[讨论]用PROE/NC来加工塑料模型应注意的问题。

loosson

见到大家很少在讨论模具的加工，不知道有多少人用PROE/NC在做手板模型的加工，我初次涉足手板，请高手指点一二！
问题：
    1。对塑料加工来说，刀速S和进给F应该设置为多少为宜。
    2。正反面加工时因为塑料壁厚的问题，容易烧坏和变形，怎么样的加工顺序（包括装夹问题）会好一点。
   先发个一般的产品，大家讨论讨论，给我指点一下，也好填补这一片空白。
  塑料：ABS
  要求：里外都要加工，精度要求不高，有正负0.2就足够了。

我做的过程如下，希望大家提意见。
第一步：先加工里面的。开粗，用T10R2，余量0。2
<img src="attachments/dvbbs/2004-3/200436112212556.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2004-3/200436112212556.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
第二步：光刀，用T2R0，不留余量。<img src="attachments/dvbbs/2004-3/2004361132094459.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2004-3/2004361132094459.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
光刀时我用surface mill,走了很多空刀，没有经验，请大家指教。
第三步：把毛坯反过来，用胶水粘住底面，加工零件外表面，先留5MM固定位置以后再锣掉。
<img src="attachments/dvbbs/2004-3/2004361144273887.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2004-3/2004361144273887.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
最后一步，把剩下的5MM沿边锣掉，零件自动掉落。
<img src="attachments/dvbbs/2004-3/2004361153979964.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2004-3/2004361153979964.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

我这样的加工工艺有没有问题呢？

还是没有反应啊？
