在现代生产环境中制程控制和优化是提高产品质量、降低不良率和提升经济效益的关键。在此背景下对生产过程中可能出现的问题进行全面、深入的分析和理解变得尤为重要。PFMEA（过程失效模式和影响分析）现场问题确认表就是一种强大的工具用于捕捉、理解并预防生产过程中可能出现的问题并且将PFMEA与现场控制有效关联起来更系统的策划与控制现场产品质量。更多信息欢迎参加我们的8月15-16日公开课《如何通过PFMEA制定控制计划、SOP及TPM》。
1.Building a bad part has been attempted by the cross function team at the Site.
2.The orientation of any feature or sub-component is effectively controlled if required (incorrect orientation, upside down, backwards, indexed inside out, radially misplaced, positional error).如需要，任何零件的方向都已经被有效的控制(错误的方向，上下放反，前后放反，顺序防错，内外放反，放射状的，位置放错)。3.Part is rejected if process is not fully performed4.Proper protection is in place throughout the process to prevent foreign objects from entering the assembly.5.Controls are in place to prevent incorrect setting of limits that deviate from the specifications and requirements of the drawings.工程中有控制可以防止错误的设置限度(与图纸、规格要求不符)。6.What happens if motion does not occur?7.What happens if motion is incomplete or short/long?如果动作没有完全，或者动作或长或短，会有什么问题发生?8.What happens if motion exceeds normal travel?9.What happens if motion is too fast/slow?10.What happens if force/torgue is toolow/high?11.What happens if part sticks to moving machine component?12.What happens if too much/little lubricant is present at process?如果过程现场有太多或者太少的润滑剂，会有什么问题发生?13.What happens if fail to detect a bad part?14.What happens if fails to accept a good part?15.What problems can occur if the equipment is not calibrated or verified properly?如果仪器没有校验或者适当的验证，会有什么问题发生?16.What happens if part is dropped?17.What happens if part skips operations?18.What happens if part is processed more than once?19.What happens if nonconforming part is not contained?20.What happens if part is not seated?21.What problems can occur if a part or component is missing during the process?22.What problems can occur if more than the required quantity of a component is installed?23.What problems can occur if an incorrect or similar part is installed (e.g., similar fastener, nut, etc)?如果安装了一个错误的或者类似的零件，会有什么问题发生(如:类似的螺钉，螺母等)?24.What happens if RPM is too high/low(inertia weld)?如果转速过快或者过慢(恒性焊)，会有什么问题发生?25.What happens if pressure is too high/low(inertia weld)?如果压力过高或者过低(惯性焊)，会有什么问题发生?26.What happens if shield gas flow is too high/low?如果保护气体的流速过快或者过慢，会有什么问题发生?27.What problems can occur if a weld is misaligned?28.What happens if weld time is too long/short?29.What happens if weld current is too high or low?30.What happens if crimp/rivet is too deep/shallow?31.What problems can occur if a crimp or rivet is misaligned?32.What problems can occur if a crimp/rivet segment breaks?33.What problems can occur if process parameters are incorrect (e.g., fixture pressure, voltage, current, etc.)?如果过程参数不正确，会有什么问题发生(夹具压力，电压，电流等)?34.Any other method tried to attempt a bad part?PFMEA现场问题确认表的使用有助于我们深入掌握生产过程，找出可能的问题并及时纠正。通过这些方法，我们能够更好地理解和预防可能的失效模式，从而在生产过程中实施更有效的控制和优化。这一过程不仅能提升产品质量，也能提高我们的生产效率，帮助我们实现生产和经济目标。因此，我们应当继续努力，不断优化我们的生产过程，以实现更高的质量和效率。如果需要了解更多内容，欢迎与我们联系，我们将提供专业的管理咨询和数字化流程软件帮助我们的顾客。邮箱:Marketing@tppconsultancy.com
