCoordination and correction of drawings and models: 1 hourSetting printing parameters and test prints: 2 hoursHandover of drawings for manufacturing and coordination: 5 hoursTask breakdown and process for internal production: 6 hoursDesign and negotiations for external production: several daysWelding, assembly and testing of components: 3-5 hoursPrototype testing and documentation revision: 4-5 hoursRepeat process for internal production, additional 6 hoursPreparation of production documentation and provision of access: 2 hoursTotal time commitment required: 28-33 hours
