Cutting speed planning system and method and non-transitory storage medium

A cutting speed planning method, adapted to plan a processing speed of a graphic path having a plurality of cutting routes, the cutting speed planning method comprising the steps of:

• comparing, with a graphic preprocessing engine, an actual cutting route attributed to the cutting routes and corresponding to a plurality of short straight paths with a simplified cutting route connected by a straight line between any two endpoints of the uniform short straight paths, wherein the simplified cutting route substitutes for an actual cutting route within a range defined by the two endpoints when an deviation between the simplified cutting route and the actual cutting route is less than a predetermined deviation threshold;
• calculating, with a first speed planning engine, a reasonable maximum cutting speed of each said cutting route according to a length of the cutting routes and an estimated maximum cutting speed corresponding to the graphic path;
• calculating, with an included angle calculation engine, an included angle between two adjacent ones of the cutting routes;
• making, with a second speed planning engine, a terminal cutting speed of each said cutting route equal to an initial cutting speed of a next cutting route;
• and
• changing each stage time of each said cutting route to an integer multiple of a digital control system period time and adjusting respective speed planning of the cutting routes, with a speed determination engine.

A non-transitory storage medium, adapted to store a plurality of program instructions executable when read by an electronic device to carry out the steps below and thus plan the processing speed of a graphic path having a plurality of cutting routes, the steps comprising:

• comparing, with a graphic preprocessing engine, an actual cutting route corresponding to a plurality of short straight paths of the cutting routes with a simplified cutting route defined by a straight line between any two endpoints of the short straight paths, wherein the simplified cutting route substitutes for the actual cutting route within a range defined by the two endpoints when the deviation between the simplified cutting route and the actual cutting route is less than a predetermined deviation threshold;
• calculating, with a first speed planning engine, a reasonable maximum cutting speed of each said cutting route according to a length of the cutting routes and an estimated maximum cutting speed corresponding to the graphic path;
• calculating, with an included angle calculation engine, an included angle between two adjacent ones of the cutting routes;
• making, with a second speed planning engine, the terminal cutting speed of each said cutting route equal to the initial cutting speed of a next cutting route;
• and
• changing each stage time of each said cutting route to an integer multiple of a digital control system period time and adjusting respective speed planning of the cutting routes, with a speed determination engine.
