Mastercam后处理时间源代码，该方法所输出的时间只能放在程序尾部，如果需要放在程序头，需要使用者额外增加输出到程序头的代码，至于程序时间的准确与否，未经全面测试，部分测试时间可信。

由于代码较多，添加时严格按照下列方法进行。

1：换刀时间，这个需要根据实际情况进行相应的时间设定。

单位：分钟

tlchgtime        : 0.066 #Tool Change Time (* in Minutes *) I'ts 4 sec now

2：定义切削进给，快速进给等保存数据标签。

ttltime            : 0     #Total operation timetltime             : 0     #Feed timetrtime             : 0     #Rapid timetotal              : 0     #Total machine timetot_ltime          : 0     #Total FEED timetot_rtime          : 0     #Total RAPID time

3：定义记录x，y，z相对距离保存数据标签

len         : 0     #Length for calculationdx          : 0     #Delta xdy          : 0     #Delta ydz          : 0     #Delta z

3：定义钻孔类辅助数据保存标签

drill_length_r   : 0       # Drill length - RAPIDdrill_length_f   : 0       # Drill length - FEEDactual_drl_depth : 0      # Actual drill depth variablepeck_safe_dist   : 0.3 # Peck/Chip break safe distance for retratct into hole

4：定义他辅助开关

use_TC_pos       : yes$   # Calculate with Home positions @ TC? 0=No, 1=Yessav_X_Pos        : 0     # Saved X position, use X_home/Y_home/Z_home in rapids at TCsav_Y_Pos        : 0     # Saved Y position, use X_home/Y_home/Z_home in rapids at TCsav_Z_Pos        : 0     # Saved Z position, use X_home/Y_home/Z_home in rapids at TC

5：定义时间输出格式

time_format      : 2     # Time format of output times in NC code:                                               # 1 = 2h 14:25                    # 2 = 2hrs, 14mins, 25.08sec

6：定义时间数据格式

fs2 8 0^2 0^2n   #Decimal, 2 place, omit decimal if whole number, non-modal

7：定义时间数据输出类型

fmt      2 llenfmt      2 rlenfmt      2 llen_totalfmt      2 rlen_totalfmt      2 totalfmt      2 ttltimefmt      4 thrsfmt      4 tminfmt      8 tsec

8：初始化所有保存数据的标签

psetup           #Output of toolchange information  !gcode	llen = zero     #Reset counter for next tool	rlen = zero     #Reset counter for next tool	tltime = zero #Reset counter for next tool	trtime = zero #Reset counter for next tool	ttltime = zero #Reset counter for next tool	if use_TC_pos,	  [ 	   sav_X_Pos = x, sav_Y_Pos = y, sav_Z_Pos = z  	   x = xh, y = yh, z = zh 	   ptime_calc    	x = sav_X_Pos, y = sav_Y_Pos, z = sav_Z_Pos	 ]

9：统计进给距离，快速进给距离，时间等

ptooldata        #Total ending data for tool (Path Length and Times)         llen_total = llen_total + llen  #Keep running total for Program         rlen_total = rlen_total + rlen  #Keep running total for Program         tot_ltime = tot_ltime + tltime  #Total FEED time         tot_rtime = tot_rtime + trtime  #Total RAPID time         ttltime = tltime + trtime               #Calc. current Tool Time         total = ttltime + total + tlchgtime #Calc. total Program Time

10：时间转换，按60进制进行转换

pthrminsec       #Convert minutes to hr/min/sec format         thrs = int(ttltime / 60)         tmin = int(ttltime - thrs * 60)         tsec = (ttltime - thrs * 60 - tmin) * 60

11：时间输出

ptimeout                 #Output "times"         pthrminsec #Convert minutes to hr/min/sec format         if time_format = one,         [           #Output 'HOURS'           if thrs = one, *thrs, "hr, "           if thrs > one, *thrs, "hrs, "           #Output 'MINUTES'           if tmin = one, *tmin, "min, "           if tmin > one, *tmin, "min, "           #Output 'SECONDS'           if tsec > zero, *tsec, "sec"         ]         else,         [           result = newfs(five, tsec)           #Output 'HOURS'           if thrs > one, *thrs, "h "           #Output 'MINUTES' and 'SECONDS'           *tmin, ":", *tsec         ]

12：快速进给时间计算

ptimer           #Rapid time and length calc         rlen = rlen + len               #Running total RAPID length         trtime = rlen / pst_rpd_fr #Running total RAPID time

13：进给加工时间计算

ptimel           #Feed time and length calc         llen = llen + len         tltime = tltime + len / fr_pos

14：运行轨迹距离计算
