Calculating tool offset value is specially: the alternate position spike calculating the relative first cutter of other cutter after tool setting, and result of calculation is mended parameter region stored in the cutter of system.
Wherein, in the embodiment of the present application, described system also comprises display unit, and described display unit is made up of charactron, and numeral method can adopt Dynamic Announce, also can adopt static state display.
Wherein, in the embodiment of the present application, the method that systemic-function is selected has several different mode, and when using CRT monitor as display terminal, can make function menu, user can pass through menu setecting function.But economical CNC system is in order to reduce costs, generally without CRT monitor, and form display terminal with charactron.At this moment available band switch is by parallel interface composition function selection circuit.In master routine after system start-up and each later function program, by the position of cycle detection waver, and proceed to corresponding functional module.The tool setting mode adopted in lathe economical CNC system both can realize manual tool setting, can realize automatic tool preset again.Tool setting rod is the insulation pole of certain size, and its head adopts metal material, and with machine insulation, cutter is by lathe ground connection.During tool setting, knife rest carry its tools is close to tool setting rod, and tool setting signal sends into system.When point of a knife does not contact with tool setting rod, system acceptance is to high level, and when point of a knife contacts with tool setting rod, system acceptance is to low level.
The components and parts that Dynamic Announce uses are few, and circuit is simple, and row's charactron has a section to show and explicit adderss, a position, and section shows for controlling the character (font code) that will show, and position is aobvious to be used for controlling which numeral method.When making the some character of some numeral method, the font code section of the sending explicit adderss that first will show, make position show to should the position of charactron be 1 (or 0) in data again, and other position is 0 (or being 1), then send an explicit adderss by these data.
The components and parts that static state display uses are many, and circuit is complicated, and each charactron has a section display address, without explicit adderss, position.Each charactron has the latches data that a latch will show, only otherwise send new data to charactron, its displaying contents can not disappear this display packing.If display data are constant, do not need display to refresh, only when the data that will show change, just need to inject the data that will show to display.Owing to there being EPROM (be used for storage system program) in system, RAM (being used for depositing job sequence), interface circuits (be used for input, export) etc., every sheet internal memory all will have certain address realm, and charactron address can be continuous.Can adopt two-stage decode for addressing this problem, CS1 is as the EPROM chip selection signal of system, and CS2 is as the RAM chip selection signal of system, and CS3, CS4 and CS5 are as the chip selection signal of system.Code translator is used for processes and displays, if when having many row's charactrons in system, can use multiple code translator, the address wire that different code translator A, B, C terminations is different.
Technical scheme in above-mentioned the embodiment of the present application, at least has following technique effect or advantage:
Computer numerical control (CNC) system for lathe be designed to comprise owing to have employed: program editing unit, described program editing unit is used for the typing of job sequence, inspection and amendment; Parameter setting unit, described parameter setting unit is for setting drive gap, G00 speed, cutter parameters; Document handling unit, described document handling unit is used for job sequence and loads and unloading; Tool setting processing unit, described tool setting processing unit is used for manually and automatically detects tool position and radius parameter and automatic stored in system; Manual handle unit, described manual handle unit is used for hand feed; Continuous maching unit, described Continuous maching unit is used for performing job sequence continuously; Single hop machining cell, described single hop machining cell is used for each technical scheme performing one section of job sequence, system is simple, and meet processing request, without responsible system, so, efficiently solve existing numerically controlled lathe and there is the higher technical matters of cost, and then it is reasonable to achieve system, controlling lathe of low cost, reduces the technique effect of numerically controlled lathe cost.
