Ever marvel why and the way automakers like Porsche and BMW appear to have a cabin that’s screwed collectively a bit extra tightly than some competing automobiles? Some automakers have even earned a repute – deserved or in any other case – for shoddiness. Automakers all have their very own course of that ensures high quality for his or her automobiles. However for BMW that course of known as “cubing” and has been a part of their manufacturing line for no less than a decade.
What’s Cubing?
We acquired our first cubing expertise throughout a latest go to on the BMW Plant in San Luis Potosi. Cubing is among the first steps within the manufacturing course of and BMW has built-in this know-how for each upcoming mannequin. As a mannequin will get prepared for manufacturing, a full-size physique chassis is milled from stable aerospace-grade aluminum.
This mannequin permits BMW to watch how every half aligned and match collectively. If changes are wanted or one thing didn’t align completely, BMW might make modifications and re-evaluate to make sure optimum match. This method is particularly useful in pinpointing the supply of potential points, significantly simplifying product testing.
In a nutshell, cubing ensures all the things from headlights to inside upholstery and switchgear match cosy and correct. Through the use of exact measuring instruments, inconsistencies may be noticed at a scale right down to tenths of a millimeter. BMW even goes so far as to make sure the aluminum physique is saved in a climate-controlled setting to scale back environmental impacts.
Some processes additionally use augmented actuality which permits BMW engineers to overlay digital components onto the mannequin to evaluate compatibility with out bodily meeting.
After BMW mills out the aluminum physique, components suppliers ship pattern components for take a look at fitment. BMW matches the half and scans the mannequin in opposition to the “produced” unit to examine for variances. The scan even takes into consideration paint thickness, which might ever so barely influence ultimate match and end. Testing out parts earlier than the automotive sees manufacturing reduces the possibilities for recollects and permits BMW to find wonky or ill-fitting components earlier than the general public.
Cubing Ain’t Low cost; However Neither is a BMW
After we visited the plant in San Luis Potosi, BMW claimed that the cubing course of can value within the single digit thousands and thousands. We’re unsure if that determine is inclusive of the varied machines and software program required to precisely “dice.” Both means, that’s some critical scratch, and it’s additionally the rationale cubing isn’t fairly what you’d name an business customary. However when you think about the match and end of their automobiles – and the repute fellow cuber Porsche boasts – the outcomes are clearly palpable.
Cubing is important on the Mexico plant. Not solely to make sure high quality of present merchandise – notably, it’s the middle of world market manufacturing for the fascinating M2 – however for what’s to return. San Luis Potosi might be tasked with Neue Klasse manufacturing for the US market. These early fashions will go away an enduring impression on North American buyers. Cubing will little doubt be utilized in full pressure to the brand new EV fashions.
As automobiles and the manufacturing course of more and more develop into streamlined and unified throughout automakers, particulars like match and end will begin to matter an increasing number of. It’s among the finest methods to face out from the gang, particularly as an automaker like BMW that touts “luxurious” branding. I say: let the cubing begin. Forbes additionally put collectively an important article on BMW Cubing.
