FAULTY CNC MACHINE PROGRAMMING

- Jul 31, 2018-

NC machining is not exactly a foolproof process. In some instances, either a work piece or the machine itself could be directed in a harmful way. When this happens, a crash might occur, whereby tools or machine parts end up broken. The tools that could get damaged by a crash may include the vices or clamps that hold the work piece in place. When damage occurs within the machine, it could range from minor screw breakage to serious structural deformity.

The fact is, CNC equipment lacks the sentience to know exactly which distances are too far. Therefore, the tools must be exactly programmed in order to work without fault. If a program code is miscalculated, a CNC machine could be driven outside its physical bounds and cause an internal collision. Even though most of today’s CNC machines are manufactured with parameter boundaries, these inputs can be manipulated by operators.

Likewise, CNC tools are oblivious to a given environment. While certain CNC machines are equipped with spindle load sensing, others lack this feature. In the latter case, the software must be coded properly to ensure nothing goes off parameter, otherwise a crash would be the likely outcome. Even if a CNC machine is equipped with load sensors, a crash could still occur. When a tool function goes astray, it’s up to the operator to rectify the situation.
