ABB 5SHX08F4502 可控硅通过使用绝对位置传感器(光学编码器条或光盘)来验证运动是否发生，或者使用驱动系统上的扭矩传感器或功率传感器来检测机器应该只是移动而不是切割时的异常应变，可以进行碰撞检测和避免，但这些并不是大多数业余CNC工具的常见组件。相反，大多数业余爱好的数控工具只是依赖于假定的精度步进电机其响应磁场变化旋转特定的度数。人们通常认为步进器非常精确，从不出错，因此刀具位置监控只需计算一段时间内发送给步进器的脉冲数。步进器位置监控的替代手段通常不可用，因此碰撞或滑动检测是不可能的。

ABB 5SHX08F4502 可控硅商用CNC金属加工机使用闭环反馈控制轴运动。在闭环系统中，控制器用绝对或来监控每个轴的实际位置增量式编码器。正确的控制编程将减少撞车的可能性，但仍由操作员和程序员来确保机器安全运行。然而，在2000年和2010年期间，加工仿真软件迅速成熟，整个机床外壳(包括所有轴、主轴、卡盘、转塔、刀架、尾座、夹具、夹具和坯料)用以下工具精确建模不再罕见三维实体模型，这使得模拟软件能够相当准确地预测一个周期是否会发生碰撞。尽管这种模拟并不新鲜，但由于计算技术的进步，其准确性和市场渗透率正在发生巨大变化。

ABB 5SHX08F4502 thyristor enables collision detection and avoidance by using an absolute position sensor (optical encoder bar or disc) to verify that motion is occurring, or by using a torque sensor or power sensor on the drive system to detect abnormal strain when the machine should only be moving rather than cutting. But these are not common components of most amateur CNC tools. Instead, most hobbyist CNC tools simply rely on the assumed accuracy of stepper motors that rotate a specific number of degrees in response to magnetic field changes. Steppers are often thought to be very accurate and never make mistakes, so tool position monitoring simply counts the number of pulses sent to the stepper over a period of time. Alternative means of stepper position monitoring are often not available, so collision or slip detection is not possible.

The ABB 5SHX08F4502 thyristor commercial CNC metal machining machine uses closed-loop feedback to control shaft movement. In a closed-loop system, the controller uses absolute or incremental encoders to monitor the actual position of each axis. Proper control programming will reduce the likelihood of a crash, but it is still up to the operator and programmer to ensure that the machine operates safely. However, during 2000 and 2010, machining simulation software matured rapidly, and it was no longer uncommon for the entire machine housing (including all shafts, spines, chucks, turrets, tool holders, tailstock, jigs, jigs, and billets) to be accurately modeled with the following tools 3D solid models, which allowed the simulation software to predict fairly accurately whether a collision would occur during a cycle. Although such simulations are not new, their accuracy and market penetration are changing dramatically due to advances in computing technology.
