It will increase your machining time by a second or two but it will help avoid a 3 Axis crash. If you are unsure it may be wise to move the X and Y axis first, then on a separate line, move down in Z. When using a rapid move, be aware of any clamps, vices, and parts that may be in your path.
The top speed is set by the machine parameters and therefore is only controllable by the operator using a rapid override control. It is used when the cutter or tool is not removing material so that the time it takes to machine the part is as quick as can be. G00 is the rapid travel command in G Code. In the example above I am moving the cutter 100mm to the left.
It is in this mode you will do the most damage if you didn’t get your tool set up right. Keep your hand on the feed knob and come in slow for the first time run. Some machinists like to rapid as close to the part as possible but I advise giving yourself at least 1mm clearance. This command is used when the tool is not touching the part to rapid move, normally used when going home for a tool change and returning with a new tool. It can be shortened to G0 as the older machines didn’t have much RAM and every bit counts.
