Connecting other devices to PRG socket can damage connected device and AR904 process analogue calibrator.8.BUTTONS DESCRIPTIONa) Buttons functions in setpoint value display mode (normal mode)) )and 9: b) Buttons functions in parameters configuration mode (chapter 10)9.OUTPUTS SETPOINT VALUE CHANGEPressing [UP] or [DOWN] button while setpoint value is being displayed will change the value by pre-set step(parameter 6: , chapter 10, table 10). Changes of the output signal are proportional to changes of the displayed value. Pressing [SET] + [DOWN] buttons together will set output value immediately to lower rangevalue (2: or 4: ) while pressing [SET] + [UP] buttons together will set output value immediately to upperrange value (3: or 5: ). In addition, the output signal may be given also in parameters programming mode(parameter 7: ) and using serial interface RS485/RS232 or AR955 programmer (chapter 15, table 15). Moreover, it is possible to set the setpoint value outside of the display range based on the parameters 2: and 3:. The value of this override that can be set using the buttons is ±5% for 4÷20mA (2÷10V) output and 6,2% for the remaining outputs.10.CONFIGURATION PARAMETERS SETUPAll configuration parameters of the device are saved in the non-volatile EEPROM internal memory. Two parameters configuration methods are available:ing IP65 foil keyboard located on the front panel of the device:-From the setpoint value display mode enter configuration menu (press and hold for more than 1 second [UP] and [DOWN] buttons together). If parameter 13: (password protection is turned on), display will show message and then with first digit blinking. Using [UP] or [DOWN] button enter protection password (by default parameter 12: ). To proceed to the next digit or confirm the code use [SET] button.-After opening configuration menu you will see mnemonic parameter names ( <-> <-> <-> etc.), [UP] button will proceed to the next parameter and [DOWN] button will go back to theprevious parameter (all parameters are listed in table 10).-To change or display current parameter value press the [SET] button.-Using [UP] or [DOWN] button change the edited parameter value.-Confirm modified value using [SET] button or cancel using [UP] and [DOWN] buttons (simultaneously), then parameter name will be displayed.ing RS485/RS232 port or AR955 programmer and pc software ARSOFT-WZ1:-Connect process analogue calibrator to the PC port and start ARSOFT-WZ1 application.-After connection is established application window will display current setpoint value.-Device parameters can be displayed and modified in the parameters configuration window.-New paramete rs values have to be saved using “Zatwierdź zmiany” button.-Current configuration can be saved in a file or can be read from the file.CAUTION:-Do not use RS485/RS232 port and AR955 programmer simultaneously, because communication errors will occur.Table 10.

This function works as shown on the below charts (illustrations 11.1, 11.2, 11,3). To turn on this function you will have to configure soft start time (rising slope,parameter 8: , chapter 10) or soft stop time (falling slope, parameter 9: ) and trigger mode (parameter10: ). If both times are different than 0 (8: and 9: ) device outputs will generate triangle periodicalsignal. Amplitudes (end values) of output signals are defined by parameter 2: , 3: , 4: and 5:. Function is activated automatically after device power on (when parameter 10: ) or manually (10: ) using [SET] button (pressed and hold for more than 1.5 seconds). Moreover ramp function can be stopped and resumed at any time using [SET] button (short message will be displayed - start or - stop). Output status in this mode is refreshed 4 times per second.Illustration 11.1. Output status in soft start mode (parameter ).Illustration 11.2.

904L的成分以Cr、Ni等元素为主，属于难加工材料，切削加工性较差，主要原因如下。
1）904L不锈钢较之其他种类不锈钢，切削力更大。
因为904L硬度虽然不高（70—90HRB），但塑性较好，延伸率≥40%，断面收缩率≥50%，抗拉强度σb≥490MP a，屈服强度σ0.2≥216MPa，因而在切削过程中塑性变形大，使切削力增加。
2）导热系数低。
904L不锈钢的热导率（20℃时）为12.9W/（m·K），导热系数低，只有45钢的1/4左右（45钢的热导率为47.5W/（m·K））。
导热性是影响切削热传导的主要因素之一，被加工材料的导热性越低，由切屑和工件带走的热量就愈少，而刀具上积聚的热量就越多，使刀具极易磨损。
3）易生成积屑瘤。
由于904L不锈钢韧性大，所以在切削过程中与刀具材料的亲和力强，切削时刀具的前刀面与切屑底层金属发生强烈摩擦，在高温高压的作用下会产生粘附现象，生成积屑瘤，不易获得表面粗糙度要求高的加工表面。
4）切屑不易弯曲折断。
904L不锈钢的材料延伸率高，所以在切削过程中切屑不易弯曲而折断。
如果不采取适当措施，会影响切削过程的正常进行，而且容易划伤已加工表面，甚至还会使刀具崩刃和损坏。
由于904L不锈钢的以上特点，在用常规刀具和传统方法对其进行切削时，即使选择非常小的切削用量，刀具仍然极易磨损，加工效率低，且工件很难达到图样所要求的表面粗糙度和加工精度。
在这种背景下，笔者尝试借鉴先进的高速切削理念，进行904L不锈钢的铣削加工。
从理论上分析，在高速切削加工范围，随切削速度提高，切削力随之减少，有利于奥氏体不锈钢零件的切削加工。
