On the 828D both MD and SD live in SRAM but do completely different jobs: MD defines what this machine physically is, and getting it wrong means alarms or even a crash; SD is the o...

伺服放大器故障后只对比维修费和换新价是错的。本文给出可修性判断、维修三个层次、更换三种选择，以及含停机成本的完整决策表，帮你算出真正的成本边界。

把海德汉 TNC 最常用的对话式程序段压成一页：程序结构 8 步、常用段全表、走刀要素（R0/RL/RR、DR、I）、常用 M 代码。现场写程序或读别人程序时对着查。

尺寸忽大忽小别再靠反复调刀补硬压 —— 刀补只修稳定的系统偏差，修不了随机漂移。用四条线分离法先判断「变化跟着什么走」：随件数走是刀具磨损，随时间走是热变形，随位置走是丝杠/螺距，随...

When an 828D drives an inverter or analog drive, the axis must be configured as an analog (analog setpoint output) axis rather than a digital one. This guide gives the values for M...

A copy-straight-to-the-machine Fanuc rigid tapping reference: 5200-5294 grouped into five blocks (enable bits, gear ratio, speed limit 5241-5244, gains and time constants, deviatio...

The most expensive mistake in a used CNC purchase is in the electrical cabinet. This 30-point field checklist covers history verification, power-off checks, live testing, and how t...

Classify servo vibration into 4 types (high-frequency squeal, low-frequency flutter, start/stop overshoot, machining ripple) and follow the right branch. Covers HRV filters, inerti...

How to read, search and clear Fanuc PMC alarm codes without losing your ladder.

828D/802D 数据丢了怎么救：先判断丢的是 NC/PLC/驱动/HMI 哪一层，读懂 4062 与 4060 相反的含义，再按内部备份、.ard 存档、缺省模式启动三条路径恢复。含 SUNRISE 口令与轴名错位提醒。
